I have in a document, d:link - for both links to other text in the
document (e.g. link to a figure) as well as links to URLs. For both
types of links I am using d:link. I would like the following code to
select only those instances where the @linkend contains the string
'http' - and to then put angle brackets before and after those URLs. The
if:test syntax under variable "content" is obviously wrong - what is the
correct syntax for selecting linkends that are only URLs?
Thanks
<xsl:template match="d:link" name="link">
<xsl:param name="linkend" select="@linkend"/>
<xsl:param name="targets" select="key('id',$linkend)"/>
<xsl:param name="target" select="$targets[1]"/>
<xsl:variable name="xrefstyle">
<xsl:choose>
<xsl:when test="@role and not(@xrefstyle)
and $use.role.as.xrefstyle != 0">
<xsl:value-of select="@role"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="@xrefstyle"/>
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<xsl:variable name="content">
<xsl:if test="contains(linkend,'http')">
<xsl:value-of select="$puncbeforeurl"/>
</xsl:if>
<!--<xsl:if test="ancestor::d:bibliomixed or ancestor::d:bibliography">
