如何使用Xpath解析Javascript？

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.
