Your example is confusing, because in standard DocBook, <row> does not
have "entry" attributes, only <entry> child elements.
But assuming you know that and this is really what you want, it sounds
like you are saying that you want to use the concatenated values of the
other attributes as the link ID. I think that you would do that not by
dynamically adding a "linkend" attribute, but by modifying the "xref"
template so that it retrieves the values of those other attributes
directly; something like this:
<xsl:variable name="linkID" select="@linkend" />
<xsl:choose>
<xsl:when test="id( $linkID )">
<xsl:call-template name="createURI">
<xsl:with-param name="element" select="id( $linkID )" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:call-template name="createURI">
<xsl:with-param name="element" select="*[concat(@entry1,
@entry2, @entry3) = $linkID]" />
</xsl:call-template>
</xsl:otherwise>
</xsl:choose>
You would have to make the entry text retrieval match the exact pattern
you want, but that's generally how I'd approach it.

Subject: A tricky xref problem
Hi all,
I wonder if there is a way to extract a text string and pass it as a
value for the <xref linkend=""/> expression. For example, when I write:
Some text text text (see ref=[sect_test]),
I would like to take the text within the [ ] delimiters and pass it as a
value for the linkend attribute of the xref element called in my
customized table template. The reason for this special workaround is
that I've created a custom template that enables you to add a table row
with its entries using one command, like so:
<table>
...
<row entry1="red" entry2="blue" entry3="black"/> -which saves a lot of
typing.
So, if I wish to add a reference to some section from within entry1, I
can't write:
<row entry1="red (refer to <xref linkend="sect_test"/>)" entry2="blue"
entry3="black"/>
I need somehow to customize my table template that says something like:
...
<xsl:for-each select="row">
<row>
<xsl:if test="$entry1">
<entry>
<xsl:value-of select="@entry1"/>
<xsl:if test="contains('xref')">
<xref>
<xsl:copy-of select="@*"/>
<xsl:attribute name="linkend">
<xsl:copy-of select="@*"/>
<xsl:value-of select="<extracted_text_string>"/>
</xsl:attribute>
</xref>
</xsl:if>
</entry>
</xsl:if>
...
</row>
</xsl:for-each>
...
Please, advise me how to extract the text string from within [ ]
delimiters to pass it as a value for the <xref> expression.
Thanks a lot in advance!!!
Best wishes,
Nancy
