Re: [xsl] sort by xsl:if and then sort using templates?

---

---

I'm also learning XSLT and XPath, it definitely needs to be understood from
scratch even though I have background knowledge of several other programming
languages. 
XSLT and XPath are quite different but very interesting.

I
started with these tutorials here, they give a good foundation, but they're
terse.

http://www.w3schools.com/xpath/
Practicing on smaller and simpler examples on your own also helps in
discovering and understanding it. I'm now reading few books on XSLT2.0 to
understand it properly.

But if you have any questions big or small don't
hesitate to ask here, if they are not already answered.

Thank you
for the guidance Rashmi and David,

I seem to not be able to wrap my head
around how the XSLT processor
works, I will be doing some reading and then
getting back at this
problem.

Thanks again,

Max Bronsema

Which version of XSLT/XPATH? I dont
think you can compare dates with >
in XPATH1.0

You can't nest xsl:sort inside
xsl:if.
xsl:if can only be nested under <xsl:apply-templates> and
<xsl:for-each>

I think if you represent dates in the standard format for
example:
2005-05-07T19:30:00  instead of 05/07/2005 you can simply sort dates
without having to extract the substrings of year, month and day with
reference
to the code snippet you have provided.

like this:
<xsl:apply-templates>
<xsl:sort select="date"/>
</xsl:apply-templates>
