dishant · October 26th, 2007, 07:12 AM

Hey I m trying to Access a Variable from template i m not Abel to do it , please can any one tell me how to do that

i doing in this way :

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:variable name="Append">
        <xsl:value-of select="'~'"/>
    </xsl:variable>
    <xsl:variable name="Status">
        <xsl:value-of select="0"/>
    </xsl:variable>
    <xsl:element name="INFORMATION">
        <xsl:choose>
            <xsl:when test="DATA[MessageName='Verify']">
                <xsl:call-template name="Inquiry">
                </xsl:call-template>
            </xsl:when>
            <xsl:when test="DATA[MessageName='Verify1']">
                <xsl:call-template name="Inquiry1">
                </xsl:call-template>
            </xsl:when>
        </xsl:choose>
    </xsl:element>
    <xsl:template name="Inquiry">
        <xsl:value-of select="$Append"/>
        <xsl:value-of select="$Status"/>
    </xsl:template>
    <xsl:template name="Inquiry1">
        <xsl:value-of select="$Append"/>
        <xsl:value-of select="$Status"/>
    </xsl:template>

    <xsl:template match="text()"/>
</xsl:stylesheet>

The variables look fine, but the <xsl:element> isn't a top level declaration, so should be inside something else, like a <xsl:template> declaration.

Don't do this:

<xsl:variable name="Append">
<xsl:value-of select="'~'"/>
</xsl:variable>

do this instead:

<xsl:variable name="Append" select="'~'"/>

It's one line of code instead of 3, and it's much more efficient because the variable is a simple string rather than an XML document.

XSLT variables have static scope, like variables in C or Java - you can't access them outside the template where they were declared. If you want to pass them to another template, you need parameters - look up xsl:with-param and xsl:param, any XSLT book will give you examples of their use.

>but the <xsl:element> isn't a top level declaration

Sorry, I missed that. Because the variables were on the same level as xsl:element, I assumed they were local variables within a template.

Thanx Michael Kay

But My Problem is that i want all the Data in one sting separated by " ~ " .

so thats why i m taking node one by one without <xsl:element> because if i use <xsl:element> then i will get value in numbers of node but i want them in one node

so can u give me sum examples how to do that

You ARE using <xsl:element> but you shouldn't be, at least not there. I suspect it should read: <xsl:template match="INFORMATION"> etc.

Even if the above was a correct XSLT stylesheet it wouldn't output anything apart from a '~' and the number 0.

You probably want to do something with <xsl:for-each> but its hard to say what without seeing a sample of your input XML (a small sample will do) and what you want the output to look like.

Just off the top of the head think along these lines...

Code:

<xsl:for-each select="DATA">
  <xsl:value-of select="string(.)"/>
  <xsl:if test="position != last()">
    <xsl:value-of select="'~'"/>
  </xsl:if>
<xsl:for-each>

Hi samjudson,

right now i m not giving any input i m just trying it with harcoded value but problem is that when i m trying this

<xsl:template name="Inquiry">
   <xsl:value-of select="$Append"/>
   <xsl:value-of select="$Status"/>
   <xsl:value-of select="$Append"/>
   <xsl:value-of select="$Status"/>
</xsl:template>

and right now i m not taking any value form XML thats y i m not using <xsl:template match="INFORMATION">
I am only getting value for Append [ie ~ ] but i want value in string i.e [ ~0~0 ] and i m not getting that . so could u plz tell me what is the way to get that

and if i do about exampel in other vay way i.e

<xsl:template name="Inquiry">
    <xsl:element name="Append">
       <xsl:value-of select="$Append"/>
    </xsl:element>
    <xsl:element name="ProcessingStatus">
       <xsl:value-of select="$Status"/>
    </xsl:element>
</xsl:template>

it is woring but i want that in string not in node

Please don't use text shorthand. It takes twice as long to read, and I'm a busy person.

I think it would help if you explain exactly (and completely) what your source document and stylesheet look like, what output you are getting, and what output you want.
