How to Convert a Element to a different Element?

Question

I get a xml Element from others, for some reason
I must convert it to my format,
like add some attribute, change some attributes' name:
example, original include:
  <original id="000" name="father">
    <original id="001" name="first"/>
    <original id="002" name="second">
      <original id="003" name="third"/>
    </original>
  </original>after Change, it should be:
  <task id="000" abbr="father"> //change "original" to "task", change "name" to "abbr"
    <task id="001" abbr="first" day="" ok="no"/> // add a "ok" attribute
    <task id="002"> // remove a "name" attribute.
      <task id="003" abbr="third">
      <task id="004" abbr="fourth"> // insert a "task"
    </task>
  </task>  Would you give some example code.Thanks!

here is a style shet for your purpose
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="original[@name='father']">
<task id="{@id}" adrr="{@name}">
<xsl:apply-templates select="original[@name='first']"/>
<xsl:apply-templates select="original[@name='second']"/>
</task>
</xsl:template>
<xsl:template match="original[@name='first']">
<task id="{@id}" adrr="{@name}" day="" ok="no"/>
</xsl:template>
<xsl:template match="original[@name='second']">
<task id="{@id}">
<xsl:apply-templates select="original[@name='third']"/>
</task>
</xsl:template>
<xsl:template match="original[@name='third']">
<task id="{@id}" adrr="{@name}">
<task id="{concat('00',number(@id)+1)}" adrr="fourth"/>
</task>
</xsl:template>
</xsl:stylesheet>
