please consider the below code..

<xsl:if test="$HD='OH'">
    <xsl:variable name="variable1" select="ABC" />
</xsl:if>

How to access the value of "variable1"(which is inside the if block)out side the if block.or please give me the alternative solution for the above

You can't do that because once outside of the <xsl:if> the variable is no longer in scope.

You can place the <xsl:if> inside the variable however:

<xsl:variable name="variable1">
  <xsl:if test="$HD='OH'>ABC</xsl:if>
</xsl:variable>

or in XSLT 2.0 inline:

<xsl:variable name="variable1" select="if ($HD='OH') then 'ABC' else ''"/>

Hi Sam,

But here my case is different

am getting the CSV file in that first record is always Header and the remaining are the actual records

i would like to generate a XML file by taking the actual record value's but in while generating the xml i need to generate the few tag's by taking the data from the header also

so that's the reason why i want to store header information in global varible so that i can use when ever required


Please find the my XSLT

You're still thinking very procedurally; you need to learn to think in a more declarative, functional style. You really don't want to use calls to Java methods such as nextToken() that depend on the order of execution. In fact this kind of thing is a lot easier in XSLT 2.0 where you don't need calls to extension functions at all.

The XSLT way to do this is something like this:

<xsl:variable name="tokens" select="str:tokenize(...)"/>
<xsl:variable name="h1" select="$tokens[1]"/>
<xsl:variable name="h2" select="$tokens[2]"/>

etc.

Hi Kay...m not using XSLT 2.0 version...can u plz help me for XSLT ver 1.0

Hi Michael,

Thanks for the solution,

But here the problem is am using the Adapter developed by my client that will support Xalan Parser(xalan parser supports only XSLT1.0)

So i can't go for the XSLT2.0, Please give any solution by using XSLT1.0

is it possible to do with the exslt name space?

Michael's code example above is XSLT 1.0.

If you are already using the str:tokenize function then there is little point in doing the same thing but calling out to java, as its not needed.

It's crashing in Xalan, presumably when calling the extension function. You will have to go to the Xalan support forum for this, or use a different product.

Really there is not much point in using XSLT 1.0 with vendor extensions when you could write this so easily in XSLT 2.0.

You didn't follow Sam's suggestions anyway. There's no point coming here for help if you won't take our advice.

My suggestion was to not use the Java Tokenizer at all, yet you are still trying to use it.

You are then trying to access the Tokenizer like it is an array, which given the fact you where accessing it correctly in the first post you should know better.
