Trying to parse xml, but xmldocument.loadxml() is trying to download?

- by maxp

I have a string input that i do not know whether or not is valid xml. I think the simplest aprroach is to wrap new XmlDocument().LoadXml(strINPUT); In a try/catch. The problem im facing is, sometimes strINPUT is an html file, if the header of this file contains <!DOCTYPE html PUBLIC ""-//W3C//DTD XHTML 1.0 Transitional//EN"" ""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd""> <html xml:lang=""en-GB"" xmlns=""http://www.w3.org/1999/xhtml"" lang=""en-GB""> ...like many do, it actually tries to make a connection to the w3.org url, which i really dont want it doing. Anyone know if its possible to just parse the string without trying to be clever and checking external urls? Failing that is there an alternative to xmldocument?

Is there any better way for creating a dynamic HTML table without using any javascript library like

- by piemesons

Dont worry we dont need to find out any bug in this code.. Its working perfectly.:-P My boss came to me and said "Hey just tell me whats the best of way of writing code for a dynamic HTML table (add row, delete row, update row).No need to add any CSS. Just javascript. No Jquery library etc. I was confused that in the middle of the project why he asking for some stupid exercise like this. What ever i wrote the following code and mailed him and after 15 mins i got a mail from him. " I was expecting much better code from a guy like you. Anyways good job monkey.(And with a picture of monkey as attachment.) thats was the mail. Line by line. I want to reply him but before that i want to know about the quality of my code. Is this really shitty...!!! Or he was just making fun of mine. I dont think that code is really shitty. Still correct me if you can.Code is working perfectly fine. Just copy paste it in a HTML file. <html> <head> <title> Exercise CSS </title> <script type="text/javascript"> function add_row() { var table = document.getElementById('table'); var rowCount = table.rows.length; var row = table.insertRow(rowCount); var cell1 = row.insertCell(0); var element1 = document.createElement("input"); element1.type = "text"; cell1.appendChild(element1); var cell2 = row.insertCell(1); var element2 = document.createElement("input"); element2.type = "text"; cell2.appendChild(element2); var cell3 = row.insertCell(2); cell3.innerHTML = ' <span onClick="edit(this)">Edit</span>/<span onClick="delete_row(this)">Delete</span>'; cell3.setAttribute("style", "display:none;"); var cell4 = row.insertCell(3); cell4.innerHTML = '<span onClick="save(this)">Save</span>'; } function save(e) { var elTableCells = e.parentNode.parentNode.getElementsByTagName("td"); elTableCells[0].innerHTML=elTableCells[0].firstChild.value; elTableCells[1].innerHTML=elTableCells[1].firstChild.value; elTableCells[2].setAttribute("style", "display:block;"); elTableCells[3].setAttribute("style", "display:none;"); } function edit(e) { var elTableCells = e.parentNode.parentNode.getElementsByTagName("td"); elTableCells[0].innerHTML='<input type="text" value="'+elTableCells[0].innerHTML+'">'; elTableCells[1].innerHTML='<input type="text" value="'+elTableCells[1].innerHTML+'">'; elTableCells[2].setAttribute("style", "display:none;"); elTableCells[3].setAttribute("style", "display:block;"); } function delete_row(e) { e.parentNode.parentNode.parentNode.removeChild(e.parentNode.parentNode); } </script> </head> <body > <div id="display"> <table id='table'> <tr id='id'> <td> Piemesons </td> <td> 23 </td> <td > <span onClick="edit(this)">Edit</span>/<span onClick="delete_row(this)">Delete</span> </td> <td style="display:none;"> <span onClick="save(this)">Save</span> </td> </tr> </table> <input type="button" value="Add new row" onClick="add_row();" /> </div> </body>

Multiple CSS Classes: Properties Overlapping based on the order defined.

