XML Parent Child Console Using XSLT

Question

INPUT XML:

<?xml version="1.0" encoding="ISO-8859-1"?> <system> <map name="Map"> <map name="Map1"> <color>Map1 is red colored</color> <shape>Map1 is square shaped</shape> </map> <map name="Map2"> <color>Map2 is green colored</color> <map name="Tap1"> <color>Tap1 is yellow colored</color> <speed>Tap1 is very fast</speed> </map> <map name="Tap2"> <speed>Tap2 is very slow</speed> </map> </map> </map> </system> 

DESIRED OUTPUT:

 <?xml version="1.0" encoding="ISO-8859-1"?> <system> <map name="Map+Map1"> <color>Map1 is red colored</color> <shape>Map1 is square shaped</shape> </map> <map name="Map+Map2"> <color>Map2 is green colored</color> </map> <map name="Map+Map2+Tap1"> <color>Tap1 is yellow colored</color> <speed>Tap1 is very fast</speed> </map> <map name="Map+Map2+Tap2"> <speed>Tap2 is very slow</speed> </map> 

Current OUTPUT:

 <system> <map name="Map1"/> <map name="Map1"/> <map name="Map2"/> <map name="Map2.Tap1"/> <map name="Map2.Tap1"/> <map name="Map2.Tap2"/> </system> 

Current XSL stylesheet:

 <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="xml" indent="yes"/> <xsl:template match="map[@name]"> <xsl:apply-templates mode="next"> <xsl:with-param name="name" select="''" /> </xsl:apply-templates> </xsl:template> <xsl:template match="map[@name]" mode="next"> <xsl:param name="name" /> <xsl:apply-templates mode="next"> <xsl:with-param name="name" select="concat($name,'.',@name)" /> </xsl:apply-templates> </xsl:template> <xsl:template match="*[not(*)]" mode="next"> <xsl:param name="name" /> <xsl:element name="map"> <xsl:attribute name="name"> <xsl:variable name="nameLength" select="string-length($name)-1"/> <xsl:value-of select="substring($name,2,$nameLength)"/> </xsl:attribute> </xsl:element> </xsl:template> <xsl:template match="@*|node()|*"> <xsl:copy> <xsl:apply-templates select="@*|node()|*"/> </xsl:copy> </xsl:template> </xsl:stylesheet> 

I'm just new to XSL. I talked a lot on the Internet and tried to solve this problem. But I failed. Someone please help me get the correct xsl code to achieve the same. You are welcome.

Answer 1

You can try something like this:

 <?xml version="1.0" encoding="utf-8" ?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="xml" indent="yes"/> <xsl:template match="map" mode="concat" > <xsl:param name="names" select="''" /> <xsl:variable name="newName" select="concat($names,@name)" /> <xsl:copy> <xsl:attribute name ="name"> <xsl:value-of select="$newName"/> </xsl:attribute> <xsl:copy-of select="*[name() != 'map']"/> </xsl:copy> <xsl:apply-templates select="map" mode ="concat"> <xsl:with-param name="names" select="concat($newName,'+')" /> </xsl:apply-templates> </xsl:template> <xsl:template match="*" > <xsl:copy> <xsl:apply-templates select="map" /> </xsl:copy> </xsl:template> <xsl:template match="/*/map"> <xsl:apply-templates select="map" mode="concat"> <xsl:with-param name ="names" select="concat(@name,'+')" /> </xsl:apply-templates> </xsl:template> </xsl:stylesheet> 

In this small example, my mode is not needed, but it will be useful if the xlst file grows. Otuput:

 <?xml version="1.0"?> <system> <map name="Map+Map1"> <color>Map1 is red colored</color> <shape>Map1 is square shaped</shape> </map> <map name="Map+Map2"> <color>Map2 is green colored</color> </map> <map name="Map+Map2+Tap1"> <color>Tap1 is yellow colored</color> <speed>Tap1 is very fast</speed> </map> <map name="Map+Map2+Tap2"> <speed>Tap2 is very slow</speed> </map> </system> 

Answer 2

Here is another option ...

XML input

 <map name="Map"> <map name="Map1"> <color>Map1 is red colored</color> <shape>Map1 is square shaped</shape> </map> <map name="Map2"> <color>Map2 is green colored</color> <map name="Tap1"> <color>Tap1 is yellow colored</color> <speed>Tap1 is very fast</speed> </map> <map name="Tap2"> <speed>Tap2 is very slow</speed> </map> </map> </map> 

XSLT 1.0

 <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output indent="yes"/> <xsl:strip-space elements="*"/> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:template match="/"> <system><xsl:apply-templates/></system> </xsl:template> <xsl:template match="map"> <xsl:apply-templates/> </xsl:template> <xsl:template match="map[*[not(self::map)]]"> <xsl:copy> <xsl:apply-templates select="@*"/> <xsl:attribute name="name"> <xsl:for-each select="ancestor-or-self::map[@name]"> <xsl:if test="ancestor::map[@name]">+</xsl:if> <xsl:value-of select="@name"/> </xsl:for-each> </xsl:attribute> <xsl:apply-templates select="node()[not(self::map)]"/> </xsl:copy> <xsl:apply-templates select="map"/> </xsl:template> </xsl:stylesheet> 

XML output

 <system> <map name="Map+Map1"> <color>Map1 is red colored</color> <shape>Map1 is square shaped</shape> </map> <map name="Map+Map2"> <color>Map2 is green colored</color> </map> <map name="Map+Map2+Tap1"> <color>Tap1 is yellow colored</color> <speed>Tap1 is very fast</speed> </map> <map name="Map+Map2+Tap2"> <speed>Tap2 is very slow</speed> </map> </system> 

Also, if you can use XSLT 2.0, you can replace xsl:attribute with this:

 <xsl:attribute name="name" select="string-join(ancestor-or-self::map/@name,'+')"/>
