Hallo again,

I have used a choose while check for my date type and now what I want to do is to check if the month has a valid value for example February cannot be 31 days. So it is something like that

mm = month variable
dd = day variable
<xsl:choose>
<xsl:when test ="number($mm)=1 or number($mm)=3 or number($mm)=5 or number($mm)=7 or number($mm)=8 or number($mm)=10 or number($mm)=12">
<xsl:if test ="number($dd)>31 or number($dd)<1">
<xsl:text>Invalid day value</xsl:text>
</xsl:if>
</xsl:when>
</xsl:choose>

I have another question. with mm variable I have many or connectives. Is there any other practical solution for it? It is quite long to write such a statement.

You can cut the length a lot by putting number($mm) in a variable.

In XSLT 2.0 you can do $x=(1,3,5,7,8,10,12). But in 2.0 you've got date/time functions so you wouldn't need this logic anyway.

1.0 just tends to be verbose: live with it, or move to 2.0

Michael unfortunately I am no longer a Java Developer I am developing C# under VS 2005 with .NET2.0 That means I have to use XSLT 1.0

So my another question has not been yet answered. Can I use xsl:if in xsl:while in XSLT 1.0 like the example above?

No, it doesn't: try Saxon for .NET.

There's no such instruction as xsl:while. If you mean can you use xsl:if within xsl:when, then yes, of course you can.
