reading value from xml

I have a config file(xml document) which contains only one line of data i.e <id>8888</id>

In my installer I have to read the value of this id i.e 8888.
id value can have 4-6 digits.

Could u pls let me know how to do this is nsis? or refer me to the manuals or any related documents.

Or, if you're really sure it only contains one line, you can simply use FileOpen->FileRead->FileClose, and then use StrCpy to remove the first 4 and last 5 bytes.
