xml copy with text substitution from map P2: problem with text outside CDATA

mancocapac · January 16th, 2012, 03:49 PM

Hi,
I previously posted under [xml copy with text substitution from map] and with
the help of folks here i got a working transform. However, I have discovered
one error. I am using a map to translates UIDs to text values, it works for
elements found in CDATA that have been decoded using saxon.parse() but
does not work for elements that were outside the CDATA.

I hope you can set me figure this out, it has been driving my crazy for 2 days.

Thanks in advance,
Tim

In the example below see: sEventDefinitionID (ouside CDATA) and
ENTITYTYPEID (inside CDATA) both have the same UID value.

From the Console output below I have verified the following:
The UID [b02fb601b98a47ce8de32dbb157fb2a2] is in the map.
It doesn't have extra characters.
It is going thru the mapping template.
After passing thru the saxon.parse() the UID is correctly transformed to
POWER_FAILURE.

Console output:

Code:

PRE-MAP:raw-value: [b02fb601b98a47ce8de32dbb157fb2a2]
POST-MAP:[b02fb601b98a47ce8de32dbb157fb2a2]
PRE-MAP:raw-value: [b02fb601b98a47ce8de32dbb157fb2a2]
POST-MAP:[POWER_FAILURE]
