Hey guys,
I have a problem extracting some data out of this XML file:
<?xml version="1.0" encoding="UTF-8"?>
<ph:Graphs xmlns:ph="http://www.merge.something.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<ph:Graph name="mass_spring_mo">
<ph:Element id="0" type="Fixed">
<ph:Port id="1" type="port">
<ph:Attribute>
<ph:AttributeField name="type" value="string"/>
<ph:AttributeField name="name" value="type"/>
<ph:AttributeField name="value" value="flange"/>
</ph:Attribute>
</ph:Port>
</ph:Element>
<ph:Element id="2" type="Spring">
<ph:Attribute>
<ph:AttributeField name="type" value="int"/>
<ph:AttributeField name="name" value="s_rel0"/>
<ph:AttributeField name="value" value="5"/>
</ph:Attribute>
<ph:Attribute>
<ph:AttributeField name="type" value="int"/>
<ph:AttributeField name="name" value="par_s_rel0"/>
<ph:AttributeField name="value" value="5"/>
</ph:Attribute>
<ph:Port id="3" type="port">
<ph:Attribute>
<ph:AttributeField name="type" value="string"/>
<ph:AttributeField name="name" value="type"/>
<ph:AttributeField name="value" value="flange_a"/>
</ph:Attribute>
</ph:Port>
<ph:Port id="4" type="port">
<ph:Attribute>
<ph:AttributeField name="type" value="string"/>
<ph:AttributeField name="name" value="type"/>
<ph:AttributeField name="value" value="flange_b"/>
</ph:Attribute>
</ph:Port>
</ph:Element>
<ph:Element id="5" type="Mass">
<ph:Port id="6" type="port">
<ph:Attribute>
<ph:AttributeField name="type" value="string"/>
<ph:AttributeField name="name" value="type"/>
<ph:AttributeField name="value" value="flange_a"/>
</ph:Attribute>
</ph:Port>
</ph:Element>
<ph:Edge id="7" sourceid="1" targetid="3"/>
<ph:Edge id="8" sourceid="4" targetid="6"/>
</ph:Graph>
</ph:Graphs>This is the solution I found. I still have problems to figure out how to handle the <attributes> of a ph:Element if there are more than one but the output should look like (s_rel0 = 10, par_s_rel0 = 5) and not like (s_rel0 = 5)(par_s_rel0 = 5).
And the second conection should consist of flange_b and not of flange_a. I searched for while the mistake but could not find it.

</xsl:text>
</xsl:template>
</xsl:stylesheet>The disired output should look like this:
model mass_spring_mo
Components.Fixed fixed1;
Components.Spring spring2(s_rel0 = 10, par_s_rel0 = 5);
Components.Mass mass5;
equation
connect(fixed1.flange,spring2.flange_a);
connect(spring2.flange_b,mass5.flange_a);
end mass_spring_mo;Thanks in advance.
