RE: several questions on XML to HTML processing with XSL

["Albert, Kevin" <kjalbert@xxxxxxxxxxxxxxxxxxxxx>]

I thought it would be nice to do something like this, but I couldn't get it to work (does anybody know if a construct like this is possible):
<xsl:variable name="ParamName">param2</xsl:variable>
<xsl:template match="blah_blah">
  <xsl:call-template name="SomeTemplateName">
    <xsl:with-param>
      <xsl:attribute name="name">
        <xsl:value-of select="$ParamName"/>
      </xsl:attribute>
    </xsl:with-param>
  </xsl:call-template>
</xsl:template>

Anyway, maybe this is not the best solution but it will do what you want:

  <xsl:variable name="ParamName">param2</xsl:variable>

  <xsl:template match="blah_blah">
    <xsl:if test="$ParamName='param1'">
      <xsl:call-template name="SomeTemplateName">
        <xsl:with-param name="param1">false</xsl:with-param>
      </xsl:call-template>
    </xsl:if>
    <xsl:if test="$ParamName='param2'">
      <xsl:call-template name="SomeTemplateName">
        <xsl:with-param name="param2">false</xsl:with-param>
      </xsl:call-template>
    </xsl:if>
    <xsl:if test="$ParamName='param3'">
      <xsl:call-template name="SomeTemplateName">
        <xsl:with-param name="param3">false</xsl:with-param>
      </xsl:call-template>
    </xsl:if>
    <xsl:if test="$ParamName='param4'">
      <xsl:call-template name="SomeTemplateName">
        <xsl:with-param name="param4">false</xsl:with-param>
      </xsl:call-template>
    </xsl:if>
  </xsl:template>

Sorry, I left something out. The template 'SomeTemplateName' has several
parameters which I initialised to
a default value and I only want to set one to a different value, but this
one parameter can be variable.

So it's something like this:

<xsl:template name="SomeTemplateName">
<xsl:param name="param1">true</xsl:param> 
<xsl:param name="param2">true</xsl:param>
<xsl:param name="param3">true</xsl:param>
<xsl:param name="param4">true</xsl:param>

<!-- do some processing here based on the value of the parameters -->

</xsl:template>

the variable "ParamName" will be either "param1", "param2" etc. and
'whateverValue' could be e.g. 'false'.

So instead of passing on the value of all parameters I just want to pass on
the only parameter that's changed.

I vaguely recall that someone has once asked a similar question, but I can't
find it in the archives.
