[xsl] make recursive call

["mary liu" <maryliu99@xxxxxxxxx>]

Hi,

I have a oldxml.xml file need to be converted to the newxml.xml file.  I can
only convert it to 2 levels and dont know how to make it recursive. I don't
know how deepth it is. My convert file is like this:

conver.xsl


<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="
http://www.w3.org/1999/XSL/Transform";>
<xsl:template match="/">

  <ResultSet>
    <xsl:apply-templates
select="ResultSet/data_service/Employeeprofile/row[@lev = 2]"/>
  </ResultSet>

</xsl:template>
<xsl:template match="row">
  <xsl:element name="branch">
  <xsl:attribute name="id">
              <xsl:value-of select="@emp_name" />
   </xsl:attribute>

    <branchText>
      <xsl:value-of select="@emp_name"/>
    </branchText>
     <xsl:call-template name="IterateRows">
      <xsl:with-param name="rows" select="following-sibling::node()"/>
    </xsl:call-template>
  </xsl:element>
</xsl:template>
<xsl:template name="IterateRows">
  <xsl:param name="rows"/>
  <xsl:if test="$rows[1]/@lev = 3">
    <leaf>
      <leafText>
        <xsl:value-of select="$rows[1]/@emp_name"/>
      </leafText>

    </leaf>
    <xsl:call-template name="IterateRows">
      <xsl:with-param name="rows" select="$rows[position()> 1]"/>
    </xsl:call-template>
  </xsl:if>
</xsl:template>
</xsl:stylesheet>




oldxml.xml

<ResultSet>
<data_service>
  <Employeeprofile>
<row emp_name="one" org_cd="73700" rpt_to_org_cd="11111"  lev="2" />
<row emp_name="four" org_cd="73656" rpt_to_org_cd="73700" lev="3"  />
<row emp_name="five" org_cd="75425" rpt_to_org_cd="73700" lev="3"  />
<row emp_name="three" org_cd="73723" rpt_to_org_cd="11111"  lev="2" />
<row emp_name="two" org_cd="73708" rpt_to_org_cd="11111"  lev="2" />
<row emp_name="Six" org_cd="73651" rpt_to_org_cd="73708" lev="3"  />
<row emp_name="Seven" org_cd="73632" rpt_to_org_cd="73651" lev="4"  />
<row emp_name="Eight" org_cd="73229" rpt_to_org_cd="73651" lev="4"  />
<row emp_name="nine" org_cd="74023" rpt_to_org_cd="73651" lev="4"  />
<row emp_name="ten" org_cd="73989" rpt_to_org_cd="11111"  lev="2" />
</Employeeprofile>
</data_service>
</ResultSet>

lev="2" is same level. Then lev=3, lev=4...
every level may have leaves or may not have leaves, like emp_name="two", it
has no leaf.

Attribute rpt_to_org_cd is the value pointing to the parent. for example
emp_name="Eight", rpt_to_org_cd ="73651", its parents' node is same as
emp_name="Seven" and emp_name="nine" which is emp_name="Six" org_cd="73651"

So the newxml.xml should be like this:


<ResultSet>
<branch id="one">
      <branchText>one</branchText>
      <leaf>
          <leafText>four</leafText>
      </leaf>
     <leaf>
        <leafText>five</leafText>
     </leaf>
  </branch>

  <branch id="three">
     <branchText>three</branchText>
  </branch>

  <branch id="two">
     <branchText>two</branchText>
      <branch id="Six">
     <branchText>Six</branchText>
     <leaf>
         <leafText>Seven</leafText>
     </leaf>
     <leaf>
           <leafText>Eight</leafText>
     </leaf>
         <leaf>
           <leafText>nine</leafText>
     </leaf>
  </branch>
   </branch>

   <branch id="ten">
     <branchText>ten</branchText>
  </branch>

</ResultSet>

Is there anybody helping me? Thanks in advance.
