How can I use loop in graphical message mapping

Posted on Aug 11, 2009 at 10:34 AM 146 Views

The source input XML is like:

<bookstore>

<book>

<item1>xxx</item1>

<item2>yyy</item2>

</book>

<book>

<item1>zzz</item1>

<item2>www</item2>

</book>

........

</bookstore>

I want to create an output XML like

<output>

<item>

<item1>xxx</item1>

<item2>yyy</item2>

</item>

<item>

<item1>xxx</item1>

<item2>www</item2>

</item>

<item>

<item1>zzz</item1>

<item2>www</item2>

</item>

<item>

<item1>xxx</item1>

<item2>yyy</item2>

</item>

.....

</output>

That means I want to do permutation and combination for all <item1> <item2> under <book>.

Of course I can write a customer function to do it, but I want to basically use the buildin functions to do the graphical message mapping for this.

Any idea? thank you.

    Hi WuDao,

    This is not possible without using UDF because you would need to combine the contexts i.e item a has two, item b has two..so the output should have four contexts (item a1, item a1, item a2, item a2) for item1

    hope this helps,

    Can you explain it more clearly you requeriment ?

    Because on your 3st target the Item1 is ZZZ and the and the 4th is XXX I guess maybe has a specific rule.

    In other case if value is "XXX" you need to write an UDF function to replicate the value ,however your target Item is generated in based your mapping or is a static structure.
