searching a value from a string

hi guys
I have strings like this

String xmlfileLocation = "";
string xmldata =
"Id: 57A3 
Type: Buy 
Amount: $28 
<a href="http://www.bamboo.com/instit/R_0117_3.xml">XML version</a>

From the above string xmldata i want to extract the url value of xml file
so my final output would be
String xmlfileLocation = "http://www.bamboo.com/instit/R_0117_3.xml";
Any idea whats the best way to acchieve this ?

Shiould i convert the xmldata string to an XML object first?

any help will be greatly appreciated
thanks

Hello,

Firstly it must be a well formed XML document. Meaning there be one root element defined and every tag is closed..

I don't know about Java. However, in PHP i would extract the value using the code snippet below :

$data ="<?xml version='1.0' encoding='utf-8'?>
<root>
Id: 57A3
Type: Buy
Amount $28
<a href='http://www.bamboo.com/instit/R_0117_3.xml'>XML Versions</a>
</root>";
$xml = simplexml_load_string($data);
$children = $xml->xpath('/root/*');

foreach ($children as $test){
if($test == "XML Versions"){
$value = $test['href'];
break;
}
}
echo 'The url under the link tag is'.$value;

The $value would essentially contain the url. Hope this helps!!!
