Xsl for removing specific nodes and modifying one node.

Question

Hello,
i have the urgent need to remove specific nodes
and modify one node in my XML.
the xml as input :
<?xml version="1.0" encoding="utf-8"?>
<PLOT>
  <REQUEST>
    <GET_LAYOUT>
      <PROPERTIES>
        <MAPNAME name="xxxx" />
       </PROPERTIES>
      <DATAFRAME id="MAIN">
        <LAYERLIST>
          <LAYERDEF id="0" visible="false" query="" />
          <LAYERDEF id="1" visible="false" query="" />
          <LAYERDEF id="2" visible="false" query="" />
          <LAYERDEF id="3" visible="false" query="" />
          <LAYERDEF id="4" visible="false" query="" />
          <LAYERDEF id="5" visible="false" query="" />
          <LAYERDEF id="6" visible="false" query="" />
          <LAYERDEF id="7" visible="false" query="" />
          <LAYERDEF id="8" visible="false" query="" />
          <LAYERDEF id="9" visible="false" query="" />
          <LAYERDEF id="10" visible="false" query="" />     
        </LAYERLIST>
        <MAPSERVICELIST>   
          <MAPSERVICEDEF  service="BASEMAP" >
            <LAYERLIST>
              <LAYERDEF id="2" visible="True" query="" />
              <LAYERDEF id="1" visible="False" query="" />
            </LAYERLIST>
          </MAPSERVICEDEF>
          <MAPSERVICEDEF service="MAP1">
            <LAYERLIST>
              <LAYERDEF id="4" visible="True" query="" />
              <LAYERDEF id="3" visible="True" query="" />
              <LAYERDEF id="2" visible="True" query="" />
              <LAYERDEF id="1" visible="False" query="" />
            </LAYERLIST>
          </MAPSERVICEDEF>
        </MAPSERVICELIST>
      </DATAFRAME>
    </GET_LAYOUT>
  </REQUEST>
</PLOT>
what i want to have is:
<?xml version="1.0" encoding="utf-8"?>
<PLOT>
  <REQUEST>
    <GET_LAYOUT>
      <PROPERTIES>
        <MAPNAME name="xxxx" />
      </PROPERTIES>
      <DATAFRAME id="MAIN">
        <LAYERLIST>
   <LAYERDEF id="6" visible="True" query="" />
            <LAYERDEF id="5" visible="True" query="" />
            <LAYERDEF id="4" visible="True" query="" />
            <LAYERDEF id="3" visible="False" query="" />
<LAYERDEF id="2" visible="True" query="" />
<LAYERDEF id="1" visible="False" query="" />       
        </LAYERLIST>
        <MAPSERVICELIST/>   
      </DATAFRAME>
    </GET_LAYOUT>
  </REQUEST>
</PLOT>
as you see, <MAPSERVICELIST/>   is empty and <LAYERLIST> contains all <LAYERDEF> of <MAPSERVICEDEF>/<LAYERLIST> 
 The ones  of BASEMAP  are kept unchanged  but the ones of MAP1 are having a new attribute value for id.
Thanks four your help.
Regards.

You can implement very straightforward map in BizTalk like below:
If you are interested in XSLT of this map, I copied below which visual studio gave me when i validated the map:
<?xml version="1.0" encoding="UTF-16"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:var="http://schemas.microsoft.com/BizTalk/2003/var" exclude-result-prefixes="msxsl var" version="1.0">
<xsl:output omit-xml-declaration="yes" method="xml" version="1.0" />
<xsl:template match="/">
<xsl:apply-templates select="/PLOT" />
</xsl:template>
<xsl:template match="/PLOT">
<PLOT>
<REQUEST>
<GET_LAYOUT>
<PROPERTIES>
<MAPNAME>
<xsl:if test="REQUEST/GET_LAYOUT/PROPERTIES/MAPNAME/@name">
<xsl:attribute name="name">
<xsl:value-of select="REQUEST/GET_LAYOUT/PROPERTIES/MAPNAME/@name" />
</xsl:attribute>
</xsl:if>
<xsl:value-of select="REQUEST/GET_LAYOUT/PROPERTIES/MAPNAME/text()" />
</MAPNAME>
<xsl:value-of select="REQUEST/GET_LAYOUT/PROPERTIES/text()" />
</PROPERTIES>
<DATAFRAME>
<xsl:if test="REQUEST/GET_LAYOUT/DATAFRAME/@id">
<xsl:attribute name="id">
<xsl:value-of select="REQUEST/GET_LAYOUT/DATAFRAME/@id" />
</xsl:attribute>
</xsl:if>
<LAYERLIST>
<xsl:for-each select="REQUEST/GET_LAYOUT/DATAFRAME/MAPSERVICELIST/MAPSERVICEDEF">
<xsl:for-each select="LAYERLIST/LAYERDEF">
<LAYERDEF>
<xsl:if test="../../../../LAYERLIST/LAYERDEF/@id">
<xsl:attribute name="id">
<xsl:value-of select="../../../../LAYERLIST/LAYERDEF/@id" />
</xsl:attribute>
</xsl:if>
<xsl:if test="@id">
<xsl:attribute name="id">
<xsl:value-of select="@id" />
</xsl:attribute>
</xsl:if>
<xsl:if test="../../../../LAYERLIST/LAYERDEF/@visible">
<xsl:attribute name="visible">
<xsl:value-of select="../../../../LAYERLIST/LAYERDEF/@visible" />
</xsl:attribute>
</xsl:if>
<xsl:if test="@visible">
<xsl:attribute name="visible">
<xsl:value-of select="@visible" />
</xsl:attribute>
</xsl:if>
<xsl:if test="../../../../LAYERLIST/LAYERDEF/@query">
<xsl:attribute name="query">
<xsl:value-of select="../../../../LAYERLIST/LAYERDEF/@query" />
</xsl:attribute>
</xsl:if>
<xsl:if test="@query">
<xsl:attribute name="query">
<xsl:value-of select="@query" />
</xsl:attribute>
</xsl:if>
</LAYERDEF>
</xsl:for-each>
</xsl:for-each>
<xsl:value-of select="REQUEST/GET_LAYOUT/DATAFRAME/LAYERLIST/text()" />
</LAYERLIST>
<MAPSERVICELIST>
<xsl:text> </xsl:text>
</MAPSERVICELIST>
<xsl:value-of select="REQUEST/GET_LAYOUT/DATAFRAME/text()" />
</DATAFRAME>
<xsl:value-of select="REQUEST/GET_LAYOUT/text()" />
</GET_LAYOUT>
<xsl:value-of select="REQUEST/text()" />
</REQUEST>
</PLOT>
</xsl:template>
</xsl:stylesheet>
You can highlight the issue if you have any specific one.
