[sadiqmodan]

Hello, I have created one XSLT which is transforming one XML to another XML. Sample XML.

XSLT is

<xsl:stylesheet  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"  version="1.0">  <xsl:param name="NodeID"></xsl:param>  <xsl:param name="NodeType"></xsl:param>  <xsl:param name="NodeVirtual"></xsl:param>  <xsl:param name="NodeName"></xsl:param>  <xsl:param name="NodeTypeID"></xsl:param>  <xsl:param name="ParentID"></xsl:param>  <xsl:output indent="yes"/>  <xsl:template match="Answers">    <Node>	  <!--NodeID-->	  <xsl:element name="NodeID">	    <xsl:value-of select="$NodeID"/>	  </xsl:element>	  <!--NodeType-->	  <xsl:element name="NodeType">	    <xsl:value-of select="$NodeType"/>	  </xsl:element>	  <!--NodeTypeID-->	  <xsl:element name="NodeTypeID">	    <xsl:value-of select="$NodeTypeID"/>	  </xsl:element>	  <!--NodeVirtual-->	  <xsl:element name="NodeVirtual">	    <xsl:value-of select="$NodeVirtual"/>	  </xsl:element>	  <!--NodeVirtual-->	  <xsl:element name="NodeName">	    <xsl:value-of select="$NodeName"/>	  </xsl:element>	  <!--ParentID-->	  <xsl:element name="ParentID">	    <xsl:value-of select="$ParentID"/>	  </xsl:element>	  <xsl:apply-templates select="AnswerSet/Answer[1]"/>    </Node>  </xsl:template>  <xsl:template match="AnswerSet/Answer[not(@type = 'list') and not(@RegionName)]">    <xsl:element name="{@questionId}">	  <xsl:value-of select="."/>    </xsl:element>    <xsl:apply-templates select="following-sibling::Answer[1]"/>  </xsl:template>  <xsl:template match="AnswerSet/Answer[(@RegionName)]">    <xsl:element name="{@RegionName}">	  <xsl:element name="{@questionId}">	    <xsl:if test="@type = 'list'">		  <Items>		    <xsl:value-of select="."/>		  </Items>	    </xsl:if>	    <xsl:if test="not(@type = 'list')">		  <xsl:value-of select="."/>	    </xsl:if>	  </xsl:element>  	  <xsl:apply-templates select="." mode="Regionlist"/>      </xsl:element>    <xsl:variable name="next1" select="following-sibling::Answer[@RegionName = current()/@RegionName and @RepeatRegion != current()/@RepeatRegion][1]"/>    <xsl:if test="$next1">	  <xsl:apply-templates select="$next1"/>    </xsl:if>       <xsl:apply-templates select="following-sibling::Answer[not(@RegionName = current()/@RegionName)][1]"/>  </xsl:template>  <!--<xsl:template match="AnswerSet/Answer[(@RegionName)]" mode="RepeatRegionID">    <xsl:element name="{@RegionName}">	  <xsl:element name="{@questionId}">	    <xsl:if test="@type = 'list'">		  <Items>		    <xsl:value-of select="."/>		  </Items>	    </xsl:if>	    <xsl:if test="not(@type = 'list')">		  <xsl:value-of select="."/>	    </xsl:if>	  </xsl:element>	  <xsl:apply-templates select="." mode="Regionlist"/>    </xsl:element>     </xsl:template>-->  <xsl:template match="AnswerSet/Answer" mode="Regionlist">    <xsl:variable name="next" select="following-sibling::Answer[1][@RegionName = current()/@RegionName and @RepeatRegion = current()/@RepeatRegion]"/>    <xsl:if test="$next">	  <xsl:element name="{($next)[1]/@questionId}">	    <xsl:if test="($next)[1]/@type = 'list'">		  <Items>		    <xsl:value-of select="($next)[1]/node()[1]"/>		  </Items>	    </xsl:if>	    <xsl:if test="not(($next)[1]/@type = 'list')">		  <xsl:value-of select="($next)[1]/node()[1]"/>	    </xsl:if>	  </xsl:element>	  <xsl:apply-templates select="$next" mode="Regionlist"/>    </xsl:if>    </xsl:template>   <xsl:template match="AnswerSet/Answer[@type = 'list' and not(@RegionName)]">    <xsl:element name="{@questionId}">	  <Items>	    <xsl:value-of select="."/>	  </Items>	  <xsl:apply-templates select="." mode="list"/>    </xsl:element>    <xsl:apply-templates select="following-sibling::Answer[not(@questionId = current()/@questionId) and not(@RegionName)][1]"/>  </xsl:template>  <xsl:template match="AnswerSet/Answer" mode="list">    <xsl:variable name="next" select="following-sibling::Answer[1][@questionId = current()/@questionId]"/>    <xsl:if test="$next">	  <Items>	    <xsl:value-of select="$next"/>	  </Items>	  <xsl:apply-templates select="$next" mode="list"/>    </xsl:if>  </xsl:template></xsl:stylesheet>

When I apply above XSLT to sample XML it will transform like :

<?xml version="1.0" encoding="utf-8"?><Node>  <NodeID></NodeID>  <NodeType></NodeType>  <NodeTypeID></NodeTypeID>  <NodeVirtual></NodeVirtual>  <NodeName></NodeName>  <ParentID></ParentID>  <Name>testttttt123</Name>  <TesCal>1/26/2012 12:00:00 AM</TesCal>  <testPhoto>Node1216sadi20120113.JPG</testPhoto>  <Sam>    <Testrr>rr111</Testrr>    <Testrr1>123456</Testrr1>  </Sam>  <Sam>    <Testrr>rr1112</Testrr>    <Testrr1>456789</Testrr1>  </Sam>  <Sam>    <Testrr>rr1113</Testrr>    <Testrr1>4577855</Testrr1>  </Sam>  <Sam>    <Testrr></Testrr>    <Testrr1></Testrr1>  </Sam>  <Sam>    <Testrr></Testrr>    <Testrr1></Testrr1>  </Sam>  <testPhoto12>Node1216sadi20120113.JPG</testPhoto12>  <testPhoto12>Node1216sadi20120113.JPG</testPhoto12>  <testPhoto12>Node1216sadi20120113.JPG</testPhoto12>  <testPhoto12>Node1216sadi20120113.JPG</testPhoto12>  <testPhoto12>Node1216sadi20120113.JPG</testPhoto12></Node>

the proble is last node testPhoto12 is generated multiple time but it should be one time only because Questionid="TextPhoto12" is one time only in sample xml. Please can you provice better idea how to generate XSLT properly. Thanks in advance.
