I've a project where the XML should be transformed.

If a tag exists in Output and Parameters, the Parameters one should be
replaced by the Output corresponding and its childs.

Example: (XML In):

<RESULT>
<PARAMETERS>
<CYCLE>
<ENDDATE></ENDDATE>
<NUMBER>50</NUMBER>
</CYCLE>
<FILE>
<CHECK>Yes</CHECK>
</FILE>
<DIR>
<NAME>ONE</NAME>
</DIR>
<RUNTYPE>SAMPLE</RUNTYPE>
</PARAMETERS>
<OUTPUT jobfactor="71">
<CYCLE>
<NAME>MARY<\NAME>
<SURNAME>ROSE<\SURNAME>
</CYCLE>
<FILE>
<FILENAME>E:\ftphome\vodafone\xml\CC20060215S50.XM L</FILENAME>
</FILE>
</OUTPUT>
</RESULT>

(XML Out):

<PARAMETERS>
<CYCLE>
<NAME>MARY<\NAME>
<SURNAME>ROSE<\SURNAME>
</CYCLE>
<FILE>
<FILENAME>E:\ftphome\vodafone\xml\CC20060215S50.XM L</FILENAME>
</FILE>
<DIR>
<NAME>ONE</NAME>
</DIR>
<RUNTYPE>SAMPLE</RUNTYPE>
</PARAMETERS>

I've done somtehing like this:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0"
encoding="iso-8859-1"></xsl:output>
<xsl:template match="*">
<xsl:copy>
<xsl:apply-templates />
</xsl:copy>
</xsl:template>
<xsl:template match="OUTPUT"></xsl:template>
<xsl:template match="/RESULT/PARAMETERS/FILE">
<xsl:copy-of select="/RESULT/OUTPUT/FILE" />
</xsl:template>
</xsl:stylesheet>

but this only works if FILE exists, it is not generic. Might you help
me, please?

Its urgent.

It's impossible to answer this because you haven't defined what
"corresponds" means, Usually a problem like this has an id attribute
somewhere and it's a question of writing predicates that either match,
or exclude elements with matching ids.

In your example, is "correspondence" just based on position? Can there
be more than one "Output" or "Parameter" in the document ?

Tell us what "corresponds" means, and we can probably help you.

Thank you in advance.

If and only if a tag from Parameters, exists in Output (with the same
name). This tag in Output should overwrite the tag with the same name
in Parameters.

<Parameters>
<A>
<B>One<B/>
<A/>
<D>
<E>Three<E/>
<D/>
<Parameters/>
<Output>
<A>
<C>Two<C/>
<A>
<Output/>

the XSLT should transforms it into:

<Parameters>
<A>
<C>Two<C/>
<A/>
<D>
<E>Three<E/>
<D/>
<Parameters/>

The A tag (and its childs) were copied from Output into Parameters.

That isn't XML. Your end-tags are all defective.

Assuming you fix up your file, try this.

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">

<xsl:output method="xml"/>

<xsl:template match="Parameters">
<Parameters>
<xsl:apply-templates/>
</Parameters>
</xsl:template>

<xsl:template match="Parameters/*">
<xsl:choose>
<xsl:when test="../../Output/*[name()=current()/name()]">
<xsl:copy-of select="../../Output/*[name()=current()/name()]"/>
</xsl:when>
<xsl:otherwise>
<xsl:copy-of select="."/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>

</xsl:stylesheet>
