  • Xerces SAX parser ignore the xmlxs:xsi attribute as an attribute of an element

    - by user603301
    Hi, Using Xerces SAX parser I try to retrieve all elements and their attributes of this XML file: -------------- Begin XML file to parse ---------------- <?xml version="1.0" encoding="UTF-8"?> <invoice xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="my.xsd"> <parties> (...) -------------- End XML file to parse ---------------- When getting the attributes for the element 'invoice', Xerces++ does not insert the 'xmlns:xsi' attribute in the list of 'Attributes' for the element 'invoice'. However, the attribute 'xsi:noNamespaceSchemaLocation' is inserted in the list. Why? Is there a specific reason from an XML standard point of view ? Is there a way to configure Xerces++ SAX parser so that it inserts this attribute as well? (The documentation on setting the parser properties does not tell how). Thanks for your help.

  • Using generics to make an algorithm work on lists of "something" instead of only String's

    - by Binary255
    Hi, I have a small algorithm which replaces the position of characters in a String: class Program { static void Main(string[] args) { String pairSwitchedStr = pairSwitch("some short sentence"); Console.WriteLine(pairSwitchedStr); Console.ReadKey(); } private static String pairSwitch(String str) { StringBuilder pairSwitchedStringBuilder = new StringBuilder(); for (int position = 0; position + 1 < str.Length; position += 2) { pairSwitchedStringBuilder.Append((char)str[position + 1]); pairSwitchedStringBuilder.Append((char)str[position]); } return pairSwitchedStringBuilder.ToString(); } } I would like to make it as generic as possible, possibly using Generics. What I'd like to have is something which works with: Anything that is built up using a list of instances. Including strings, arrays, linked lists I suspect that the solution must use generics as the algorithm is working on a list of instances of T (there T is ... something). Version of C# isn't of interest, I guess the solution will be nicer if features from C# version 2.0 is used.

  • Binding a date string parameter in an MS Access PDO query

    - by harryg
    I've made a PDO database class which I use to run queries on an MS Access database. When querying using a date condition, as is common in SQL, dates are passed as a string. Access usually expects the date to be surrounded in hashes however. E.g. SELECT transactions.amount FROM transactions WHERE transactions.date = #2013-05-25#; If I where to run this query using PDO I might do the following. //instatiate pdo connection etc... resulting in a $db object $stmt = $db->prepare('SELECT transactions.amount FROM transactions WHERE transactions.date = #:mydate#;'); //prepare the query $stmt->bindValue('mydate', '2013-05-25', PDO::PARAM_STR); //bind the date as a string $stmt->execute(); //run it $result = $stmt->fetch(); //get the results As far as my understanding goes the statement that results from the above would look like this as binding a string results in it being surrounded by quotes: SELECT transactions.amount FROM transactions WHERE transactions.date = #'2013-05-25'#; This causes an error and prevents the statement from running. What's the best way to bind a date string in PDO without causing this error? I'm currently resorting to sprintf-ing the string which I'm sure is bad practise. Edit: if I pass the hash-surrounded date then I still get the error as below: Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[22018]: Invalid character value for cast specification: -3030 [Microsoft][ODBC Microsoft Access Driver] Data type mismatch in criteria expression. (SQLExecute[-3030] at ext\pdo_odbc\odbc_stmt.c:254)' in C:\xampp\htdocs\ips\php\classes.php:49 Stack trace: #0 C:\xampp\htdocs\ips\php\classes.php(49): PDOStatement-execute() #1 C:\xampp\htdocs\ips\php\classes.php(52): database-execute() #2 C:\xampp\htdocs\ips\try2.php(12): database-resultset() #3 {main} thrown in C:\xampp\htdocs\ips\php\classes.php on line 49

  • Problem with eastern european characters when scraping data from the European Parliaments Website

    - by Thomas Jensen
    Dear Experts I am trying to scrape a lot of data from the European Parliament website for a research project. Ther first step is the create a list if all parliamentarians, however due to the many Eastern European names and the accents they use i get a lot of missing entries. Here is an example of what is giving me troubles (notice the accents at the end of the family name): ANDRIKIENE, Laima Liucija Group of the European People's Party (Christian Democrats) So far I have been using PyParser and the following code: parser_names name = Word(alphanums + alphas8bit) begin, end = map(Suppress, "<") names = begin + ZeroOrMore(name) + "," + ZeroOrMore(name) + end for name in names.searchString(page): print(name) However this does not catch the name from the html above. Any advice in how to proceed? Best, Thomas

  • Extracting email addresses in an html block in ruby/rails

    - by corroded
    I am creating a parser that wards off against spamming and harvesting of emails from a block of text that comes from tinyMCE (so it may or may not have html tags in it) I've tried regexes and so far this has been successful: /\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b/i problem is, i need to ignore all email addresses with mailto hrefs. for example: <a href="mailto:[email protected]">[email protected]</a> should only return the second email add. To get a background of what im doing, im reversing the email addresses in a block so the above example would look like this: <a href="mailto:[email protected]">moc.liam@tset</a> problem with my current regex is that it also replaces the one in href. Is there a way for me to do this with a single regex? Or do i have to check for one then the other? Is there a way for me to do this just by using gsub or do I have to use some nokogiri/hpricot magicks and whatnot to parse the mailtos? Thanks in advance! Here were my references btw: so.com/questions/504860/extract-email-addresses-from-a-block-of-text so.com/questions/1376149/regexp-for-extracting-a-mailto-address im also testing using this: http://rubular.com/ edit here's my current helper code: def email_obfuscator(text) text.gsub(/\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b/i) { |m| m = "<span class='anti-spam'>#{m.reverse}</span>" } end which results in this: <a target="_self" href="mailto:<span class='anti-spam'>moc.liamg@tset</span>"><span class="anti-spam">moc.liamg@tset</span></a>

