Hi
I would like to move tags beginning with a certain string (and their contents) out from one level to the upper

In the example below (that should help you in understand my request), I would like to move all tags beginning by FR_Sched_ from START/MAIN/Sched_* level to START/MAIN level
Please find an example of what I have and the result expected:
--------------------------------------------------------------------------------------------------------------
Original XML:
<START>
        <HEADER>
                <DATA1>1</DATA1>
                <DATA2>2</DATA2>
        </HEADER>
        <MAIN>
                <Bonds>
                        <SD>2006-01-18</SD>
                        <MaturityDate>2007-07-18</MaturityDate>
                        <Principal>110</Principal>
                </Bonds>
                <Sched_0>
                        <FR_Sched_0>
                               <FR_ShortName>ShortName1</FR_ShortName>
                        </FR_Sched_0>
                        <Outsanding>200</Outsanding>
                        <StartDate>2006-01-18</StartDate>
                        <EndDate>2006-07-18</EndDate>
                </Sched_0>
                <Sched_1>
                <Outsanding>400</Outsanding>
                        <StartDate>2006-07-18</StartDate>
                        <EndDate>2007-01-18</EndDate>
                </Sched_1>
                <Sched_2>
                        <FR_Sched_2>
                               <FR_ShortName>ShortName2</FR_ShortName>
                        </FR_Sched_2>
                        <Outsanding>1000</Outsanding>
                        <StartDate>2007-01-18</StartDate>
                        <EndDate>2007-07-18</EndDate>
                </Sched_2>
        </MAIN>
</START>
--------------------------------------------------------------------------------------------------------------

Expected XML:

        </MAIN>
</START>

Is it feasible?

Feel free to ask me if you need more info.

Best Regards.
Stefan.

Usual approach to this kind of problem is to define an identity template as your default template:

<xsl;template match="*">
 <xsl:copy><xsl:copy-of select="@*"/><xsl:apply-templates/></xsl:copy>
</xsl:template>

and the add template rules for elements that need changing.

You need to change the MAIN element

<xsl:template match="MAIN">
<xsl:copy>
  <xsl:apply-templates/>
  <xsl:copy-of select="*/*[starts-with(name(), 'FR_Sched')]"/>
</xsl:copy>
</xsl:template>

and the template for FR_SCHED elements:

<xsl:template match="*[starts-with(name(), 'FR_Sched')]"/>

Incidentally, <FR_SCHED no="n"> is much better XML design than <FR_SCHED_n>.
