Re: Tag Replacement

It's much easier to do this with templates than to use for-each:

<xsl:template match="/">
  <vxml version="1.0" application="your-app-root.vxml">
    <xsl:apply-templates/>
  </vxml>
</xsl:template>

<xsl:template match="card">
  <form id="{@id}">
    <field name="youNeedToHaveANameForYourFieldsToBeValidVXML"> <!-- :) -->
      <prompt>
        <xsl:apply-templates/>
      </prompt>
    </field>
  </form>
</xsl:template>

<xsl:template match="a">
  <!-- special handling for anchors.  Unless you explicitely define a 
template for something, it's text will be output (so the text in the <p> and 
<strong> will still be output, even though there is no template matching "p" 
and "strong") -->
  <voice gender="female">
    <xsl:apply-templates/>
  </voice>
</xsl:template>


Using xsl:apply-templates does basically the same thing as your for-each, but 
it allows you to specify a different template for each node.  The default 
template, which is used if you don't have one that matches a node, is similar 
to what you have already, which is basically to do <value-of select="."/>.  
Each time xsl:apply-templates is used, it basically does a for-each on each 
of the child nodes of the current node, and for each node it finds a template 
that matches that node and outputs the contents of the template.

If you still want to use xsl:for-each (though I don't recommend it in almost 
all cases; templates are much simpler once you get the hang of them), you 
could replace your inner for-each with:

<xsl:for-each select="*">
  <xsl:choose>
    <xsl:when test="self::a">
      <voice gender="female">
        <xsl:value-of select="."/>
      </voice>
    </xsl:when>
    <xsl:otherwise>
      <xsl:value-of select="."/>
    </xsl:otherwise>
  </xsl:choose>
</xsl:for-each>

Once you get the hang of templates, though, you won't want to go back except 
in relatively rare cases.
