Bug 17765 – Empty CDATA section is not added to DOM when parsing

• Component: DOM
• Status: RESOLVED CONFIGURATION CHANGED

[benoit]

it's not possible to retrieve an empty cdata section (<![CDATA[]]>) with the firstChild property : null is return.

Ex: <testWebkit><![CDATA[]]></testWebkit>

with node = <testWebkit>
var child = node.firstChild;

on safari child is null
on ie 6 and ff 2 child is a node type 4 (CDATA_SECTION_NODE) with an empty content

tested on safari 3.0.4 and nightly build 30790

html test with domparser

html test. Use domparser but the pb is the same with xmlhhtprequest.
This test does not work on ie (replace domparser with ActiveXObject)

Not just firstChild, seems to be anywhere in a particular container.

Confirmed with r30984.

With r34104 i got the right resut: "first.child type = 4"

[Alexey Proskuryakov]

I'm still getting "first child is null" on the attached test case (also with 34104, local release build).

I'm still getting "first child is null"  with 35844

Seems to be working in Safari 5.1 on Lion. We'll need to land this test to avoid regressions.

Mass moving XML DOM bugs to the "DOM" Component.

I am unable to reproduce this bug using attached test case in Safari 15.6 on macOS 12.5 and it shows "first child type = 4" and matches with all other browsers (Chrome Canary 106 and Firefox Nightly 105). I think this can be marked as "RESOLVED CONFIGURATION CHANGED". Thanks!

From Comment 8 - it seems we need to land this test case to avoid future regressions but I am not sure whether we have WPT coverage or not. Please do accordingly. Thanks!

Yup, config changed.
