• XML::LibXML::XPathContext - Question

  - by sid_com

  This script works with and without XPathContext. Why should I use it with XPathContext? #!/usr/bin/env perl use warnings; use strict; use XML::LibXML; use 5.012; my $parser = XML::LibXML->new; my $doc = $parser->parse_string(<<EOT); <?xml version="1.0"?> <xml> Text im Dokument <element id="myID" name="myname" style="old" /> <object objid="001" objname="Object1" /> <element id="002" name="myname" /> </xml> EOT #/ # without XPathContext my $nodes = $doc->findnodes( '/xml/element[@id=002]' ); # with XPathContext #my $root = $doc->documentElement; #my $xc = XML::LibXML::XPathContext->new( $root ); #my $nodes = $xc->findnodes( '/xml/element[@id=002]' ); for my $node ( $nodes->get_nodelist ) { say "Node: ", $node->nodeName; print "Attribute: "; print $_->getName, '=', $_->getValue, ' ' for $node->attributes; say ""; }

• Read Parent nodes only from XML using LINQToXML

  - by ItsMeSri

  I have XML string that has parent nodes "Committee" and inside that another child node "Committee" is there. When I am using "from committee in xDocument.DescendantsAndSelf("Committee")" it is reading childnode also, but I don't want to read child nodes, I just want to read Parent nodes only. <Committee> <Position>STAFF</Position> <Appointment>1/16/2006</Appointment> <Committee>PPMSSTAFF</Committee> <CommitteeName>PPMS Staff</CommitteeName> <Expiration>12/25/2099</Expiration> </Committee> <Committee> <Position>STAFF</Position> <Appointment>4/16/2004</Appointment> <Committee>PMOSSTAFF</Committee> <CommitteeName>PPMS </CommitteeName> <Expiration>12/25/2099</Expiration> </Committee> XElement xDocument= XElement.Parse(xml); var committeeXmls = from Committee in xDocument.Descendants("Committee") select new { CommitteeName = Committee.Element("CommitteeName"), Position = Committee.Element("Position"), Appointment = Committee.Element("Appointment"), Expiration = Committee.Element("Expiration") }; int i = 0; foreach (var committeeXml in committeeXmls) { if (committeeXml != null) { drCommittee = dtCommittee.NewRow(); drCommittee["ID"] = ++i; drCommittee["CommitteeName"] = committeeXml.CommitteeName.Value; drCommittee["Position"] = committeeXml.Position.Value; drCommittee["Appointment"] = committeeXml.Appointment.Value; drCommittee["Expiration"] = committeeXml.Expiration.Value; dtCommittee.Rows.Add(drCommittee); // educationXml.GraduationDate.Value, educationXml.Major.Value); } }

