[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Re: dynamic pages with URL parameters
 Ben,
Yes. The parameters passed on the url to a servlet are automatically
inserted into the XML tree result. So they can then be accessed via the XSL.
This has the same effect as creating a CGI query object in Perl or passing
params on the URL to a PHP. The code below shows storing a value from the
URL, which is represented in the "param" node of the XML, into an XSL
variable which is then used later in the page:
<xsl:variable name="max_per_page">5</xsl:variable>
<xsl:variable name="start"><xsl:value-of
select="/root/params/start"/></xsl:variable>
<xsl:variable name="end"><xsl:value-of select="number($start) +
number($max_per_page) - 1"/></xsl:variable>
Then, this code shows two ways to grab values from the URL and put them into
another URL - one using javascript (the uncommented) and one using an
attribute tag to modify a src attribute (commented code):
<?xml version='1.0'?>
<xsl:stylesheet version='1.0'
xmlns:xsl='http://www.w3.org/1999/XSL/Transform'>
<xsl:template match="/">
<HTML>
<HEAD><TITLE>Zatso Enhancements</TITLE>

</HEAD>
<xsl:call-template name="EnhancementFrameset">
<xsl:with-param name="storyID">
<xsl:value-of select="/root/session/url/storyID" />
</xsl:with-param>
<xsl:with-param name="enhancementIndex">
<xsl:value-of select="/root/session/url/enhancementIndex"
/>
</xsl:with-param>
</xsl:call-template>
</HTML>
</xsl:template>
<xsl:template name="EnhancementFrameset">
<xsl:param name="storyID">0</xsl:param>
<xsl:param name="enhancementIndex">0</xsl:param>

function loadFrames()
{
document.frames[0].location = unescape(menuURL);
alert('going to load: '+ menuURL)
document.frames[1].location = unescape(displayURL);
}
