Re: emacspeak-w3-xslt-filter The State of Web Browsing in Emacspeak [very long]

["T. V. Raman" <raman@xxxxxxxxxxx>]

I myself haven't run into trouble with w3 applying css -- since I
had the wrapper advice around the css parser in my environment
(now checked in in emacspeak-w3).

If there is some other reason to strip out CSS bits from a page
before handing it to w3, writing a strip-style.xsl should be
trivial and is left as an exercise to the reader.

An XPath tutorial is again outside the scope of Emacspeak docs,
but you might want to write a short section as a means of
teaching it to yourself.
