Question

I have the following XML sturture in my project. I need to write somthing that transposes repeating nodes to make a flat stuture

<bookstore>
  <book >
    <title lang="en">Everyday Italian</title>
    <author>Giada De Laurentiis</author>
    <year>2005</year>
    <price>30.00</price>
  </book>
  <book >
    <title lang="en">Harry Potter</title>
    <author>J K. Rowling</author>
    <year>2005</year>
    <price>29.99</price>
  </book>
  <book>
    <title lang="en">Learning XML</title>
    <author>Erik T. Ray</author>
    <year>2003</year>
    <price>39.95</price>
  </book>
</bookstore>

I want to flaten the sturture like this

<bookstore>

    <bookonetitle lang="en">Everyday Italian</bookonetitle>
    <bookoneauthor>Giada De Laurentiis</bookoneauthor>
    <bookoneyear>2005</bookoneyear>
    <bookoneprice>30.00</bookoneprice>


    <booktwotitle lang="en">Harry Potter</booktwotitle>
    <booktwoauthor>J K. Rowling</booktwoauthor>
    <booktwoyear>2005</booktwoyear>
    <booktwoprice>29.99</booktwoprice>

    <bookthreetitle lang="en">Learning XML</bookthreetitle>
    <bookthreetitle>Erik T. Ray</bookthreetitle>
    <bookthreetitle>2003</bookthreetitle>
    <bookthreetitle>39.95</bookthreetitle>



</bookstore>

Your output structure strikes me as being very awkward. You might like to reconsider it. But in any case, this XSLT 1.0 style-sheet…

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" omit-xml-declaration="yes" />
<xsl:strip-space elements="*" />

<xsl:template match="@*|node()">
  <xsl:copy>
    <xsl:apply-templates select="@*|node()"/>
  </xsl:copy>
</xsl:template>

<xsl:template match="book">
  <xsl:apply-templates select="node()"/>
</xsl:template>

<xsl:template match="book/*">
  <xsl:element name="book-{count(../preceding-sibling::book)+1}-{local-name()}">
    <xsl:apply-templates select="@*|node()"/>
  </xsl:element>
</xsl:template>

</xsl:stylesheet>

…will transform your sample input into…

<bookstore>
  <book-1-title lang="en">Everyday Italian</book-1-title>
  <book-1-author>Giada De Laurentiis</book-1-author>
  <book-1-year>2005</book-1-year>
  <book-1-price>30.00</book-1-price>
  <book-2-title lang="en">Harry Potter</book-2-title>
  <book-2-author>J K. Rowling</book-2-author>
  <book-2-year>2005</book-2-year>
  <book-2-price>29.99</book-2-price>
  <book-3-title lang="en">Learning XML</book-3-title>
  <book-3-author>Erik T. Ray</book-3-author>
  <book-3-year>2003</book-3-year>
  <book-3-price>39.95</book-3-price>
</bookstore>
