xml string parsing

[Goose]

I have an xml string that I want to parse. I have read the w3schools xml tutorial and I still cannot figure all of this out. I want to do two things: Count the number elements in a given xml string (for a particular xml element) and access a particular value of an xml element. Here is an example of an xml string that I would be dealing with. Note, in my example there can be many <room> elements, many <message> elements and many <user> elements. Thanks in advance!

 

<room>

<name>Default</name>

<id>1</id>

<messages>

<message>

<usr>goose</usr>

<msg>Hello everyone!</msg>

</message>

<message>

<usr>goose</usr>

<msg>This is an XML example.</msg>

</message>

</messages>

<users>

<user>

<uid>1</uid>

<usr>goose</usr>

</user>

</users>

</room>

There must be a JS library for this...

Try out XML for <script> from Sourceforge.
