I edit/write/manipulate a lot of XML files and I'd like to create a simple way to use XPath for searching/selecting in the current document. Ideally, I'd open a textfield akin to the "Incremental Search" (CTRL+S) field and just write the expression, hit enter and the results would open in a "Web Preview" window.
I can get the durrent document's contents and do the XPath stuff, but I don't know how to hi-jack (if at all possible) the Incremental Search bar, or create something that worked similar.
Any clues for how to approach that?
An alternative way would be to just open a $DIALOG, asking for the XPath expression and then do the processing - but I can't see a $DIALOG command that lets me do that (read input)...

Hi Chriztian,
well, if you want to come up with the result in an HTML window then I'd go with BASH/Perl/Ruby/Python/... + HTML+JavaScript, i.e. create a tmcommand which creates an HTML page containing an INPUT field, the JS onChange event of that INPUT field triggers a JS function which take the XPATH, validates it and applies it to the document (use TextMate.system() JS-to-TM/BASH-bridge) and show the result, maybe via AXAJ injection, within the HTML window.
Cheers, --Hans

Using the ruby UI wrapper (for DIALOG), such command could take the following form:
#!/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -wKU require "#{ENV['TM_SUPPORT_PATH']}/lib/exit_codes" require "#{ENV['TM_SUPPORT_PATH']}/lib/ui"
query = TextMate::UI.request_string(:prompt => "XPath Query:") TextMate.exit_discard if query.to_s.empty?
# output HTML based on stdin and query…
You can mix this with the suggestion by Hans-Jörg, i.e. let the generated HTML include a text field prepopulated with the query string, allowing the user to change the query.
If so, you may want to allow an initial empty query string, for that, change ‘query.to_s.empty?’ → ‘query.nil?’ in the above. This will still allow the user to abort the command (and never see the HTML output window) via the Cancel button (or ⌘,) but if they just press return, the window will appear.
