[pm-h] perl application: I'm in over my head

[Russell L. Harris]

I have a small programming problem which is a bit over my head.  

The problem involves web pages which I am generating with hyperlatex.
It has just been brought to my attention that I need to add
"description" and "keywords" meta tags to my web site; but I have not
been able to do so directly with hyperlatex.  I am able to use
hyperlatex to create the appropriate meta tags for each HTML file, but
the tags are created in the body of the file, rather than in the head;
thus, my need is to relocate the tags.  

It seems to me that the following is a reasonable approach:

TASK: 

    When creating HTML files from a LaTeX source file, the "\xml{tag}"
    command of hyperlatex creates a meta tag in the body of the file.
    However, the the "description" and "keywords" meta tags belong in
    the head of the file, and there appears to be no way (short of
    hacking hyperlatex) to force hyperlatex to write a meta tag to the
    head of the file.

    Consequently, once the HTML file has been created, it is necessary
    to move the "description" and "keywords" meta tags from the body
    to the head.  

    A Perl routine invoked by a "make" file appears to be a good way
    to accomplish this task.

PROCEDURE:

For a fixed list of HTML files with assorted names:

    name1.html
    name2.html
    anothername1.html
    anothername2.html

and a variable list of HTML files which are systematically-named:

    TG_1.html
    TG_2.html
    TG_3.html
    ...
    TG_73.html
    TG_74.html
    ...

(1) Search for the tag: 

    <meta name="description" ... >

(2) If the tag is found, move the tag from the body of the HTML file
to the head of the HTML file, inserting it immediately following the
line of the title tag: 

    <title> ... </title>

(3) Search for the tag: 

    <meta name="keywords" ... >

(4) If the tag is found, move the tag from the body of the HTML file
to the head of the HTML file, inserting it immediately following the
line of the title tag:

    <title> ... </title>

(5) Proceed to the next file.

(6) Once all files in the two lists have been processed, exit.
