xsl:if question

[djohnston]

I just need for a check on wether or not the node has any type of value numeric or alphabetic or alphanumeric. Doesn't really matter what value.

I tried something like this
<xsl:if "@asOF = true">
<value of selct = asOF>
</xsl:if>

With all the formatters im sure if you understand the question you understand what I mean. I just need a check for data so it knows to display it or not to.

Help appreciated alot.
Thanks.

try:

<xsl:if test="@asOF != "">
<xsl:value-of select="@asOF" /> 
</xsl:if>

Didn't work

It gives me a red underline and says required whitespace does not exist.

A little spelling error there, sorry about that, change the single double-quote in Xpath expression into double single-quotes. Yes, really You see, the test is to check if attribute asOF is not an empty string, and to use quotes within quoted expression you have at first level go from double-quote to single-quote as quotation marks. (At next level as usually done with composing Xml strings in Javscripts you have to escape the quotes with backslash \) Again:

<xsl:if test="@asOF != ''">
<xsl:value-of select="@asOF" /> 
</xsl:if>

Thanks alot

Its not a database value so i just omitted the @
But other then that thanks alot The report will look alot more professional now that i can ommit fields.

Well I'm thinking about maybe making some forums of my own,
its probably a really good way to learn.

If not maybe i can get admin to one of these forms i post on once i get good enough.

I mean i know starting i can just use msdn to answer questions but im only looking at about my 3rd week of programming.

Its not a database value so i just omitted the @

FYI, in XPath the @ signifies an attribute of a Xml node.

Ok thats cool

Ohh lol ya I'm actually just displaying it with a gui interface.

So I'm not really using xpath.

I think lol.

FYI: Only on my third week of programming lol.

 

[JohnH]

funny, the expression in the 'test' attribute of xsl:if element is an XPath expression. So when you're doing asOF != '' you're doing XPath. There are good Xml, Xsl(t), Xpath tutorials at the W3 Schools http://www.w3schools.com/

Ya i was just playing around.
I am still a programming newbie but I will continue to get better at it.

Im thinking about this weeked and I am probably going to create a tetris like game then move up from there.

Thanks for the help.
