Mapping challenge !! Generate target for unique combination of source field

Question

Hi,
I/P:
<Segement1>
<Article>1</Article>
</Segement1>
<Segement1>
<Article>2</Article>
</Segement1>
<Segement2>
<StoreNum>12</StoreNum>
<StoreNum>13</StoreNum>
<StoreNum>14</StoreNum>
</Segement2>
and the output should be like for every unique combination of Article and StoreNum I have to create a target node and the corresponding values in that node: (So in this case the o/p node will come 6 times)
<Detail>
<Article>1</Article>
<StoreNum>12</StoreNum>
</Detail>
<Detail>
<Article>1</Article>
<StoreNum>13</StoreNum>
</Detail>
<Detail>
<Article>2</Article>
<StoreNum>14</StoreNum>
</Detail>
Can anybody please suggest a solution ?

Answer 1

articleremovecontext-sortsplibyvalue(valuechange)-collapsecontext
UDF---details
storenumsort-splitbyvalue(valuechange)--collapsecontext
mapping of the elements inside details node can be achieved using UDF or standard function also.
UDF2
for(int i=0;i<var1.length;i++)
for(int j=0;j<var2.length;j++)
result.addValue(var1<i>);
result.addContextchange();
repeat the same mapping for Article(target filed) using udf2 as mentioned above for details...
UDF3:
for(int i=0;i<var1.length;i++)
for(int j=0;j<var2.length;j++)
result.addValue(var2<i>);
result.addContextchange();
repeat the same mapping for Storenum(target filed) using udf3 as mentioned above for details...
Note: check for syntax errors.....
