Reading part of contents from other page via XMLHttpRequest

[JP]

Hello,

I am trying to figure out how can I read particular content of the page
after I have requested page into XMLHttpRequest object.
Is there a way to parse somehow responseText? In pseudo code I want to
do something like this.

var myHeader = myXMLHttpRequest.document.getElementById("Header");

If you load an XML document then you have
myXMLHttpRequest.responseXML
as a document and you can use the W3C Core DOM on that. getElementById
in XML documents works only if the document type definition defines
attributes of type ID.

Thanks for reply.
Seems like IFRAME is the only solution. I was quite suprise that I
cannot parse outputting HTML.
It would be nice if there would be responseHTML which would be document
object of the xmlHttprequest.

Provided your HTML element has an `id' attribute of type ID and
value "Header", you could do something along

var m = myXMLHttpRequest.responseText.match(
/<[^>]+\s+id\s*=(["']|\s*)Header(["'])(\s+[^>])*>/i);

However, outputting X(HT)ML as application/(xhtml+)xml and using
a parser object or responseXML instead is the sane approach.
