Hi all,
Sorry for silly question but I think that it might be a nice feature
to webkit.
The following code works in Mozilla Firefox 3.5, but it does not work
in webkit-based browsers:
var parser = new DOMParser();
var str = "<p>This is a test</p>";
var doc = parser.parseFromString(str, "text/xml");
document.body.appendChild(doc.documentElement.firstChild);
If you change the last step to this, it will work in WebKit-based
browsers:
document
.body.appendChild(document.importNode(doc.documentElement.firstChild));
The Gecko engine is more generous about allowing implicit cross-
document adoption. We allow it in only a few cases, and in theory it
is not supposed to be allowed at all (without the importNode call)
according to the DOM Core spec. That being said, if this is a compat
issue on real sites we can change to be more Gecko-like.
I found that specification to DOMParser does not guarantee that the
result of DOMParser's parseFromX methods can
be directly used in the original document.
Nevertheless I believe that it would be quite a useful feature, at
least it won't require JS code to create DOM-compliant content from
the parsed one.
May be I missed something and webkit offers a way of quick adaptation
of the parsed content to the original DOM tree?
Thanks in advance.
P.S.: even though Firefox provides such a feature, a style
specification in the following code will take no effect:
var parser = new DOMParser();
var str = "<p style='color: red;'>This is a test</p>";
var doc = parser.parseFromString(str, "text/xml");
document.body.appendChild(doc.documentElement.firstChild);
Probably because parsing with DOMParser parses as XML, thus you get a
<p> element that's not an HTML element (it is in the null namespace
instead of the HTML namespace). To get an HTML p element you need to
either do this:
var str = "<p xmlns='http://www.w3.org/1999/xhtml/'
style='color: red;'>This is a test</p>";
or just use innerHTML or createContextualFragment to directly insert
HTML text into a document.

Maciej
