Checking heading structure

N

Neeraj

Does anyone have a clever algorithm for checking if the page has
proper heading structure. By proper structure i mean that Headings
should be properly nested. Heading 1 being main title, and the rest
flow in correct order.

Any help will be appreciated.

Thanks,
Neeraj

What kind of heading are you talking about ? Are you trying to
validate an HTML document ? Please elaborate on what you're trying to
do.


Kind regards,

Are you referring to the copy editor's view that

1) There must never be a single Hx.

2) Hx can only be followed by Hx or H(x-1) or a higher Hx.

Or are you referring to the order of things in the <head> section?

Here, mtr is 32-bit MiniTrue, see signature; but other RegExp tools
might serve. This assumes that all headings are written <H#> without,
for example, any style or class; and that <H#> does not otherwise occur.

There must always be an <H1> first.

AFAICS, the only other error is to have a heading followed by another
which is higher in number by more than 1.

Example :
MSDOS prompt mtr -o -x+ european.htm ".*<H(\d)>.*\n" = \1
result 12334354423444444334442223434555554455542334244233

shows just the numbers of the headings of that page.

The errors are having in it any of 13 14 15 16 24 25 26 35 36 46 ; the
rest is up to you.

One should be able to write a JavaScript function to do the same or
similar to document.body.innerHTML of the page that it is executed in,
and to provide it from an include file.

Define that.

ACK.

Hardly, those are falsely called headers by some people, but not headings.

Hi,
Sorry for not providing the complete information. Yes, I am trying to
validate a web page.
I wanted to check whether the heading tags i.e H1,H2,H3...H6 are
properly structured meaning that they should be in hierarchy.

Headings should be properly nested following the heading levels
represented by the numerical values of the heading elements.

* h2 should be used as sub-heading after a h1
* h3 should be used as sub-heading after a h2
* h4 should be used as sub-heading after a h3
* h5 should be used as sub-heading after a h4
* h6 should be used as sub-heading after a h5


Thanks,
Neeraj

NACK.

ACK, must be H(x *+* 1) and *lower* Hx instead (probably the confusion draws
from the fact that a higher-level heading has lower an x), and "followed by"
must disregard all non-Hx elements to make sense.

Totally agree. I need a simple help, i am unable to find out the way
to do this out through javascript. Any help regarding this will be of
great use.

It's all very well saying that you want to do it with JavaScript; but do
you want to have JavaScript called in a Web page to check that Web page
(which poses a burden on any readers that you may have), or do you want
to have JavaScript called in a Web page to check other Web pages on the
same server or on another server, or do you want to use JavaScript run
in WSH to check draft Web pages on your editing system? Whoever sets
your work should be more explicit.

Consider :

var S = document.body.innerHTML, T = [], J = -1, L, X=0, Y
while (-1 < (J = S.indexOf("<H", J+1)))
T.push([+S.substr(J+2, 1), S.substr(J, 30)])
for (J=0, L=T.length ; J<L ; J++) {
Y = T[J][0]
if (Y>X+1) alert(X+" "+Y+" "+T[J][1])
X = Y }

Hi,
Thanks for your response. I want to have JavaScript which would check
all the web pages passed to it. If you have a javascript for such
thing then can you share it with me.

Thanks,
Neeraj

When you show convincing signs of having understood the regularly-posted
newsgroup FAQ, and when you have learned to give sufficient detail when
