Re: Node set

Hi YueMa,

As David "pure mathematician" Carlisle says, node sets aren't ordered,
so you can't create one with an order, but you can choose what order
to process them in.

> How about if I want to  display like:
> title2
> title4
> title1
> title3

Then apply templates (or use xsl:for-each) in that order:

  <xsl:apply-templates select="title2" />
  <xsl:apply-templates select="title4" />
  <xsl:apply-templates select="title1" />
  <xsl:apply-templates select="title3" />

This hardcodes into the stylesheet the order in which they're
processed in a certain context.  You could select the order in any
number of ways.

There must be some underlying way of choosing which order you want
them in?  What is it?

Not really (although you could feasibly create a result tree fragment
variable and then iterate over that with xsl:for-each having turned it
into a node set with an extension function).

If you apply templates to the nodes you want in order, as outlined
above, then you can have a template that matches any of them and that
contains whatever you want to put in the body of the xsl:for-each:

<xsl:template match="title1 | title2 | title3 | title4">
   ... body of the xsl:for-each ...
</xsl:template>

I hope that helps,
