address LINK object in the HEAD section

V

VK

Having HEAD section like that:

<head>

<title>Foo</title>
<meta http-equiv="Content-Type"
content="text/html; charset=iso-8859-1">

<link
title="linkObject"
rel="Alternate Appendix"
type="text/plain"
href="data.txt"
charset="iso-8859-1"
hreflang="en-US">

</head>

what would be the most realible way to get "linkObject" reference?

var roof = document.getElementsByTagName('HEAD')[0];
// ?

Replacing `title=' with `id=' and using Document::getElementById().

Are ID's formally allowed for LINK? Or for other elements in the
non-rendering section (HEAD) I did not find this attribute listed
neither in W3C nor in MSDN. From the other side TITLE is required by
W3C for alternate content links.

Not to say I technically care too much but for some reasons I want to
have this LINK usage free of any "hacking model" accusations. Unusual -
yes, but fully standard compliant.

You must have a different "W3C" and "MSDN" than I have ;-)

The `id' attribute is allowed for "All elements but BASE,
HEAD, HTML, META, SCRIPT, STYLE, TITLE".
See <URL:http://www.w3.org/TR/html4/index/attributes.html>

,-<URL:http://msdn.microsoft.com/workshop/author/dhtml/reference/properties/id.asp>
|
| Applies To
| [...] LABEL, LEGEND, LI, LINK, LISTING, [...]
^^^^
The (X)HTML DTDs clearly state the `link' element has the `id' attribute:

<URL:http://www.w3.org/TR/REC-html32#link>

<http://www.w3.org/TR/html4/struct/links.html#edef-LINK>
(note the `%attrs;' entity reference and follow the links
<URL:http://www.w3.org/TR/html4/sgml/dtd.html#attrs>
<URL:http://www.w3.org/TR/html4/sgml/dtd.html#coreattrs>)

<URL:https://www.cs.tcd.ie/15445/15445.html#DTD>
(search for "ATTLIST link")

<URL:http://www.w3.org/TR/xhtml1/dtds.html#dtdentry_xhtml1-strict.dtd_link>
(search for "ATTLIST link", note the `%attrs;' entity reference and follow
the links)

The `title' attribute, however, should provide for a short description of
the element.

From the other side TITLE is required by W3C for alternate content links.

How do you got that idea?

But you should, for your own sake and that of users of your content.

Accessing the `id' attribute value is sufficiently un"hack"ish :)

var tem=A;
if(tem.getAttribute(attrib)){
if(str) tem.getAttribute(attrib)==str) O.push(tem);
else O.push(tem);

return O;
}
// In your case you can call: getElementsByAttribute('link','title',str)
(str is whatever you want to match)
