relative paths with XPath in libxml2

Hi everyone!
I'm using libxml2 in linux and want to learn how to do it with xpath instead of manually traversing the tree. However, to make it useful I need to use relative path instead of having to start from the root all the time as with

Code:

---

result = xmlXPathEvalExpression(path, context);

---

This must be possible! Any input is wellcome!

Try googling for "libxml2 xpath relative path" or something similar. Or maybe guess the name. xmlXPathRelativeEvalExpression . . . .

I tried that off course! And XPath contains NO functions with 'Relative' in it. So... that won't cut it :(

I think you may have to maintain the relative path yourself and always pass the root to the function.
