Tricky XSL question (?)

J

Jyrki Keisala

I have an XML file:

<document>

<record>
<element1>Text</element1>
<element2>More text</element2>
<element3>Even more text</element3>
<element4>Some text <link><title>Google</title><url>
http://www.google.com</url></link> with a link.</element4>
</record>

<record>
<element1>Yeah</element1>
<element2>Now the link is here: <link><title>W3C</title><url>
http://www.w3c.org</url></link></element2>
<element3>Something else</element3>
<element4>...and more text</element4>
</record>

</document>

which I want to convert to an HTML table. One possibility for the
conversion is to use for-each loop in XSL as in

(XSL1)

<xsl:template match="/">
<html>
<head>
<title>My HTML table</title>
</head>
<body>
<table border="1">
<head>
<tr>
<td><b>Element1</b></td>
<td><b>Element2</b></td>
<td><b>Element3</b></td>
<td><b>Element4</b></td>
</tr>
</head>
<xsl:for-each select="document/record">
<tr>
<td><xsl:value-of select="element1" /></td>
<td><xsl:value-of select="element2" /></td>
<td><xsl:value-of select="element3" /></td>
<td><xsl:value-of select="element4" /></td>
</tr>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>

This will produce the table nicely, but what about the

<link>
<title>Title of the URL link</title>
<url>http://some.url.link</url>
</link>

structure I have in my XML file? I would like to be able to put such a
link structure inside any element I have in the XML record. The link
structure itself is easily enough translated into a URL with an XSL
transformation of

(XSL2)

<xsl:template match="//link">
<xsl:element name="a">
<xsl:attribute name="href">
<xsl:value-of select="url" />
</xsl:attribute>
<xsl:value-of select="title" />
</xsl:element>
</xsl:template>

But when I want to have the possibility of having URL links anywhere in
my HTML table, straight combining of (XSL1) and (XSL2) templates
fails...seems to have something to do with using the value-of structure
in (XSL1)...?

This ought to do it:

<xsl:template match="/">
<html>
<head>
<title>My HTML table</title>
</head>
<body>
<table border="1">
<head>
<tr>
<td><b>Element1</b></td>
<td><b>Element2</b></td>
<td><b>Element3</b></td>
<td><b>Element4</b></td>
</tr>
</head>
<xsl:for-each select="document/record">
<tr>
<xsl:for-each select="child::*">
<td><xsl:apply-templates select="link|text()" /></td>
</xsl:for-each>
</tr>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>

<xsl:template match="link">
<a href="{url}"><xsl:value-of select="title" /></a>
</xsl:template>

Thanks for the valuable tip. Everything seems to work just fine; I have
just one further question: for what is the "select="link|text()" needed?
Everything seems to work just fine for me even without that, so a plain

<xsl:for-each select="child::*">
<td><xsl:apply-templates /></td>
</xsl:for-each>

seems to be able to handle the links exactly correct...

It selects the <link /> element or a text node when available. I have put it
in mainly to show you how to work with apply-templates select attribute.

This can be very useful when you want to match specific nodes only...
