Re: Applying template with a variable

Hi,

Is it possible in apply of template do variable selection in XSLT 1.0?

1. The variable authobj consists of authentication-object node.
2. <xsl:apply-templates select="$authobj"/> should launch the <xsl:template

Note: The template with match //authentication/object is in different

<xsl:variable name="locauthobjs"

<xsl:variable name="globauthobjs"

select="document('../etc/policyglobal.xml')/config/authentication-objects/aut
hentication-object"/>

<xsl:template match="//authentication/object">
   <xsl:variable name="authobj">
      <xsl:call-template name="authobjbyname">
         <xsl:with-param name="name" select="."/>
      </xsl:call-template>
   </xsl:variable>
   <xsl:apply-templates select="$authobj"/><!-- [1.] -->
</xsl:template>

<xsl:template match="authentication-object[type = 'plain-file']"><!-- [2.]

   <xsl:variable name="keyfiles">
      <xsl:call-template name="key_file">
         <xsl:with-param name="path" select="path"/>
      </xsl:call-template>
   </xsl:variable>
   <exteranal-key type="{'software'}" init-info="{$keyfiles}"/>
</xsl:template>

<xsl:template name="authobjbyname">
   <xsl:param name="name"/>
      <xsl:if test="$name !=''">
         <xsl:choose>
            <!-- Test if it exists in the local file? -->
            <xsl:when test="$locauthobjs[@name=$name] !=''">
               <xsl:value-of select="$locauthobjs[@name=$name]"/>
            </xsl:when>
            <xsl:otherwise>
               <!-- It seems to exist in the global file!-->
               <xsl:value-of select="$globauthobjs[@name=$name]"/>
            </xsl:otherwise>
         </xsl:choose>
      </xsl:if>
</xsl:template>

<xsl:template name="key_file">
   <xsl:param name="path"/>
   <xsl:variable name="totlen">
      <xsl:value-of select="string-length($path)"/>
   </xsl:variable>
   <xsl:if test="$totlen > 0">
      <xsl:variable name="cert_pos">
         <xsl:value-of select="$totlen -

      </xsl:variable>
      <xsl:variable name="cert_len">
         <xsl:value-of select="string-length(substring-before($path, ' ')) +

      </xsl:variable>
      <xsl:value-of select="'key_file('"/>
      <xsl:value-of select="substring($path, $cert_pos, $cert_len)"/>
      <xsl:value-of select="','"/>
      <xsl:value-of select="substring($path, $totlen -

      <xsl:value-of select="')'"/>
   </xsl:if>
</xsl:template>

Here below is a snippet from the input file. There can also exists

authentication-object:s in policyglobal.xml file, thats why <xsl:template
name="authobjbyname"> is needed.

<config>
 <authentication-objects>
  <authentication-object name="My_test_665_private_key">
    <type>plain-file</type>
    <path>cert//C:/Temp/Certs/cert1.bin

  </authentication-object>
  <authentication-object name="MyTestProfileSecret">
    <type>pre-shared-key</type>
    <path>hoobar</path>
  </authentication-object>
  <authentication-object name="NewTestKey">
    <type>pre-shared-key</type>
    <path>funny_hey</path>
  </authentication-object>
 </authentication-objects>
 <policy-rules>
  <ipsec-rules>
    <rule name="CertificateAuthentication">
       <authentication>
         <object>
           My_test_665_private_key
         </object>
       </authentication>
    </rule>
    <!-- There exists several rules here! -->
  </ipsec-rules>
 </policy-rules>
</config>

Desired output:
<!-- Those authentication-objects with type = 'plain-file' which are used in

<exteranal-key type="software"

Hopefully you get the point.

I changed my XSLT code to:
  <xsl:template match="//authentication/object">
     <xsl:variable name="name" select="."/>
     <xsl:choose>
        <xsl:when test="$locauthobjs[@name=$name] !=''">
           <xsl:apply-templates select="$locauthobjs[@name=$name]"/>
        </xsl:when>
        <xsl:otherwise>
           <xsl:apply-templates select="$globauthobjs[@name=$name]"/>
        </xsl:otherwise>
     </xsl:choose>
  </xsl:template>

so <xsl:call-template name="authobjbyname"> wasn't needed anymore. This seems
to work. For me it seems that in XSLT 1.0 variables can't contain node-sets!