• Adding Functions to an Implementation of Vector

  - by Meursault

  I have this implementation of vector that I've been working on for a few days using examples from a textbook: #include <iostream> #include <string> #include <cassert> #include <algorithm> #include <cstring> // Vector.h using namespace std; template <class T> class Vector { public: typedef T * iterator; Vector(); Vector(unsigned int size); Vector(unsigned int size, const T & initial); Vector(const Vector<T> & v); // copy constructor ~Vector(); unsigned int capacity() const; // return capacity of vector (in elements) unsigned int size() const; // return the number of elements in the vector bool empty() const; iterator begin(); // return an iterator pointing to the first element iterator end(); // return an iterator pointing to one past the last element T & front(); // return a reference to the first element T & back(); // return a reference to the last element void push_back(const T & value); // add a new element void pop_back(); // remove the last element void reserve(unsigned int capacity); // adjust capacity void resize(unsigned int size); // adjust size void erase(unsigned int size); // deletes an element from the vector T & operator[](unsigned int index); // return reference to numbered element Vector<T> & operator=(const Vector<T> &); private: unsigned int my_size; unsigned int my_capacity; T * buffer; }; template<class T>// Vector<T>::Vector() { my_capacity = 0; my_size = 0; buffer = 0; } template<class T> Vector<T>::Vector(const Vector<T> & v) { my_size = v.my_size; my_capacity = v.my_capacity; buffer = new T[my_size]; for (int i = 0; i < my_size; i++) buffer[i] = v.buffer[i]; } template<class T>// Vector<T>::Vector(unsigned int size) { my_capacity = size; my_size = size; buffer = new T[size]; } template<class T>// Vector<T>::Vector(unsigned int size, const T & initial) { my_size = size; //added = size my_capacity = size; buffer = new T [size]; for (int i = 0; i < size; i++) buffer[i] = initial; } template<class T>// Vector<T> & Vector<T>::operator = (const Vector<T> & v) { delete[ ] buffer; my_size = v.my_size; my_capacity = v.my_capacity; buffer = new T [my_size]; for (int i = 0; i < my_size; i++) buffer[i] = v.buffer[i]; return *this; } template<class T>// typename Vector<T>::iterator Vector<T>::begin() { return buffer; } template<class T>// typename Vector<T>::iterator Vector<T>::end() { return buffer + size(); } template<class T>// T& Vector<T>::Vector<T>::front() { return buffer[0]; } template<class T>// T& Vector<T>::Vector<T>::back() { return buffer[size - 1]; } template<class T> void Vector<T>::push_back(const T & v) { if (my_size >= my_capacity) reserve(my_capacity +5); buffer [my_size++] = v; } template<class T>// void Vector<T>::pop_back() { my_size--; } template<class T>// void Vector<T>::reserve(unsigned int capacity) { if(buffer == 0) { my_size = 0; my_capacity = 0; } if (capacity <= my_capacity) return; T * new_buffer = new T [capacity]; assert(new_buffer); copy (buffer, buffer + my_size, new_buffer); my_capacity = capacity; delete[] buffer; buffer = new_buffer; } template<class T>// unsigned int Vector<T>::size()const { return my_size; } template<class T>// void Vector<T>::resize(unsigned int size) { reserve(size); my_size = size; } template<class T>// T& Vector<T>::operator[](unsigned int index) { return buffer[index]; } template<class T>// unsigned int Vector<T>::capacity()const { return my_capacity; } template<class T>// Vector<T>::~Vector() { delete[]buffer; } template<class T> void Vector<T>::erase(unsigned int size) { } int main() { Vector<int> v; v.reserve(2); assert(v.capacity() == 2); Vector<string> v1(2); assert(v1.capacity() == 2); assert(v1.size() == 2); assert(v1[0] == ""); assert(v1[1] == ""); v1[0] = "hi"; assert(v1[0] == "hi"); Vector<int> v2(2, 7); assert(v2[1] == 7); Vector<int> v10(v2); assert(v10[1] == 7); Vector<string> v3(2, "hello"); assert(v3.size() == 2); assert(v3.capacity() == 2); assert(v3[0] == "hello"); assert(v3[1] == "hello"); v3.resize(1); assert(v3.size() == 1); assert(v3[0] == "hello"); Vector<string> v4 = v3; assert(v4.size() == 1); assert(v4[0] == v3[0]); v3[0] = "test"; assert(v4[0] != v3[0]); assert(v4[0] == "hello"); v3.pop_back(); assert(v3.size() == 0); Vector<int> v5(7, 9); Vector<int>::iterator it = v5.begin(); while (it != v5.end()) { assert(*it == 9); ++it; } Vector<int> v6; v6.push_back(100); assert(v6.size() == 1); assert(v6[0] == 100); v6.push_back(101); assert(v6.size() == 2); assert(v6[0] == 100); v6.push_back(101); cout << "SUCCESS\n"; } So far it works pretty well, but I want to add a couple of functions to it that I can't find examples for, a SWAP function that would look at two elements of the vector and switch their values and and an ERASE function that would delete a specific value or range of values in the vector. How should I begin implementing the two extra functions?

