How can I parse Javascript using Xpath?

Question

I am trying to parse the html pages using php xpath, there are some data that are inserted into html through javascript, for example

<script type="text/javascript">     
   var insertName = function() {                
       var firstName = 'Hi SomeUserName';
       $('#welcomeMessage').html(firstName)
   }
</script>
<h1 id="welcomeMessage"></h1>

I want to extract the data 'hi SomeUserName' alone.

Is it possible to do this in php xpath? or is there a best way to do this?

You can use jParser - A JavaScript parsing library for PHP for parsing JavaScript code inside <script> tag. And to get <script> tag, DOMDocument or any other HTML parser can be used.

thanks for the information!, i just tried jparser, its first converting javascript to xml and i have to parse the xml again, though it gives a way to parse javascript its making the job more cumbersome in think, i am now using the normal string functions of php to get the required text.