    - by Mani
    I tried the example given in http://forums.sun.com/thread.jspa?threadID=780576&tstart=67605 to create if statement dynamically. But it is not working fine. Instead of using "age" variable as integer, i have used string in the below example. I am getting "fail" as answer instead of "success". Can anyone help me? / To change this template, choose Tools | Templates and open the template in the editor. / import java.lang.reflect.*; import bsh.Interpreter; public class Main { public static String d; public static void main(String args[]) { try { String age = "30"; String cond = "age==30"; Interpreter i = new Interpreter(); i.set("age", age); System.out.println(" sss" + i.get("age")); if((Boolean)i.eval(cond)) { System.out.println("success"); } else { System.out.println("fail"); } } catch (Throwable e) { System.err.println(e); } } } Thanks, Mani

  • Accessing items separated by -componentsSeparatedByString

    - by Graeme
    Hi, I have an array gathered by componentsSeparatedByString: that looks like the following when I use po in the GDB after the array has gone through componentsSeparatedByString: "\n\t\t <b>Suburb, </b> BAIRNSDALE", "\n\t\t <b>Address, </b> 15K NW BAIRNSDALE", "\n\t\t <b>Reference, </b> MELWOOD/SCHOOL ROAD", "\n\t\t <b>Last Changed, </b> 09/04/10 05, 29, 00 PM", "\n\t\t <b>Type, </b> HOME", "\n\t\t <b>Status, </b> BUILT", "\n\t\t <b>Property Size, </b> 2.00 HA.", "\n\t\t <b>Residents, </b> 2", "\n\t\t <b>First Added Date/Time, </b> 09/04/10 03, 15, 00 PM", "\n\t\t\t" Only problem is, I now can't figure out where to go from here. I need to be able to access each of these items (i.e. type, status, property size) separately rather than just calling the entire array (i.e. currentProperty.status). How do I do this? Also what's with all the n\t\t\t things - how do I get rid of them? Thanks.

  • boost::Spirit Grammar for unsorted schema

    - by Hassan Syed
    I have a section of a schema for a model that I need to parse. Lets say it looks like the following. { type = "Standard"; hostname="x.y.z"; port="123"; } The properties are: The elements may appear unordered. All elements that are part of the schema must appear, and no other. All of the elements' synthesised attributes go into a struct. (optional) The schema might in the future depend on the type field -- i.e., different fields based on type -- however I am not concerned about this at the moment.

  • pyparsing ambiguity

    - by Claudiu
    I'm trying to parse some text using PyParser. The problem is that I have names that can contain white spaces. So my input might look like this: Joe Bob Jimmy Foo Joe decides to eat. Bob decides to not eat. Jimmy Foo decides to eat. How can I create a parser for the decides to eat line? If I create my name parser naively, meaning with alphabetic characters plus space characters, then it will match the entire line.

  • How to extract paragaph and selected lines with Perl

    - by neversaint
    I have a text that looks like this. What I want to do is to extract the whole paragraph under the section "Aceview summary" until the line that starts with "Please quote". extract the line that starts with "The closest human gene". And store them into array with two elements. However I am stuck with the following script logic. What's the right way to achieve that? #!/usr/bin/perl -w my $INFILE_file_name = $file; # input file name open ( INFILE, '<', $INFILE_file_name ) or croak "$0 : failed to open input file $INFILE_file_name : $!\n"; my @allsum; while ( <INFILE> ) { chomp; my $line = $_; my @temp1 = (); if ( $line =~ /^ AceView summary/ ) { print "$line\n"; push @temp1, $line; } elsif( $line =~ /Please quote/) { push @allsum, [@temp1]; @temp1 = (); } } close ( INFILE ); # close input file

  • Use LINQ and lambdas to put string in proper case

    - by Tobias Funke
    I have this function called ProperCase that takes a string, then converts the first letter in each word to uppercase. So ProperCase("john smith") will return "John Smith". Here is the code: public string ProperCase(string input) { var retVal = string.Empty; var words = input.Split(' '); foreach (var word in words) { if (word.Length == 1) { retVal += word.ToUpper(); } else if (word.Length > 1) { retVal += word.Substring(0, 1).ToUpper() + word.Substring(1).ToLower(); } retVal += ' '; } if (retVal.Length > 0) { retVal = retVal.Substring(0, retVal.Length - 1); } return retVal; } This code workds perfectly, but I'm pretty sure I can do it more elegantly with LINQ and lambdas. Can some please show me how?

  • How do Relational Databases Work Under the Hood?

    - by Pierreten
    I've always been interested in how you can throw some SQL at at database, and it nearly instantaneously returns your results in an orderly manner without thinking about it as anything other than a black box. What is really going on? I'm pretty sure it has something to do with how values are laid out regularly in memory, similar to an array; but aside from that, I don't know much else. How is SQL parsed in a manner to facilitate all of this?
