XML : Searching XML String in Javascript/JQuery

I need a way to search through an XML String and return an array containing the "record" elements that meet multiple search criteria.

The structure is this:

    <record>       <project_name>Deploy Document Management</project_name>       <project_phase>Design</porject_phase>       <status>Not Started</status>       <priority>Medium</priority>   </record>   <record>       <project_name>Do Something Else</project_name>       <project_phase>Design</porject_phase>       <status>Not Started</status>       <priority>Medium</priority>       </record>    

If I wanted to return an array of "records" where status="Not Started" and priority = "Medium".... how would I do so using javascript or JQuery?

To be clear, I need the whole record for each record that matches the criteria.

Thanks in advance.
