XSL lookup from a properties (csv) file - xslt

Question

I have an XML which needs to be formatted to a CSV. I have chosen XSL to do achieve this. In addition to the XML file, I have a Properties file which needs to be looked through for getting the values for the variables defined in the XML.
Can any one help me in how to do the lookups via an XSL using an external csv file?
CSV file after transformation:
Article.AclFlag|%field.Article.AclFlag.name|false|true|true|||||||||||master-data|%category.MasterData|Integer||0|||Enum.Acls|%enum.Acls.name|%enum.Acls.entry.0;%enum.Acls.entry.1;%enum.Acls.entry.2;%enum.Acls.entry.3;%enum.Acls.entry.4;%enum.Acls.entry.5;%enum.Acls.entry.6;|0;1;2;3;4;5;6;|0;1;2;3;4;5;6;|Article|%entity.Article.name|Product2G Variant

The csv file is also not formatted well.

Any help is much appreciated.

Answer 1

Given that your properties are of this form
<entry key="field.Article.AclFlag.name">Object right type</entry>
You can define a key to look up entry elements by their key attribute, and I see such a key already exists in your XSLT
<xsl:key name="k1" match="entry" use="#key"/>
Next, ensure you have a variable reference to your external XML document
<xsl:variable name="map-doc" select="document('../transform/Properties.properties.xml')"/>
Then, to look up a value from the properties you can do this (obviously replacing the second argument with the actual value you want to look up):
<xsl:variable name="test" select="'enum.Acls.name'" />
<xsl:value-of select="key('k1', $test, $map-doc)" />
Note this form of the key function, with a third parameter, is only valid in XSLT 2.0. If you were to do <xsl:value-of select="key('k1', $test) />, it would look for the value in the input XML, not your properties XML.
In XSLT 1.0 you could do this to change the document context for the key
<xsl:variable name="test" select="'enum.Acls.name'" />
<xsl:for-each select="$map-doc">
<xsl:value-of select="key('k1', $test)" />
</xsl:for-each>
Alternatively, do it without a key
<xsl:variable name="test" select="'enum.Acls.name'" />
<xsl:value-of select="$map-doc//entry[#key=$test]" />
