Problem with Parameter binding with String

Hi,


I am trying again here. Hope someone can help me on
this.

I have a test.xml and a name list in another xml file
called lookup.xml. I open the test.xml and also look
at the lookup.xml to see if there is any element
missing in the test.xml. If exists, I can just copy
the element into the result tree; if not, i can create
that one.

A template can do this job like:


<xsl:call-template name="replacement">
<xsl:with-param name="pName" select="'XX'"/>
<xsl:with-param name="defaultValue" select="'+'"/>
</xsl:call-template>



<xsl:template name="replacement">
        <xsl:param name="pName"/>
        <xsl:param name="defaultValue"/>        
        <xsl:choose>
          <xsl:when test="*[name(.) = $pName]">         
<xsl:copy-of select="?????"/>
          </xsl:when>
          <xsl:otherwise>
                <xsl:element name="{$pName}">
                <xsl:value-of select="$defaultValue"/>
                </xsl:element>
          </xsl:otherwise>
        </xsl:choose>
</xsl:template>

test.xml:

<Member>
  <XX>1</XX>
</Member>


I have to call the template replacement and pass the
pName as string since that is the thing I got from
lookup.xml. But in the template I just can NOT copy
that XX element and value because the pName is a
string. Is this the same problem like converting a
string into node-set? Or is there any workaround for
this.


Thanks


Dongling
