What's wrong? I'm trying to match processing instructions. I want to get rid of the <?Eqn TeX input="\hskip -32pt\hbox to32pt{[6]}"?> part in the source file. Source file: <equation> and <inlineequation> mixed with text and markup. XSLT: I match every <equation> and <inlineequation> and copy recursively any attributes and elements. I match processing instructions and remove them all (but I want to keep some of them later). output: no processing instructions removed. Am I doing the right thing to match the processing instructions? See stylesheet below. Thanks.
