Don't use wrong tech lingo. I wouldn't call any of those a glob.

I agree, it can be tricky for people who are not used to
Unix-style/csh-style globbing.

I must be missing something. What do those variable definition have to do
with glob()?

I think what the author of the note may be asking about is the
difference between 'my', 'local' and no explicit declaration which
effects scope and not globs. I believe, but am also sure someone else
will procide a more precise definition, is that 'my' limits the scope to
the block in which it's asserted, 'local' carries the scope into other
blocks that are entersd from the one in which it's asserted and if there
is no explicit declaration, the variable is global. sort of...

What he is talking about are type globs, to be confused with file globs.
File globs are used with the function glob().
Type globs are used to alias variables. Perl 4 did not have references,
so you had to use type globs instead. In Perl 5, use references except
for file handles, then 'use FileHandle;'
Type globs, like formats, left over from Perl 4 and people rarely use
them since there are better ways to do things.

It seems to me that perldoc would. Perhaps you can suggest a better term?

Subject: Parsing HTML using TreeBuilder - how to get the "next" tag?
Message-Id: <wWaBRTSjNKrCFwtS@horrocks.plus.com>
I have a large (6Mb) HTML file that has been generated by a software
application's "document" function which I am trying to parse using
HTML::TreeBuilder. It consists of lots of lines in the form:
<p> Text text text text text
<p> Text text text text text
...
<p> Text text text text text
<h1>Section Heading</h1>
<p> Blah blah blah blah
<p> Blah blah blah blah
<p> Blah blah blah blah
...
I can use $tree->look_down() to find the h1 heading but then, how do I
get the next line? All the examples assume that the thing you want is a
*child* of the heading, not the *next* tag.
This requirement seems to be so basic that I must be missing something
but I can't see what. Perl is ActiveState 5.8.6 on Win32.
Thanks in advance

Okay, found it (I think)
HTML::Element->right() looks to be what I'm after. Sorry for the noise.
