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 http://www.webdeveloper.com/forum/sh...142#post961142 , 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
PHP Code:
<?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";
}
?>
