getting coordinates of a text node (in Firefox)

[wolfgang.schwarz]

hi,

is there a way of getting the position and size of a text node in
Firefox without altering the DOM? For example, suppose I have a
document fragment like this:

<div>
textnode1
<img>
textnode2 textnode3
</div>

I can get the div's coordinates, but that doesn't help me much if I
want to know the position (and ideally also the size) of textnode2. I
could wrap the text node into a new <spanelement, but that often
alters the look of the page.

I need this for a xulrunner application, so it's fine if it only works
in (some version of) Firefox/Mozilla.

Thanks,
wo.

Why would you have two text nodes after the img element? Are you
constructing the DOM with script and appending two text nodes? Otherwise
there is only one text node after the img, even if there are several
words in the text contents.

I don't know of any properties exposes in Mozilla's DOM on text nodes
that would yield a position. You might want to ask in mozilla.dev.tech.dom.

I actually need the coordinates of every line of text on the page,
that's why I split the text nodes at linebreaks.
