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.

Try putting in a hidden iframe:

<iframe id="myXMLHttpIframe" style="display:none;">
...
myXMLHttpIframe.document.body.innerHTML =
myXMLHttpRequest..responseText;
myHeader = myXMLHttpIframe.document.body.getElementById("Head er");

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.
