Multiple conditions on child node selection

Hi Experts,

I need some help formulating an XSL template that will output what I need from the attached XML file.

For each <tsfile> I need to locate the last <p> which has <id>[2] = 0.
Then return all <p>'s after the above position()

I've had a go, but I'm still learning XSLT and not having much luck.

Thanks