• Numpy: Sorting a multidimensional array by a multidimensional array

  - by JD Long

  Forgive me if this is redundant or super basic. I'm coming to Python/Numpy from R and having a hard time flipping things around in my head. I have a n dimensional array which I want to sort using another n dimensional array of index values. I know I could wrap this in a loop but it seems like there should be a really concise Numpyonic way of beating this into submission. Here's my example code to set up the problem where n=2: a1 = random.standard_normal(size=[2,5]) index = array([[0,1,2,4,3] , [0,1,2,3,4] ]) so now I have a 2 x 5 array of random numbers and a 2 x 5 index. I've read the help for take() about 10 times now but my brain is not groking it, obviously. I thought this might get me there: take(a1, index) array([[ 0.29589188, -0.71279375, -0.18154864, -1.12184984, 0.25698875], [ 0.29589188, -0.71279375, -0.18154864, 0.25698875, -1.12184984]]) but that's clearly reordering only the first element (I presume because of flattening). Any tips on how I get from where I am to a solution that sorts element 0 of a1 by element 0 of the index ... element n?

• how can I write a schema that produce an unordered xml with extension

  - by ekeren

  In the following schema I am trying to make an unordered xml that extends simpleConfigurationObject: <xs:complexType name="forTestingConfigurationObjectCreator"> <xs:complexContent> <xs:extension base="simpleConfigurationObject"> <xs:all> <xs:element name="a" type="xs:string"/> <xs:element name="b" type="xs:string" minOccurs="0"/> </xs:all> </xs:extension> </xs:complexContent> </xs:complexType> <xs:complexType name="simpleConfigurationObject"> <xs:all> <xs:element name="base" type="xs:string" minOccurs="0"/> </xs:all> </xs:complexType> But I get the following error on the xs:all "all is not the only particle in the group, or is being used as an extension" (which is correct) Off-course if put the base element inside the xs:all and not use xs:extension at all I will get an unordered schema restriction. (but that is not what I want) The question is: how can I produce unordered schema with the extension? Thanks

• How to select form input based on label inner HTML?

  - by Shane

  I have multiple forms that are dynamically created with different input names and id's. The only thing unique they will have is the inner HTML of the label. Is it possible to select the input via the label inner HTML with jQuery? Here is an example of one of my patient date of birth blocks, there are many and all unique except for innerHTML. <div class="iphorm-element-spacer iphorm-element-spacer-text iphorm_1_8-element-spacer"> <label for="iphorm_081a9e2e6b9c83d70496906bb4671904150cf4b43c0cb1_8">events=Object { mouseover=[1], mouseout=[1]}handle=function()data=Object { InFieldLabels={...}} Patient DOB <span class="iphorm-required">*</span> </label> <div class="iphorm-input-wrap iphorm-input-wrap-text iphorm_1_8-input-wrap"> <input id="iphorm_081a9e2e6b9c83d70496906bb4671904150cf4b43c0cb1_8" class="iphorm-element-text iphorm_1_8" type="text" value="" name="iphorm_1_8">events=Object { focus=[1], blur=[1], keydown=[1], more...}handle=function() </div> <div class="iphorm-errors-wrap iphorm-hidden"> </div> This is in a Wordpress Plugin and because we are building to allow employees to edit their sites (this is actually a Wordpress Network), we do not want to alter the plugin if possible. Note that the label "for" and the input "id" share the same dynamic key, so this might be a way to maybe get the id, but wanted to see if there is a shorter way of doing this.

• How do I expose the columns collection of GridView control that is inside a user control

