storing value in variable

Hari7 · November 10th, 2009, 11:01 AM

Hi,

I want to declare a variable with file name and path and use that variable in the code. But it is returning the data in variable instead of string which i am assign to variable.

code is below :

Code:

<xsl:variable name="path">

<xsl:value-of select="document('enhanced-newssheets.xml')/./*[@Id=$topic]"></xsl:value-of>
 </xsl:variable>

How can i get the exact string as value in variable ?

Thanks for your help

Hari

'data in variable' and 'string I am assigning to variable' mean the same thing to me.

<xsl:value-of select="$path"/> will output whatever is in the variable.

What i mean is i want the below string in the variable.

'document('enhanced-newssheets.xml')/./*[@Id=$topic]'

but instead its returning data from the xml document.

I can't see why you would, but just do the following:

<xsl:variable name="path">document('enhanced-newssheets.xml')/./*[@Id=$topic]</xsl:value-of>

Standard XSLT doesn't allow you to construct XPath expressions as strings and then evaluate them dynamically.

Many products have an extension that does this: look for saxon:evaluate(), xalan:evaluate(), dyn:evaluate() or similar functions.
