Problem:
user extracted the xml text from a PPT due to the fact that PPT file weighs too much (over 150MB) and is trying to process it via XML filter in Wordbee.
Solution:
working this way with big PPT files is not a good practice since configuration for processing such XMLs can change between office versions, and even with the same version it's difficult to say which nodes need translation (it depends on the content of the structure).
Moreover, all the data of a ppt file are not stored in one xml file, but in multiple xml files with relations.
It should be easier to split the original document into multiple pptx files and then treat them in Wordbee.
Additionally one might like to have a look here to understand the xml structure better:
