Transforming XML Attributes into XML Elements - xslt

Question

I have the following XML input:
<?xml version="1.0" encoding="utf-8"?>
<DOCUMENT>
<EXTERNALFILES>
<PRIMARYFILE FileName="C:\MSSB\POC\Exports\13f78581-1501-4dd0-8cf3-a5a300ba4083\121110-26-2001031100092.TIF" />
</EXTERNALFILES>
<OCRTEXTFILES />
<DOCUMENTINDEX Name="A2iA_CheckAmount">3304.49</DOCUMENTINDEX>
<DOCUMENTINDEX Name="A2iA_CheckCAR">3304.49</DOCUMENTINDEX>
<DOCUMENTINDEX Name="A2iA_CheckCodeline_OnUs1">28557833</DOCUMENTINDEX>
<DOCUMENTINDEX Name="A2iA_CheckCodeline_Transit">031100092</DOCUMENTINDEX>
<DOCUMENTINDEX Name="A2iA_CheckDate">10-26-2001</DOCUMENTINDEX>
<DOCUMENTINDEX Name="A2iA_CheckLAR">3304.49</DOCUMENTINDEX>
<DOCUMENTINDEX Name="A2iA_CheckNumber">1211</DOCUMENTINDEX>
<DOCUMENTINDEX Name="A2iA_CheckPayeeName">BCBSD</DOCUMENTINDEX>
<DOCUMENTINDEX Name="CheckPayerName">SOFTPRO NORTH AMERICA, INC.</DOCUMENTINDEX>
</DOCUMENT>
I need to transform this into the following output:
<?xml version="1.0" encoding="utf-8"?>
<DOCUMENT>
<A2iA_CheckAmount>3304.49</A2iA_CheckAmount>
<A2iA_CheckCAR>3304.49</A2iA_CheckCAR>
<A2iA_CheckLAR>3304.49</A2iA_CheckLAR>
<A2iA_CheckAccountNumber>28557833</A2iA_CheckAccountNumber>
<A2iA_CheckRoutingNumber>031100092</A2iA_CheckRoutingNumber>
<A2iA_CheckNumber>1211</A2iA_CheckNumber>
<A2iA_CheckAmount>3304.49</A2iA_CheckAmount>
<A2iA_CheckPayeeName>BCBSD</A2iA_CheckPayeeName>
<CheckPayerName>SOFTPRO NORTH AMERICA, INC</CheckPayerName>
</DOCUMENT>
I am using the following XSLT code:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:value-of select="concat('<DOCUMENT>')"/>
<xsl:template match="/*">
<xsl:for-each select="DOCUMENT/DOCUMENTINDEX/#*">
<xsl:value-of select="concat('<', name(), '>', ., '</', name(), '>')"/>
</xsl:for-each>
<xsl:value-of select="concat('</DOCUMENT>')"/>
</xsl:template>
I tested this with an online XSLT Tester and it threw a non-descriptive error. I am new to XSLT Transformation. Any help will be greatly appreciated. Thank You.

Answer 1

One possibility to achieve this is the following simple one(EDITED):
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes" />
<xsl:template match="/DOCUMENT">
<xsl:element name="Document">
<xsl:apply-templates />
</xsl:element>
</xsl:template>
<xsl:template match="DOCUMENTINDEX">
<xsl:element name="{#Name}">
<xsl:value-of select="text()" />
</xsl:element>
</xsl:template>
</xsl:stylesheet>
It gives the output (EDITED)
<Document>
<A2iA_CheckAmount>3304.49</A2iA_CheckAmount>
<A2iA_CheckCAR>3304.49</A2iA_CheckCAR>
<A2iA_CheckCodeline_OnUs1>28557833</A2iA_CheckCodeline_OnUs1>
<A2iA_CheckCodeline_Transit>031100092</A2iA_CheckCodeline_Transit>
<A2iA_CheckDate>10-26-2001</A2iA_CheckDate>
<A2iA_CheckLAR>3304.49</A2iA_CheckLAR>
<A2iA_CheckNumber>1211</A2iA_CheckNumber>
<A2iA_CheckPayeeName>BCBSD</A2iA_CheckPayeeName>
<CheckPayerName>SOFTPRO NORTH AMERICA, INC.</CheckPayerName>
</Document>