  - by Christopher Edwards

  See edit. I want to be able to do this in the aspx that consumes the user control. <uc:MyControl ID="MyGrid" runat="server"> <asp:BoundField DataField="FirstColumn" HeaderText="FirstColumn" /> <asp:BoundField DataField="SecondColumn" HeaderText="SecondColumn" /> </uc> I have this code (which doesn't work). Any ideas what I am doing wrong? VB Partial Public Class MyControl Inherits UserControl <System.Web.UI.IDReferenceProperty(GetType(DataControlFieldCollection))> _ Public Property Columns() As DataControlFieldCollection Get Return MyGridView.Columns End Get Set(ByVal value As DataControlFieldCollection) ' The Columns collection of the GridView is ReadOnly, so I rebuild it MyGridView.Columns.Clear() For Each c As DataControlField In value MyGridView.Columns.Add(c) Next End Set End Property ... End Class C# public partial class MyControl : UserControl {         [System.Web.UI.IDReferenceProperty(typeof(DataControlFieldCollection))]     public DataControlFieldCollection Columns {         get { return MyGridView.Columns; }         set {             MyGridView.Columns.Clear();             foreach (DataControlField c in value) {                 MyGridView.Columns.Add(c);             }         }     } ... } EDIT: Actually it does work, but auto complete does not work between the uc:MyControl opening and closing tags and I get compiler warnings:- Content is not allowed between the opening and closing tags for element 'MyControl'. Validation (XHTML 1.0 Transitional): Element 'columns' is not supported. Element 'BoundField' is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing. So I guess I need to use some sort of directive to tell the complier to expect content between the tags. Any ideas?

• Doctrine2 ArrayCollection

  - by boosis

  Ok, I have a User entity as follows <?php class User { /** * @var integer * @Id * @Column(type="integer") * @GeneratedValue */ protected $id; /** * @var \Application\Entity\Url[] * @OneToMany(targetEntity="Url", mappedBy="user", cascade={"persist", "remove"}) */ protected $urls; public function __construct() { $this->urls = new \Doctrine\Common\Collections\ArrayCollection(); } public function addUrl($url) { // This is where I have a problem } } Now, what I want to do is check if the User has already the $url in the $urls ArrayCollection before persisting the $url. Now some of the examples I found says we should do something like if (!$this->getUrls()->contains($url)) { // add url } but this doesn't work as this compares the element values. As the $url doesn't have id value yet, this will always fail and $url will be dublicated. So I'd really appreciate if someone could explain how I can add an element to the ArrayCollection without persisting it and avoiding the duplication? Edit I have managed to achive this via $p = function ($key, $element) use ($url) { if ($element->getUrlHash() == $url->getUrlHash()) { return true; } else { return false; } }; But doesn't this still load all urls and then performs the check? I don't think this is efficient as there might be thousands of urls per user.

• .post inside jQuery.validator.addMethod always returns false :(

  - by abdullah kahraman

  Hello! I am very new to jQuery and javascript programming. I have a program below that checks whether username is taken or not. For now, the PHP script always returns if(isset($_POST["username"]) )//&& isset($_POST["checking"])) { $xml="<register><message>Available</message></register>"; echo $xml; } Login function works, but username checking doesn't. Any ideas? Here is all of my code: $(document).ready(function() { jQuery.validator.addMethod("checkAvailability",function(value,element){ $.post( "login.php" , {username:"test", checking:"yes"}, function(xml){ if($("message", xml).text() == "Available") return true; else return false; }); },"Sorry, this user name is not available"); $("#loginForm").validate({ rules: { username: { required: true, minlength: 4, checkAvailability: true }, password:{ required: true, minlength: 5 } }, messages: { username:{ required: "You need to enter a username." , minlength: jQuery.format("Your username should be at least {0} characters long.") } }, highlight: function(element, errorClass) { $(element).fadeOut("fast",function() { $(element).fadeIn("slow"); }) }, success: function(x){ x.text("OK!") }, submitHandler: function(form){send()} }); function send(){ $("#message").hide("fast"); $.post( "login.php" , {username:$("#username").val(), password:$("#password").val()}, function(xml){ $("#message").html( $("message", xml).text() ); if($("message", xml).text() == "You are successfully logged in.") { $("#message").css({ "color": "green" }); $("#message").fadeIn("slow", function(){location.reload(true);}); } else { $("#message").css({ "color": "red" }); $("#message").fadeIn("slow"); } }); } $("#newUser").click(function(){ return false; }); });

• Problem Writing Linq2Xml Query

Any tips as to how this should be done? Thanks

Create a DTD to record the sellers of merchandise to the Second-hand shop.

