can xalan hypertext link urls in xml tags?
Hi everyone,
Given an XML file like this:
<Book>
<Title>Master Xalan the XSLT processor</Title>
<Summary>
Xalan is an XSLT processor for transforming XML documents into HTML, text, or other
XML document types. Xalan-Java version 1.2.D01 represents a complete and robust
reference implementation of the W3C Recommendations for XSL Transformations XSLT)
and the XML Path Language (XPath). See http://xml.apache.org/xalan for more
details.
</Summary>
</Book>
Is there some mechanism in Xalan to hypertext link urls found inside the
element tags? In the above example, I'd like to present the XML file in
HTML with the 'http://xml.apache.org/xalan' hypertext linked.
Someone mentioned sometime back the possibility of using templates and
string functions, but it is not obvious to me how this can be done.
This would appear to be a common thing, some I'm hoping there is already
something built into Xalan. Any suggestions, code, examples would be very
appreciated.
Chris

As I can see your <Link> template is correct. The summary could look like this:
<xsl:template match="Summary">
<pre>
<xsl:apply-templates/>
</pre>
</xsl:template>
That automatically calls templates for all text and element children of the
'Summary' element. (There is a default template for text which simply copies the
text.)

Hi Conny,
O.k. I'm trying your suggestion of using <Link> and creating an template. So for this
XML file:
<Book>
<Title>Master Xalan the XSLT processor</Title>
<Summary>
Xalan is an XSLT processor for transforming XML documents into HTML, text, or other
XML document types. Xalan-Java version 1.2.D01 represents a complete and robust
reference implementation of the W3C Recommendations for XSL Transformations XSLT)
and the XML Path Language (XPath). See <Link>http://xml.apache.org/xalan</Link> for
more details.
</Summary>
</Book>
I'm new to XSL so some help in getting my template working would be very appreciated.
I created two templates: Link and Summary.
<xsl:template match="Link">
<a>
<xsl:attribute name="href">
<xsl:value-of select="."/>
</xsl:attribute>
<xsl:value-of select="."/>
</a>
</xsl:template>
<xsl:template match="Summary">
<pre>
<xsl:apply-templates select="Link"/>
<xsl:value-of select="."/>
</pre>
</xsl:template>
This solution is obviously not correct because it applies the Link template first, then
prints ALL the summary information after that. What I want is to apply the link templates
inside the output of the Summary template? How can this be done?
Thanks,
Chris

Hi Chris,
I could imagine a template that extracts strings starting with 'http://' and
surrounds them with an <a> tag. Would require extensive usage of
'string-before()' and 'string-after()' functions and this may be someway slow.
I would recommend marking up the links with a <link> tag or something similar
and write a template for 'link'.
