Re: Attribute value quoting with Saxon8

2005-08-20 02:45:29
I hoped this would be an error on user side so that I could fix this fast.
I thought that only double qoutes could embed singels qoutes and not otherwise around.

The problem I encounter here is that I could have something like <input onclick="<% get_action("submit"); %>" /> . If "<% get_action("submit"); %>" returns something like "alert('Please check value!');" this works with double qoutes but would be problematic with single qoutes.

Is there is an option to change this behaviour?

Kindest regards,
Victor

Saxon is trying to be helpful here; if you generate an attribute value
containing double quotes, it uses single quotes as the delimiter to try and
make it valid XML/HTML if it can. Is this output really being passed to
software that requires double quotes around the attribute value? If so, I'm
afraid the only solution is to generate the whole start tag "by hand".

Subject: [xsl] Attribute value quoting with Saxon8

I am trying to change some web pages for an embbeded device from ancient
HTML to XML which should ease changes of the resulting pages.
The resulting pages will be _not_ valid HTML because they are parsed by
the HTTP server of the device and then the hopefully valid result will
be returned to the browser.

However I have some trouble to create attributes which values are in
double qoutes if the value itself contains double qoutes.

My environment:
     JDK 1.5.0_04 (on WinXP)
     Saxon-B 8.5

Any help is greatly appreciated.

Kindest regards,
Victor
