Hello,
I have this xml file which in it has a recursive inner node:
Code:
<part_structure>
<assembly>
<part>
<part ref="PART1"/>
</part>
<id>PART1</id>
<find>0010C</find>
<quantity>0</quantity>
<usage>X</usage>
<level>0</level>
<childs>
<partnode>
<part>
<part ref="PART2"/>
</part>
<id>PART2</id>
<find>56900</find>
<quantity>1</quantity>
<usage>Standard</usage>
<level>1</level>
</partnode>
<partnode>
<part>
<part ref="PART3"/>
</part>
<id>PART3</id>
<find>69T1A</find>
<quantity>1</quantity>
<usage>Standard</usage>
<level>1</level>
</partnode>
<assembly>
<part>
<part ref="PART4"/>
</part>
<id>PART4 </id>
<find>00105</find>
<quantity>1</quantity>
<usage>Standard</usage>
<level>1</level>
<childs>
<partnode>
<part>
<part ref="PART5"/>
</part>
<id>PART5</id>
<find>6221A</find>
<quantity>1</quantity>
<usage>Standard</usage>
<level>2</level>
</partnode>
</childs>
</assembly>
</childs>
</assembly>
</part_structure>
as can be seen the childs node can have partnode and assembly, the assembly can then have a recursive structure. So in theory the assembly in the child node can be something like
Code:
<assembly>
<part>
<part ref="PART4"/>
</part>
<id>PART4 </id>
<find>00105</find>
<quantity>1</quantity>
<usage>Standard</usage>
<level>1</level>
<childs>
<partnode>
<part>
<part ref="PART5"/>
</part>
<id>PART5</id>
<find>6221A</find>
<quantity>1</quantity>
<usage>Standard</usage>
<level>2</level>
</partnode>
<assembly>
<part>
<part ref="PART41"/>
</part>
<id>PART4 </id>
<find>00105</find>
<quantity>1</quantity>
<usage>Standard</usage>
<level>1</level>
<childs>
<partnode>
<part>
<part ref="PART51"/>
</part>
<id>PART5</id>
<find>6221A</find>
<quantity>1</quantity>
<usage>Standard</usage>
<level>2</level>
</partnode>
<assembly>
....
</assembly>
</childs>
</assembly>
</childs>
</assembly>
I have written this code:

this gives me the following result:
Code:
<part-structure>
<assembly id="PART1" find="0010C" quantity="0" usage="X" level="0">
<part id="PART2" find="56900" quantity="1" usage="Standard" level="1"/>
<part id="PART3" find="69T1A" quantity="1" usage="Standard" level="1"/>
PART2
56900
1
Standard
1
PART3
69T1A
1
Standard
1
<assembly id="PART4" find="00105" quantity="1" usage="Standard" level="1">
PART4
00105
1
Standard
1
<part id="PART5" find="6221A" quantity="1" usage="Standard" level="2"/>
PART5
6221A
1
Standard
2
</assembly>
</assembly>
</part-structure>
The result is correct and it also works when there is inner assembly nodes, the problem is with the output of the values of the nodes. first I tried to get rid of there by writing empty templates, at the end of the xslt code, but I realised that if there are recursive inner assembly nodes this won't help at all.
So my question is how can I get rid of these node values?
