Tranform to expect xml file

metinhoclam · July 27th, 2010, 06:36 PM

So sorry...Mr.mhkay.......I've edited my source document. Could you help me fix the transformation document?
I have the XML source file that presents like this:

Code:

<process id='a001' name='proc111'>

  <laneset>
   <lane id='c001' name='User111'>
     <referenceElements>d001</referenceElements>
   </lane>
   <lane id='c002' name='User222'/>
     <referenceElements>d002</referenceElements>
    </lane>
  </laneset>

  <startevent id='d001' name='startevent111'/>
  <gateway id='d002' name='gateway111'/>

</process>

  <process id='a002' name='proc222'>
  <laneset>
    <lane id='c001' name='customer'>
       <referenceElements>d003</referenceElements>
    </lane>
  </laneset>
  <endevent id='d003' name='endevent111'/>

</process>

-----------------------------------------------

i wanna tranform to XML target as following document:

Code:

<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>
</svg>

------------------
My transformation file:
---------

Code:

<xsl:template match="/">
	<svg>
	<xsl:apply-templates/>						
	</svg>		
</xsl:template>
<xsl:template match="process">
  <g id="{@id}" name="{@name}" class="POOL">
     <xsl:apply-templates select="laneset/lane"/>
  </g>
</xsl:template>

<xsl:template match="lane">
  <g id="{@id}" class="LANE" name="{@name}" PoolID="parent::current()/@id">
     <xsl:variable name="p" select="count(preceding-sibling::lane)+1"/>
     <xsl:variable name="ref" select="ancestor::process/*[$p+1]"/>
     <xsl:apply-templates select="$ref"/>
  </g>
</xsl:template>

<xsl:template match="startevent">
  <g id="{@id}" class="startevent" name="{@name}"   LaneID="{parent::current()/@id}"/>
</xsl:template>
<xsl:template match="endevent">
  <g id="{@id}" class="endevent" name="{@name}"   LaneID="{parent::current()/@id}"/>
</xsl:template>
<xsl:template match="gateway">
  <g id="{@id}" class="gateway" name="{@name}"   LaneID="{parent::current()/@id}"/>
</xsl:template>
</xsl:stylesheet>

Could you see my problems?

It doesn't look difficult, but I'm not sure I fully understand the requirement. Where does the LaneID c001 come from? Why is startevent111 associated with user111 and gateway111 with user222 - is it simply a positional relationship?

You'll want a set of template rules something like this:

Code:

<xsl:template match="process">
  <g id="{@id}" name="{@name}" class="pool">
     <xsl:apply-templates select="laneset/lane"/>
  </g>
</xsl:template>

<xsl:template match="lane">
  <g id="{???}" class="lane" name="{@name}" PoolID="{???}">
     <xsl:variable name="p" select="count(preceding-sibling::lane)+1"/>
     <xsl:variable name="ref" select="ancestor::process/*[$p+1]"/>
     <xsl:apply-templates select="$ref"/>
  </g>
</xsl:template>

<xsl:template match="startevent">
  <g id="{@id}" class="startevent" name="{@name}" LaneID="{???}"/>
</xsl:template>

The ??? are places where I can't work out how you get the output value.

The process has the same name with the pool. Inside the pool is a lot of lanes. For each lane, there are some activities/notations such as: startevent, endevent, gateway, and the other notation of BPMN. So, each lane have to indicate its PoolID that is referenced from the id of Pool where lane is located.
Similarly, each activities/notations inside the lane have to reveal LaneID that is referenced from the id of Lane where activities/notation is located.

The main thing is how each element references to its parent..
