how to transform with this source and target document? - xslt

Question

I have the XML source file in SVG present like this:
<svg>
<g id='a001' class='pools'>
<g id='b001' class='pool' name='Proc111'>
<g id='c001' class='lane' name='User111' PoolID='b001'>
<g id='d001' class='startevent' name='startevent111' LaneID='c001'></g>
</g>
<g id='c002' class='lane' name='User222' PoolID='b001'>
<g id='d002' class='gateway' name='gateway111' LaneID='c002'></g>
</g>
</g>
<g id='b002' class='pool' name='Proc222'>
<g id='c003' class='lane' name=' customer ' PoolID=' b002'>
<g id='d003' class='endevent' name='endevent111' LaneID='c003'> </g>
</g>
</g>
</g>
<g id='a002' class='messageflows'/>
</svg>
i wanna tranform to XML target as following document:
<process id='a001' name='proc111'>
<laneset>
<lane name='User111'/>
<lane name='User222'/>
</laneset>
<startevent id='d001' name='startevent111'/>
<gateway id='d002' name='gateway111'/>
</process>
<process id='a002' name='proc222'>
<laneset>
<lane name='customer'/>
</laneset>
<endevent id='d003' name='endevent111'/>
</process>
I had tried with some transformation but it was unsuccessfull...My solution is create the main template; and inside the main template(process template), I call for the other templates which are starteventtemplate, endeventtemplate, gateway template, etc. However, in the target document, I get all childrent which are present the same for each parent elements('process').
Because the real file is bigger than this example with a lot of elements...So, I've carried out the main problem to apply for the remaining elements.

Using the following stylesheet you can generate the desired output:
<?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:strip-space elements="*"/>
<xsl:template match="/">
<processes>
<xsl:apply-templates />
</processes>
</xsl:template>
<xsl:template match="g[#class='pool']" >
<process>
<laneset>
<xsl:apply-templates mode="laneset" />
</laneset>
<xsl:apply-templates mode="startevent" />
<xsl:apply-templates mode="gateway" />
</process>
</xsl:template>
<xsl:template match="g[#class='lane']" mode="laneset">
<lane name="{#name}"/>
</xsl:template>
<xsl:template match="g[#class='startevent']" mode="startevent">
<startevent id="{#id}" name="{#name}"/>
</xsl:template>
<xsl:template match="g[#class='gateway']" mode="gateway">
<gateway id="{#id}" name="{#name}"/>
</xsl:template>
</xsl:stylesheet>

This stylesheet:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="g[#class='pools']">
<processes>
<xsl:apply-templates />
</processes>
</xsl:template>
<xsl:template match="g[#class='pool']" priority="1">
<process id="{#id}" name="{#name}">
<laneset>
<xsl:apply-templates/>
</laneset>
<xsl:apply-templates select="*/*"/>
</process>
</xsl:template>
<xsl:template match="g/g">
<xsl:element name="{#class}">
<xsl:copy-of select="#id[../#class != 'lane']|#name"/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
Output:
<processes>
<process id="b001" name="Proc111">
<laneset>
<lane name="User111" />
<lane name="User222" />
</laneset>
<startevent id="d001" name="startevent111" />
<gateway id="d002" name="gateway111" />
</process>
<process id="b002" name="Proc222">
<laneset>
<lane name=" customer " />
</laneset>
<endevent id="d003" name="endevent111" />
</process>
</processes>