- by Jian Lin

Is there a rule in CSS that determines the cascading order when multiple classes are defined on an element? (class="one two" vs class="two one") Right now, there seems to be no such effect. Example: both divs are orange in color on Firefox <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <style> .one { border: 6px dashed green } .two { border: 6px dashed orange } </style> </head> <body> <div class="one two"> hello world </div> <div class="two one"> hello world </div>

In Flex, how do i create a summary(say total of various domains) from the data provider and display in chart? Say this is my dataprovider..

How to generate makefile targets from variables?

- by Ketil

I currently have a makefile to process some data. The makefile gets the inputs to the data processing by sourcing a CONFIG file, which defines the input data in a variable. Currently, I symlink the input files to a local directory, i.e. the makefile contains: tmp/%.txt: tmp ln -fs $(shell echo $(INPUTS) | tr ' ' '\n' | grep $(patsubst tmp/%,%,$@)) $@ This is not terribly elegant, but appears to work. Is there a better way? Basically, given INPUTS = /foo/bar.txt /zot/snarf.txt I would like to be able to have e.g. %.out: %.txt some command As well as targets to merge results depending on all $(INPUT) files. Also, apart from the kludgosity, the makefile doesn't work correctly with -j, something that is crucial for the analysis to complete in reasonable time. I guess that's a bug in GNU make, but any hints welcome.

Css3 Transition on background transparent not working in Chrome 5

- by Ricardo Koch

I`m trying to create an animation using CSS3 transition. The animation is a gradient background that should change his color (rgba). I used the webkit tag for the gradient and it`s working in Chrome 5.0.375.55. Looking into w3c site I see that "background-image - only gradients" is supported for the transition. (http://www.w3.org/TR/css3-transitions/) But I can only animate the background-color property with this version of chrome. With gradient the transition does not work. Does anyone managed to create an animation with background gradients?

Finding nth-child of siblings via jQuery

- by DA

Let's say I have two tables that look like this: TH TH TH TH TD TD TD TD TD TD TD TD and TH TH TH TH TH TD TD TD TH TD TD TD I'd like to select the 3rd column in each. At first I was using nth-child as such: $('table tr td:nth-child(3)') But that's not going to work, as 3rd TD is in a different column in each table. What I need in pseudo code is 'get the 3rd TD or TH in each row'. I assume I need to use $.siblings but not entirely sure.

last-child CSS issues

- by Neurofluxation

Hey you guys (and girls), I have implemented the following CSS: #tab-navigation ul li:last-child { background-image: url(../images/tabs-end.gif); background-repeat: no-repeat; color: #fff; display: block; border: 1px solid red; background-position: right; } However, for some reason this is not working at all in IE (surprise!) - I read (after some research) that IE requires a DOCTYPE, but I already have <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> defined. Any ideas peeps?

W3 Validation errors..

- by Kyle Sevenoaks

I have 12 errors, but some are just pure non existent. Doctype: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> Here's the error report, but the "duplicate specification of attribute "value"" simply isn't true according to my .tpl: {textfield class="quetext" value="Epost*" onblur="if(this.value=='') this.value='Epost*';" onfocus="if(this.value=='Epost*') this.value='';"} Also, does a textarea require the attribute "rows" and "cols"? I thought that was only for tables? And I don't understand what the two errors at the end mean: Line 586, Column 80: Attribute value redefined... Please help! Thanks :) (Sorry if things chop and change, I'm working on the valdiation now, to tidy up as many errors as possible.)

What is happening though is that when I move onto the language list, and I go past Germany (~50% down the list?), the hover() loses focus and closes the original menu, which closes the language menu. Any idea's what is causing the issue? Any ideas how to fix the issue? I have tried the hoverIntent() plugin as well to no avail.

