Re: [docbook-apps] long alt text

["Bob Stayton" <bobs@sagehill.net>]

One could consider this to be a bug in the stylesheet.  At the point where
the phrase is processed into an alt attribute value, I think the
normalize-space() function should be applied to it.  I can't see any reason
to keep extra white space in an attribute value such as alt.

If you want to fix this yourself, copy the template named
'process.image.attributes' from html/graphics.xsl to your customization
layer and change this:

      <xsl:value-of select="$alt"/>

to this:

      <xsl:value-of select="normalize-space($alt)"/>

If no one objects, I'll make that change in the source.

Hello docbook-apps,

Markup like the following

        <mediaobject>
          <imageobject>
            <imagedata fileref="pr1/pr1_screenshot_2.png" />
          </imageobject>

          <textobject>
            <phrase>This diagram is a code flow chart for the Project 1
            routine for finding a bounded minimum.</phrase>
          </textobject>
        </mediaobject>

is producing

<div class="screenshot"><div class="mediaobject"><img
src="pr1/pr1_screenshot_2.png" alt="This diagram is a code flow chart
for the Project 1&#10;            routine for finding a bounded
minimum."/></div></div>

In longer alt texts, the "&#10;            " is appearing multiple
times. This appears to be related to the line wrapping that XXE
automatically applies to the source xml. So, uh, does anyone know a
way around this alt text problem?

from my Makefile:
XMLLINTOPTS=--xinclude --postvalid --noent --nonet

Thank you for your time,
