I have a problem parsing/mapping a xml response from a API.

I would like to get the id numer of a keyword when the keyword.text is  
like ‘Engels’

So i would like search in the xml response for the text ‘Engels’ than  
i would like to have the ‘href’ that belongs to that keyword. In this  
case [http://www.wrts.nl/api/keywords/84576](http://www.wrts.nl/api/keywords/84576), i actually only need the  
id numer because than i can make a new request to the api with that  
information.

The xml-response looks like this:

\<?xml version=\"1.0\" encoding=\"UTF-8\"?\>\n\n

\<keyword href="[http://www.wrts.nl/api/keywords/83212\](http://www.wrts.nl/api/keywords/83212%5C)“\>Duits

How should i do this? Do i need to parse the xml first, or is there a  
way to search in the xml directly?

Thank you in advance,
