Re: Limiting the number of RSS-items shown in result t

XSLT 1.0 does not allow you to use <xsl:sort/> on dates.
EXSLT has some support for comparing dates, noteably date:difference.
If your pubDate was in the DateTime format defined in XSL Schema
datatypes (http://www.w3.org/TR/xmlschema-2/#dateTime), you could use
date:format-date (also EXSLT) to genereate a numerical representation
you can use <xsl:sort/> on.

Perhaps something like this:
<xsl:for-each select='/item[position() &lt; 11 and not(category='A')]'>
	<xsl:sort select='date:format-date(pubDate,"ssmmHHDD")'/>
	<xsl:if test='position() < 4>
		<!-- include -->
	</xsl:if>
</xsl:for-each>

I also noticed that in your example, the rss feed is already sorted
descending by date, can you rely on that? If so, you could use
position() again to get the latest elements.

| I manage two web sites on which I want to visualize a shared RSS 2.0
feed, but only partly. The items shown depend on the contents of the RSS
feed's <category> tag and I only want to show the three most recent
items selected. The RSS feed contains items categorized as either 'A',
'B' or 'both'.
|
| On web site 1, I want to show exactly 3 items from categories 'A' and
'both' (hence: not B), on site 2 I want to show exactly 3 items from
categories 'B' and 'both' (hence: not A)
|
| It's no problem to limit the number of input items, for example, to 10:
| <xsl:if test="position() < 11">
|
| and select them:
| <xsl:if test="not(category='A')">
|
| My question: how can I limit the result tree to the 3 most recent,
selected items out of a total of 10 items?
|
| Parsing is done with classic asp. All files are on the same server.
|
| The RSS sample feed can be found at
http://users.pandora.be/chunga/RSSsamplefeed.xml
|
| The xsl files : see http://users.pandora.be/chunga/RSSsamplefeed_notA.xsl
| http://users.pandora.be/chunga/RSSsamplefeed_notB.xsl
|
| Hope someone can help.
