XMLparse empty tag

[Enricoys]

Unfortunately I hoped that in the new version 14.4.01 an annoying problem with XMLparse would have been solved. However, I still see a system error occurring as soon as XMLparse is used for an empty tag. Now I have to make a relatively complex check before I can use XMLparse. I would guess that it is just a minor modification in XMLparse to return a empty field when the tag is empty in the XML file. Could you please modify XMLparse behaviour in the next version.

Sorry we missed that. I've made sure it is on bug tracker and will give this priority to investigate and fix.

This is how i like to use xmlparse:

Note: title for <book category="CHILDREN"> is empty and will return null with no error warning.

Code: Select all

Let>IGNOREERRORS=1
LabelToVar>XML,sXML
XMLParse>sXML,/bookstore/book,val,numBooks
Let>k=0
Repeat>k
  Let>k=k+1
  XMLParse>sXML,/bookstore/book[%k%]/title/text(),val,len
  MessageModal>val
  Let>val=
Until>k=numBooks
 
Let>IGNOREERRORS=0
