Re: [docbook-apps] Checking for different types of links (xref vs link/linkend vs link/href)

[Bob Stayton <bobs@sagehill.net>]

Hi Janice,
Regarding your customization, are you using DocBook 5?  If so, then the 
element name needs a d: namespace prefix in front of it.

<xsl:when test="self::d:xref">blue</xsl:when>

You also mentioned wanting link/href links to have blue, so that would be:

test="self::d:link[@xlink:href]"

Regarding olinks not working in webhelp, I believe that was fixed.  See 
the last comment in this bug report:
