regular express issue

[dizyn]

I want to fetch value of msg element using regular expression. Please help

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<epp xmlns="urn:iana:xml:ns:epp-1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:iana:xml:ns:epp-1.0 epp-1.0.xsd">
    <result code="2400">
      <msg>Command fail</msg>
	  <value>mjdizyn.com</value>
    </result>
    <unspec/>
</epp>

I am using this code:

function startElement($parser, $name, $attrs)
{
    if($name == "MSG")
    {
        global $a;
        $a = 0;
    }
}
function endElement($parser, $name)
{
}
function characterData($parser, $name)
{
}
$xml_parser = xml_parser_create();
xml_set_element_handler($xml_parser, "startElement", "endElement");
xml_set_character_data_handler($xml_parser, "characterData");
//$fp = fopen($file, "r");
$data = $file; //fread($fp, 4096);
xml_parse($xml_parser, $data);
xml_parser_free($xml_parser);

The regex would be something like:

preg_match("/<msg>(.*?)<\/msg>/", $text, $matches); 

where $text is the data.
It returns an array of matches:

Array ( [0] => Command fail [1] => Command fail )

I have no experience using PHP's XML parser, but can't it be used for this exact purpose?

I am in a similar position as Raffles, so this is just speculation but doesn't the PHP XML parser support XPath experssions that would allow you to target the CDATA contained within any arbitrary element.