Scrapy Not Returning Additonal Info from Scraped Link in Item via Request Callback

- by zoonosis

Basically the code below scrapes the first 5 items of a table. One of the fields is another href and clicking on that href provides more info which I want to collect and add to the original item. So parse is supposed to pass the semi populated item to parse_next_page which then scrapes the next bit and should return the completed item back to parse Running the code below only returns the info collected in parse If I change the return items to return request I get a completed item with all 3 "things" but I only get 1 of the rows, not all 5. Im sure its something simple, I just can't see it. class ThingSpider(BaseSpider): name = "thing" allowed_domains = ["somepage.com"] start_urls = [ "http://www.somepage.com" ] def parse(self, response): hxs = HtmlXPathSelector(response) items = [] for x in range (1,6): item = ScrapyItem() str_selector = '//tr[@name="row{0}"]'.format(x) item['thing1'] = hxs.select(str_selector")]/a/text()').extract() item['thing2'] = hxs.select(str_selector")]/a/@href').extract() print 'hello' request = Request("www.nextpage.com", callback=self.parse_next_page,meta={'item':item}) print 'hello2' request.meta['item'] = item items.append(item) return items def parse_next_page(self, response): print 'stuff' hxs = HtmlXPathSelector(response) item = response.meta['item'] item['thing3'] = hxs.select('//div/ul/li[1]/span[2]/text()').extract() return item

CDI @Conversation not propagated with handleNavigation()

- by Thomas Kernstock

I have a problem with the propagation of a long runnig conversation when I redirect the view by the handleNavigation() method. Here is my test code: I have a conversationscoped bean and two views: conversationStart.xhtml is called in Browser with URL http://localhost/tests/conversationStart.jsf?paramTestId=ParameterInUrl <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core"> <f:metadata> <f:viewParam name="paramTestId" value="#{conversationTest.fieldTestId}" /> <f:event type="preRenderView" listener="#{conversationTest.preRenderView}" /> </f:metadata> <h:head> <title>Conversation Test</title> </h:head> <h:body> <h:form> <h2>Startpage Test Conversation with Redirect</h2> <h:messages /> <h:outputText value="Testparameter: #{conversationTest.fieldTestId}"/><br /> <h:outputText value="Logged In: #{conversationTest.loggedIn}"/><br /> <h:outputText value="Conversation ID: #{conversationTest.convID}"/><br /> <h:outputText value="Conversation Transient: #{conversationTest.convTransient}"/><br /> <h:commandButton action="#{conversationTest.startLogin}" value="Login ->" rendered="#{conversationTest.loggedIn==false}" /><br /> <h:commandLink action="/tests/conversationLogin.xhtml?faces-redirect=true" value="Login ->" rendered="#{conversationTest.loggedIn==false}" /><br /> </h:form> <h:link outcome="/tests/conversationLogin.xhtml" value="Login Link" rendered="#{conversationTest.loggedIn==false}"> <f:param name="cid" value="#{conversationTest.convID}"></f:param> </h:link> </h:body> </html> The Parameter is written to the beanfield and displayed in the view correctly. There are 3 different possibilites to navigate to the next View. All 3 work fine. The beanfield shows up the next view (conversationLogin.xhtml) too: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core"> <h:head> <title>Conversation Test</title> </h:head> <h:body> <h:form> <h2>Loginpage Test Conversation with Redirect</h2> <h:messages /> <h:outputText value="Testparameter: #{conversationTest.fieldTestId}"/><br /> <h:outputText value="Logged In: #{conversationTest.loggedIn}"/><br /> <h:outputText value="Conversation ID: #{conversationTest.convID}"/><br /> <h:outputText value="Conversation Transient: #{conversationTest.convTransient}"/><br /> <h:commandButton action="#{conversationTest.login}" value="Login And Return" /><br /> </h:form> </h:body> </html> When I return to the Startpage by clicking the button the conversation bean still contains all values. So everything is fine. Here is the bean: package test; import java.io.Serializable; import javax.annotation.PostConstruct; import javax.enterprise.context.Conversation; import javax.enterprise.context.ConversationScoped; import javax.faces.event.ComponentSystemEvent; import javax.inject.Inject; import javax.inject.Named; @Named @ConversationScoped public class ConversationTest implements Serializable{ private static final long serialVersionUID = 1L; final String CONVERSATION_NAME="longRun"; @Inject Conversation conversation; private boolean loggedIn; private String fieldTestId; @PostConstruct public void init(){ if(conversation.isTransient()){ conversation.begin(CONVERSATION_NAME); System.out.println("New Conversation started"); } loggedIn=false; } public String getConvID(){ return conversation.getId(); } public boolean isConvTransient(){ return conversation.isTransient(); } public boolean getLoggedIn(){ return loggedIn; } public String startLogin(){ return "/tests/conversationLogin.xhtml?faces-redirect=true"; } public String login(){ loggedIn=true; return "/tests/conversationStart.xhtml?faces-redirect=true"; } public void preRenderView(ComponentSystemEvent ev) { // if(!loggedIn){ // System.out.println("Will redirect to Login"); // FacesContext ctx = FacesContext.getCurrentInstance(); // ctx.getApplication().getNavigationHandler().handleNavigation(ctx, null, "/tests/conversationLogin.xhtml?faces-redirect=true"); // ctx.renderResponse(); // } } public void setFieldTestId(String fieldTestId) { System.out.println("fieldTestID was set to: "+fieldTestId); this.fieldTestId = fieldTestId; } public String getFieldTestId() { return fieldTestId; } } Now comes the problem !! As soon as I try to redirect the page in the preRenderView method of the bean (just uncomment the code in the method), using handleNavigation() the bean is created again in the next view instead of using the allready created instance. Although the cid parameter is propagated to the next view ! Has anybody an idea what's wrong ? best regards Thomas