Note 1: it may help you to create lists for both sellers and for sighted_identification. Note 2: The shops database stores the sighted identification of sellers as p, dl, bc and mc rather than by their full name, so creating an entity for each type is required. Note 3: Your XSLT should order the sellers by sellerID – for this reason don’t have them ordered correctly in the XML file – rather sort the sellerID within the XSLT. OUTPUT SHOULD BE SOMETHING LIKE THIS SELLER ID : NAME: ADDRESS : PHONE : IDENTIFICATION : IDENTIFICATION : IDENTIFICATION :

• Strange problem with vectors.

  - by Catalin Dumitru

  I have a really strange problem with stl vectors in which the wrong destructor is called for the right object when I call the erase method if that makes any sense. My code looks something like this: for(vector<Category>::iterator iter = this->children.begin(); iter != this->children.end(); iter++) { if((*iter).item == item) { this->children.erase(iter); return; } ------------------------- } It's just a simple function that finds the element in the vector which has some item to be searched, and removes said element from the vector. My problem is than when the erase function is called, and thus the object which the iterator is pointing at is being destroyed, the wrong destructor is being called. More specific the destructor of the last element in the vector is being called, and not of the actual object being removed. Thus the memory is being removed from the wrong object, which will still be an element in the vector, and the actual object which is removed from the vector, still has all of it's memory intact. The costructor of the object looks like this: Category::Category(const Category &from) { this->name = from.name; for(vector<Category>::const_iterator iter = from.children.begin(); iter != from.children.end(); iter++) this->children.push_back((*iter)); this->item = new QTreeWidgetItem; } And the destructor Category::~Category() { this->children.clear(); if(this->item != NULL) { QTreeWidgetItem* parent = this->item->parent(); if(parent != NULL) parent->removeChild(this->item); delete this->item; } }

• Efficient way of calculating average difference of array elements from array average value

  - by Saysmaster

  Is there a way to calculate the average distance of array elements from array average value, by only "visiting" each array element once? (I search for an algorithm) Example: Array : [ 1 , 5 , 4 , 9 , 6 ] Average : ( 1 + 5 + 4 + 9 + 6 ) / 5 = 5 Distance Array : [|1-5|, |5-5|, |4-5|, |9-5|, |6-5|] = [4 , 0 , 1 , 4 , 1 ] Average Distance : ( 4 + 0 + 1 + 4 + 1 ) / 5 = 2 The simple algorithm needs 2 passes. 1st pass) Reads and accumulates values, then divides the result by array length to calculate average value of array elements. 2nd pass) Reads values, accumulates each one's distance from the previously calculated average value, and then divides the result by array length to find the average distance of the elements from the average value of the array. The two passes are identical. It is the classic algorithm of calculating the average of a set of values. The first one takes as input the elements of the array, the second one the distances of each element from the array's average value. Calculating the average can be modified to not accumulate the values, but caclulating the average "on the fly" as we sequentialy read the elements from the array. The formula is: Compute Running Average of Array's elements ------------------------------------------- RA[i] = E[i] {for i == 1} RA[i] = RA[i-1] - RA[i-1]/i + A[i]/i { for i > 1 } Where A[x] is the array's element at position x, RA[x] is the average of the array's elements between position 1 and x (running average). My question is: Is there a similar algorithm, to calculate "on the fly" (as we read the array's elements), the average distance of the elements from the array's mean value? The problem is that, as we read the array's elements, the final average value of the array is not known. Only the running average is known. So calculating differences from the running average will not yield the correct result. I suppose, if such algorithm exists, it probably should have the "ability" to compensate, in a way, on each new element read for the error calculated as far.

• How do I find, count, and display unique elements of an array using Perl?

