[Tellico-users] xslt question about overwrtiting values

[Xavier Brochard]

Hi Robby

Could you help me ?

>From Amazon XML data source, I would like to retrieve ItemDimensions or 
PackageDimensions, which one it doesn't matter. Sometimes only one of the twos 
is available.
Instead of testing values I would like to overwrite, but I'm not sure about 
that : if a value is empty, will it overwrite the first value retrieved ?

Sample cases :
---------------------
First:
ItemDimensions:Width  123
ItemDimensions:Height 456
=> ItemDimensions values are affected to fields
PackageDimensions:Width 124
PackageDimensions:Height 457
=> then PackageDimensions values overwrite field's content

Second:
ItemDimensions:Width  123
ItemDimensions:Height 456
=> ItemDimensions values are affected to fields
PackageDimensions:Width (empty)
PackageDimensions:Height (empty)
=> then PackageDimensions values doesn't overwrite field's content

I know I could test myself, but as I'm not "fluent" in XSLT, it would takes 
time to found an error.

thanks in advance