The problem is only with unchecked boxes. I mean, when you check some checkboxes it sends it as true (and that's right) but when i uncheck them it remains the same (true).

how do I use html block snippets with dynamic content inside a django template that extends another

Hi. Can someone please help me figure out a way to achieve the following (see snippets below) in Django templates? I know that you cannot use more than one extends, but I am new to django and I do not know the proper syntax for something like this. I want to be able to do this so that I can use my nested div layout for css reasons without having to type it like that each time and risking a typo.

I can only find implementations for Kruskal's Algorithm and Prim's Algorithm both of which will only return a single MST. I've seen papers that address this problem (such as http://fano.ics.uci.edu/cites/Publication/Epp-TR-95-50.html) but my head tends to explode someway through trying to think how to translate it to code. In fact i've not been able to find an implementation in any language!

Invalid argument for foreach()

- by johnny-kessel

Error I'm receiving Invalid argument supplied for foreach() The offending portions is this: foreach($subs[$id] as $id2 => $data2) Strange cause I'm using the same construct elsewhere and it works fine.. I'm using it to generate sub-categories and it works but I want to get rid of the error This is more context foreach($parents as $id => $data) { if($x == 0) { $html .= "<tr width='25%' class='row2'>"; } $shtml = ""; $i = 0; ***foreach($subs[$id] as $id2 => $data2)*** { $i++; if($i == 15) { $shtml .= $this->ipsclass->compiled_templates[ 'skin_businesses' ]->portal_categories_sub_row( $id2, $data2['cat_name'], 1 ) . ""; break; } else $shtml .= $this->ipsclass->compiled_templates[ 'skin_businesses' ]->portal_categories_sub_row( $id2, $data2['cat_name'], 0 ) . ""; }

Bash Scripting: I want to open a set of .php files, and add line before html tag

- by Bashn00b

Hi guys, I have a set of .php files in a folder, I want to add text just before these lines: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en" > What i want is to insert just before these lines in the html file. So just want to prepend that file before each docType declaration. However the DOCTYPE declaration is never on line 1, as there is loads of php lines before. I have this current script (where FE is the folder containing all the scripts i want to edit): for file in ${fe}*; do echo "$file" done Thanks,