  - by Luke

  I am a novice Perl programmer and would like some help. I have an array list that I am trying to split each element based on the pipe into two scalar elements. From there I would like to spike out only the lines that read ‘PJ RER Apts to Share’ as the first element. Then I want to print out the second element only once while counting each time the element appears. I wrote the piece of code below but can’t figure out where I am going wrong. It might be something small that I am just overlooking. Any help would be greatly appreciated. ## CODE ## my @data = ('PJ RER Apts to Share|PROVIDENCE', 'PJ RER Apts to Share|JOHNSTON', 'PJ RER Apts to Share|JOHNSTON', 'PJ RER Apts to Share|JOHNSTON', 'PJ RER Condo|WEST WARWICK', 'PJ RER Condo|WARWICK'); foreach my $line (@data) { $count = @data; chomp($line); @fields = split(/\|/,$line); if (($fields[0] =~ /PJ RER Apts to Share/g)){ @array2 = $fields[1]; my %seen; my @uniq = grep { ! $seen{$_}++ } @array2; my $count2 = scalar(@uniq); print "$array2[0] ($count2)","\n" } } print "$count","\n"; ## OUTPUT ## PROVIDENCE (1) JOHNSTON (1) JOHNSTON (1) JOHNSTON (1) 6

Now I'm trying to get the href value of an tag that is found in the second of each . I'd like to include this in the $results array, but I'm not sure how to do this. The third foreach statement gets them but then I need to merge $links with $results. Ideally I'd also get the links in the second foreach statement. Does anyone know how? $i = 0; foreach( $urls as $u ) { $html = file_get_html($u); foreach($html->find('.results tbody tr') as $element) { $result[$i] = $this->extract($element->plaintext); $i++; } foreach($html->find('.results tbody tr a') as $element) { $links[$i] = $element->href; $i++; } } print_r($result); print_r($links); die;

• jquery validate not submitting after modal close bootstrap

  - by Mariana Hernandez

  I have a modal where i insert some data, but when i open the modal, close it, and the click the modal show button again, it doesnt submit of course because the validate is "acting" in the modal, but i closed it so its not showing... how can i prevent this? thanks it is similar to this jquery functions within modal only work on first open, after close and re-open they stop working but my functions are <script> $(document).ready(function() { $("#myModal").modal('show'); }); </script> and the validation one <script> $(document).ready(function(){ $('#form1').validate( { ignore: "", rules: { usu_login: { required: true }, usu_password: { required: true }, usu_email: { required: true }, usu_nombre1: { required: true }, usu_apellido1: { required: true }, usu_fecha_nac: { required: true }, usu_cedula: { required: true }, usu_telefono1: { required: true }, rol_id: { required: true }, dependencia_id: { required: true }, }, highlight: function(element) { $(element).closest('.grupo').addClass('has-error'); if($(".tab-content").find("div.tab-pane.active:has(div.has-error)").length == 0) { $(".tab-content").find("div.tab-pane:hidden:has(div.has-error)").each(function(index, tab) { var id = $(tab).attr("id"); $('a[href="#' + id + '"]').tab('show'); }); } }, unhighlight: function(element) { $(element).closest('.grupo').removeClass('has-error'); } }); }); </script> So i dont know how to apply the answer of the above =(

• XML: what processing rules apply for values intertwined with tags?

  - by iCE-9

  I've started working on a simple XML pull-parser, and as I've just defuzzed my mind on what's correct syntax in XML with regards to certain characters/sequences, ignorable whitespace and such (thank you, http://www.w3schools.com/xml/xml_elements.asp), I realized that I still don't know squat about what can be sketched up as the following case (which Validome finds well-formed very much; note that I only want to use xml files for data storage, no entities, DTD or Schemas needed): <bookstore> <book id="1"> <author>Kurt Vonnegut Jr.</author> <title>Slapstick</title> </book> We drop a pie here. <book id="2">Who cares anyway? <author>Stephen King</author> <title>The Green Mile</title> </book> And another one here. <book id="3"> <author>Next one</author> <title>This time with its own title</title> </book> </bookstore> "We drop a pie here." and "And another one here." are values of the 'bookstore' element. "Who cares anyway?" is a value related to the second 'book' element. How are these processed, if at all? Will "We drop a pie here." and "Another one here." be concatenated to form one value for the 'bookstore' element, or are they treated separately, stored somewhere, affecting the outcome of the parsing of the element they belong to, or...?

