Re: questions.

I am trying to write a diff-patch tool for xml data in which i will be doing
the patching using xslt. I have some questions regarding this.

consider the two xml files as

        a                               a
            |                                   /   |    \
            b                                        m    b      n
            |                                      /        |
        c                                    z         c

The edit script that i will be generating will be

1. Add subtree at m as first child of a
2. Add node n as the third child of n

How i can i achieve this in xslt ?  (I know that xslt will generate a
completely new file. )

1. Copy a.  Within a:
2. Create m.
3. Copy the first child of a.
4. Create n.
5. Copy the 2nd and following children of a.

<xsl:template match="a">
  <xsl:copy>
    <xsl:copy-of select="@*"/>
    <m/>
    <xsl:apply-templates select="*[1]"/>
    <n/>
    <xsl:apply-templates select="*[position() &gt;= 2]"/>
  </xsl:copy>
</xsl:template>

HTH,
Chris
