245092 - text in element in XML document is split up into chunks of 4096 characters resulting in a DOM document that is not normalized

Status: RESOLVED DUPLICATE of bug 194231

(Core :: DOM: Core & HTML, defect)

Description

[Martin Honnen]

This bug is filed as a followup to the newsgroup thread
 
http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&threadm=c96qa9%245541%40ripley.netscape.com&rnum=3&prev=/groups%3Fq%3Dgroup:*mozilla*dom*%26hl%3Den%26lr%3D%26ie%3DUTF-8%26scoring%3Dd
where Boris mentions that the Mozilla parser breaks up text nodes into chunks of
4096 characters. However the DOM Level 2 Core specification 
  http://www.w3.org/TR/DOM-Level-2-Core/core.html#ID-1312295772
clearly says that
  "When a document is first made available via the DOM, there is only one Text
node for each block of text."
so the Mozilla behaviour to create several adjacent text nodes of 4096 or less
characters is a bug.
I will attach a test case that demonstrates the bug by counting the child nodes
of an element node first after the document has been loaded and parsed and then
again after the normalize function has been called. 
I have tested with Netscape 7.1 (Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US;
rv:1.4) Gecko/20030624 Netscape/7.1 (ax)), Mozilla 1.8a (Mozilla/5.0 (Windows;
U; Windows NT 5.1; en-US; rv:1.8a) Gecko/20040430) and Firefox 0.8, all exhibit
the bug.

Attachment: XML document needed for test case (has one element node with text content of more than 4096 characters)

Comment 2

[Martin Honnen]

Attachment: test case (loads XML document and counts number of child nodes of root element, should be one child node but there are three)