• jQuery validate and tabs

  - by ntan

  Hi i am using jQuery validate for my form validation. The form is inside tabs.When i get an error i add an icon to the tab that error exist to be visual by the user So far so good. My problem is that after correct the error i can not remove the error in tab icon. I was assuming that validator is accessible via success but its not Assuming that the first tab (tab0) has 3 field for validation (field1,field2,field3) Here is the full code $("form#Form1") .validate({ invalidHandler: function(form, validator) { //TAB 0 if (validator.errorMap.field1 != "" && validator.errorMap.field2 != "" && validator.errorMap.field3 != "") { if ($("#tabs>ul>li").eq(0).find("img").length == 0) { $("#tabs>ul>li").eq(0).prepend("<img src=\"error.gif\">"); } } }, errorClass: "errorField", errorElement: "p", errorPlacement: function(error, element) { var parent = element.parent(); parent.addClass("error"); error.prependTo( parent ); }, //validator in not accessible via success //so my code its not working success: function(element,validator) { var parent = element.parent(); parent.removeClass("error"); $(parent).children("p.errorField").remove(); //TAB 0 if (validator.errorMap.field1 == "" && validator.errorMap.field2 == "" && validator.errorMap.field2 == "") { if ($("#tabs>ul>li").eq(0).find("img").length == 0) { $("#tabs>ul>li").eq(0).find("img").remove(); } } }, rules: { field1: { required: true }, field2: { required: true }, field3: { required: true } } }); Any suggestion is welcome.

• .Net xsd.exe tool doesn't generate all types

  - by Mrchief

  For some reason, MS .Net (v3.5) tool - xsd.exe doesn't generate types when they are not used inside any element. e.g. XSD File (I threw in the complex element to avoid this warning - "Warning: cannot generate classes because no top-level elements with complex type were found."): <?xml version="1.0" encoding="utf-8"?> <xs:schema targetNamespace="http://tempuri.org/XMLSchema.xsd" elementFormDefault="qualified" xmlns="http://tempuri.org/XMLSchema.xsd" xmlns:mstns="http://tempuri.org/XMLSchema.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" > <xs:simpleType name="EnumTest"> <xs:restriction base="xs:string"> <xs:enumeration value="item1" /> <xs:enumeration value="item2" /> <xs:enumeration value="item3" /> </xs:restriction> </xs:simpleType> <xs:complexType name="myComplexType"> <xs:attribute name="Name" use="required" type="xs:string"/> </xs:complexType> <xs:element name="myElem" type="myComplexType"></xs:element> </xs:schema> When i run this thru xsd.exe using xsd /c xsdfile.xsd I don't see EnumTest in the generated cs file. Note; Even though I don't use the enum here, but in my actual project, I have cases like this where we send enum's string value as output. How can I force the xsd tool to include these? Or should I switch to some other tool? I work in Visual Studio 2008.

• LINQ XML query at c# wp7

  - by Karloss

  I am working at Windows Phone 7 C#, Xaml, XML and LINQ programming. I need to organize search by part of the name at following XML: <Row> <Myday>23</Myday> <Mymonth>12</Mymonth> <Mynames>Alex, Joanna, Jim</Mynames> </Row> <Row> <Myday>24</Myday> <Mymonth>12</Mymonth> <Mynames>John, David</Mynames> </Row> I have following query: var myData = from query in loadedData.Descendants("Row") where query.Element("Mynames").Value.Contains("Jo") select new Kalendars { Myday = (int)query.Element("Myday"), Mymonth = (int)query.Element("Mymonth"), Mynames = (string)query.Element("Mynames") }; listBoxSearch.ItemsSource = myData; Query problem is, that it will return full part of the names like "Alex, Joanna, Jim" and "John, David". How can i get only Joanna and John? Second question is how it is possible to do that user enters ...Value.Contains("jo") and query still returns Joanna and John? Possible solution (needs some corrections) public string Search_names { get { return search_names; } set { string line = this.Mynames; string[] names = line.Split(new[] { ", " }, StringSplitOptions.None); var jos = from name in names where name.Contains("is") select name; // ["Joanna"] // HOW TO BIND search_names? } }

  I am new to Hibernate. I have an exception while running an Hibernate-based application.
