[RESOLVED] Rss + xsd + php

Hi,

I am in need of validating a RSS file which is generated by a program and so I developed a XSD schema and tried to validate a RSS file with that using DOM.

It didn’t work not sure whether my schema is not valid, I have posted in XML section [URL=”http://www.webdeveloper.com/forum/showthread.php?p=961142#post961142″]http://www.webdeveloper.com/forum/showthread.php?p=961142#post961142[/URL] , and my question is, is my approach to validate RSS via PHP is correct.

Also are there any alternatives to validate a RSS feed.

PHP File

[code=php]<?php
$xdoc = new DomDocument;
$xmlfile = ‘xml/rss.xml’;
$xmlschema = ‘xml/rss.xsd’;
//Load the xml document in the DOMDocument object
$xdoc->Load($xmlfile);
//Validate the XML file against the schema
if ($xdoc->schemaValidate($xmlschema)) {
print “$xmlfile is valid.n”;
} else {
print “$xmlfile is invalid.n”;
}
?>[/code]
