Want to write XSLT for a XML to get a tree structure?

I have got some XML like this; I want to be writing a XSLT. Where I can extract the attribute V. And produce a Tree Structure like this.

........Customer Location Images
              .
              .
              . Service3.

  <PV V="PS:Product Category:Product1" L="" H="" C="327" /> 
  <PV V="PS:Financial Product Images:Product2" L="" H="" C="173" />

  <PV V="Other:Customer Location Images:Service 3" L="" H="" C="98" /> 

Can anybody please hel开发者_StackOverflowp me i am very new to XSLT

You could use this XSLT

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
    <xsl:template match="/wrapper">
        <wrapper2>
            <xsl:apply-templates select="PV[starts-with(@V,'PS')]"/>
            <xsl:apply-templates select="PV[starts-with(@V,'Other')]"/>
        </wrapper2>
    </xsl:template>

    <xsl:template match="//PV">
        <xsl:variable name="elementName1" select="substring-before(./@V,':')"/>
        <xsl:variable name="elementName23" select="substring-after(./@V,':')"/>
        <xsl:variable name="elementName2"
            select="translate(substring-before($elementName23,':'), ' ', '_')"/>
        <xsl:variable name="elementName3"
            select="translate(substring-after($elementName23,':'), ' ', '_')"/>

        <xsl:if test="not($elementName1 = '')">
            <xsl:element name="{$elementName1}">
                <xsl:element name="{$elementName2}">
                    <xsl:element name="{$elementName3}"> </xsl:element>
                </xsl:element>
            </xsl:element>
        </xsl:if>
    </xsl:template>
</xsl:stylesheet>

A tag name cannot have whitespaces so you need to replace them by some other character. This is done here by replacing spaces by '_'.
