I have the following structure...
<value>
<item priority ="2"> First </item>
<item priority ="1"> Second </item>
<item priority ="1"> Third </item>
<item priority ="3"> Fourth </item>
<item > Fifth </item>
<item > Sixth </item>
</value>

Is it possible for me to do sorting using xsl:sort where 'item' with priority ="1" should come first and those with priority ="2", then those item which does not have a priority attribute and then item with priority >=3 (3,4,5,6.....).


If u have any other way of sorting, plzz lemme know.

TIA,
debo

You're splitting it up kinda like so I guess:
Inside the value template:
<xsl:apply-templates select="item[@priority=1]"/>
<xsl:apply-templates select="item[@priority=2]"/>
<xsl:apply-templates select="item[not(@priority)]"/>
<xsl:apply-templates select="item[@priority &gt;=3]"/>

is this what you're looking for?

In XSLT 2.0

xsl:sort select="number((@priority, 2.5)[1])"

In 1.0 conditional expressions are more difficult, but you can use the substring() trick:

substring("2", 1, boolean(@priority)) is "2" if @priority exists, "" otherwise, so your sort key is

select="concat(@priority, substring('2.5', 1, boolean(@priority)*3))"
data-type="number"
