In SAP PI I have xml files from rest services (web configurator) for which the fields can vary based on the product. For instance product A has a color, a height and a width and product B has a color, a height a width and a depth.
Example incoming XML:
<?xml version="1.0" encoding="UTF-8"?>
<Order>
<Products>
<Product>
<Color>Black</Color>
<Height>2000</Height>
<Width>1000</Width>
</Product>
</Products>
</Order>
To handle this 'generic' I want to convert the fields to some kind of key / value pair structure with an 1.0 XSL transformation.
Example required XML:
<?xml version="1.0" encoding="UTF-8"?>
<Order>
<Products>
<Product>
<Var>
<VarName>Color</VarName>
<VarValue>Black</VarValue>
</Var>
<Var>
<VarName>Height</VarName>
<VarValue>2000</VarValue>
</Var>
<Var>
<VarName>Width</VarName>
<VarValue>1000</VarValue>
</Var>
</Product>
</Products>
</Order>
I've found an article which describes it the other way around XSLT: Convert Name/Value pair and transform an XML
This is what Martin told you:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="Product/*">
<Var>
<VarName>
<xsl:value-of select="name()"/>
</VarName>
<VarValue>
<xsl:value-of select="."/>
</VarValue>
</Var>
</xsl:template>
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="Products">
<xsl:copy>
<xsl:for-each select="Product">
<Product>
<xsl:for-each select="./*">
<Var>
<VarName><xsl:value-of select="local-name()"/></VarName>
<VarValue><xsl:value-of select="."/></VarValue>
</Var>
</xsl:for-each>
</Product>
</xsl:for-each>
</xsl:copy>
</xsl:template>
