I'd appreciate any comment that would help me improve this solution.
Not sure if this would help improve it, but it hopefully explains the
following:
"It appears that Internet Explorer (prior to version 7) is seriously
ABBR-challenged as I could not find a way to get the nodeValue of
these elements. "
(Aside: elements have a nodeValue of "null" as per DOM Level 1:
<http://www.w3.org/TR/2000/WD-DOM-Level-1-20000929/level-one-
core.html#ID-1950641247>
I'm assuming you were referring to the nodeValue of the text node
children of the element.)
That's because IE<7 doesn't support ABBR, and instead parses the page
into a DOM containing a superfluous element with an invalid name. To
be precise, when dealing with
some text <abbr>ABC</abbr> some more text
rather than producing:
{text node}some text {end of text node}
{element name="ABBR"}
{text node}ABC{end of text node}
{end of element}
{text node} some more text{end of text node}
it will produce:
{text node}some text {end of text node}
{empty element name="ABBR"}
{text node}ABC{end of text node}
{empty element name="/ABBR"}
{text node} some more text{end of text node}
thus creating an empty element with the name "ABBR", another empty
element with name "/ABBR", and not wrapping the contents of ABBR but
instead leaving them at the same level as the empty elements.
Some more on this here:
<http://www.nickfitz.co.uk/2005/05/17/obscure-internet-explorer-
bugs-1-of-who-knows/>
(Although I still haven't produced the follow-up I mention in the
last paragraph, IE behaves the same way with any unknown tag).
You might therefore be able to get it working for IE<7 by using
conditional comments to include a script file with an alternative
definition of the function that gets the value of the element's
children, which takes account of this and scans the following-
siblings of the ABBR element looking for the /ABBR element.
Also, Dean Edwards (Whom God Preserve) found a way of using
namespaces to force IE to behave:
