Dear community,
I have an XML-structured message in my CPI flow like the following and want to delete all except the first B3 node (and their children). How can I best do this? I have tried the 'filter' in CPI without success, because CPI does not allow the "ancestor-or-self::div" syntax to access parents. "::" is reserved for namespaces (error: namespace prefix ancestor-or-self not defined in name space mapping). Is there any way to escape these special characters? Or is there a better way to achieve the desired output?
<A>
<B1>value</B1>
<B2>value</B2>
<B3>
<C1>
<D1>value</D1>
<D1>value</D1>
</C1>
</B3>
<B3>
<C2>
<D2>value</D2>
<D2>value</D2>
</C2>
</B3>
</A>
Desired output:
<A>
<B1>value</B1>
<B2>value</B2>
<B3>
<C1>
<D1>value</D1>
<D1>value</D1>
</C1>
</B3>
</A>
