Re: [xsl] variable never matched hardcoded string

Hello Maizatul,

you have some strange things in your code - maybe these are only typos 
in the mail.

In this template you declared twice the variable "ABC", what's an error.

Furthermore you are creating Result Tree Fragments in your parameters, 
where you want to have a string. That's not really bad, but can be 
avoided by writing <xsl:with-param name="xyz" select="'action'"/>.

For information on RTF see

Should this template be named 'xyz'??

What template do you apply on these nodes?

right parenthesis?                                   ^^^

>           <xsl:if test = "consist(@fid,'039')">
There is no function consist(), I assume you mean contains().

Why not simply

<xsl:template match="message">
  <xsl:variable name="ABC" select="dataContent/dataValue[contains(@fid, 
'039')"/>
  <xsl:variable name="DEF" select="dataContent/dataValue[contains(@fid, 
'055')"/>
  ...
</xsl:template>

Or if you really want to collect all cases in an extra template:

<xsl:template match="message">
  <xsl:variable name="ABC">
    <xsl:apply-templates select="dataContent/dataValue">
      <xsl:with-param name="p_Code" select="'stock'"/>
    </xsl:apply-templates>
  </xsl:variable>
  <xsl:variable name="DEF">
    <xsl:apply-templates select="dataContent/dataValue">
      <xsl:with-param name="p_Code" select="'action'"/>
    </xsl:apply-templates>
  </xsl:variable>
</xsl:template>

<xsl:template match="dataContent/dataValue">
  <xsl:param name="p_Code" select="''"/>
  <xsl:choose>
    <xsl:when test="$p_code = 'stock' and contains(@fid, '039')">
      <xsl:value-of select="."/>
    </xsl:when>
    <xsl:when test="$p_code = 'action' and contains(@fid, '055')">
      <xsl:value-of select="."/>
    </xsl:when>
  </xsl:choose>
</xsl:template>

But I don't see really sense in the second way, maybe you have to 
explain your problem a bit more.

Hope this helps,

Joerg
