I saw the line below in code for a DOM parser at this tutorial.
doc.getDocumentElement().normalize();
Why do we do this normalization ?
I read the docs but I could not understand a word.
Puts all Text nodes in the full depth of the sub-tree underneath this Node
Okay, then can someone show me (preferably with a picture) what this tree looks like ?
Can anyone explain me why normalization is needed?
What happens if we don’t normalize ?
