Static Variables For HTML Header

Parmy · February 20th, 2006, 02:09 PM

I'm relatively new to XSLT, at the moment I'm trying to create multiple outputs from a single XSLT file. All the output files contain more or less the same content in the HTML <head> element, except the <title> element.

Rather than repeating the HTML <head> each time it's required between the result-document elements, I have created a global variable called header:

<xsl:variable name"header">
  <head>
    <title>%%title%%</title>
  </head>
</xsl:variable>

Each time I require the header I simply use the:

<xsl:copy-of select="$header">

This works a treat.

The problem I'm having is trying to replace the "%%title%%" text, when I write the $header out.

For instance I have tried:

<xsl:copy-of select="substring-before($header, '%%title%%')"/>NEW TITLE<xsl:copy-of select="substring-after($header, '%%title%%')"/>

All I get back is "NEW TITLE".

Similarly if I try:
<xsl:copy-of select="replace($header, '%%title%%', 'NEW TITLE')"/>

If any one has any ideas on this, please help. Basically I want to be able to use a static global variable (which contains HTML elements) which contains a <title> element. When the global variable is written out, I want to be able to put a value of my choice between the <title> tags.

Thanks in advance.

Create a named template to output the header with a parameter

<xsl:template name"header">
  <xsl:param name="title"/>
  <head>
    <title><xsl:value-of select="$title"/></title>
  </head>
</xsl:template>

Then invoke it as

<xsl:call-template name="header">
  <xsl:with-param name="title" select="'Lord of the Rings'"/>
</xsl:call-template>
