Re: Using XSLT to merge two XML Nodes

Hi,
        Please use the below stylesheet to achieve what you want.


<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:n1="urn:n1.nmspace">

<xsl:output method="xml"></xsl:output>

<xsl:key name="book1" match="BookList1/Book" use="@id"/>
<xsl:key name="book2" match="BookList2/Book" use="@id"/>


             <xsl:template match="/">

             <xsl:variable name="allbooks" select="/AllBooks/*"/>

            <xsl:apply-templates select="$allbooks/Book">
            <xsl:sort select="@id"/>
            </xsl:apply-templates>

             </xsl:template>

      <xsl:template match="Book">

      <xsl:call-template name="book1"/>

       </xsl:template>

 <xsl:template name="book1">

  <xsl:variable name="books_1" select="key('book1', @id)"/>
  <xsl:variable name="books_2" select="key('book2', @id)"/>

 <xsl:if test="$books_1">
      <xsl:copy-of select="key('book1', @id)"/>
</xsl:if>
<xsl:if test="not(key('book1', @id))">
<xsl:text>Not Found
</xsl:text>
</xsl:if>
<xsl:if test="not(key('book2', @id))">
<xsl:text>Not Found
</xsl:text>
</xsl:if>
  <xsl:if test="$books_2 and not($books_1)">
      <xsl:copy-of select="key('book2', @id)"/>
</xsl:if>

 </xsl:template>


</xsl:stylesheet>

Hi,

I have a document with two nodes that I have to merge:

<AllBooks>
 <BookList1>
   <Book id=3D"1" upc=3D"1" someotherID=3D"booklist1" salePrice=3D"1"/>
   <Book id=3D"3" upc=3D"3" someotherID=3D"booklist1" salePrice=3D"3"/>
   <Book id=3D"4" upc=3D"4" someotherID=3D"booklist1" salePrice=3D"4"/>
 </BookList1>
 <BookList2>
   <Book id=3D"2" upc=3D"2" someotherID=3D"booklist2" salePrice=3D"2"/>
   <Book id=3D"3" upc=3D"3" someotherID=3D"booklist2" salePrice=3D"3"/>
   <Book id=3D"4" upc=3D"4" someotherID=3D"booklist2" salePrice=3D"4"/>
   <Book id=3D"5" upc=3D"5" someotherID=3D"booklist2" salePrice=3D"5"/>
 </BookList2>
</AllBooks>

My output needs to be:

<AllBooks>
 <BookList>
   <Book id=3D"1" upc=3D"1" someotherID=3D"booklist1" salePrice=3D"1"/>
   <NotFound/>
   <NotFound/>
   <Book id=3D"2" upc=3D"2" someotherID=3D"booklist2" salePrice=3D"2"/>
   <Book id=3D"3" upc=3D"3" someotherID=3D"booklist1" salePrice=3D"3"/>
   <Book id=3D"3" upc=3D"3" someotherID=3D"booklist2" salePrice=3D"3"/>
   <Book id=3D"4" upc=3D"4" someotherID=3D"booklist1" salePrice=3D"4"/>
   <Book id=3D"4" upc=3D"4" someotherID=3D"booklist2" salePrice=3D"4"/>
   <NotFound/>
   <Book id=3D"5" upc=3D"5" someotherID=3D"booklist2" salePrice=3D"5"/>
