inserting text into HTML

I have a big list of HTML files, which need to be updated with a
common text.


<script language=JavaScript
src="./highlight.js"></script>

I need to add the above line in each of the html files, before the
text "<\head>". All the HTML files have this text and I think some
kind of search on this string and either replacing "</head>" with the
text above and appending "<\headto it, might be one way to do it or
just find the <\headpart and insert the text before that.



On similar lines, the text below goes towards the end. The problem is
similar to the above one and I think all that needs to be done, is
read the text below from a file, do a similar search for some text
below which this insert part should go and put it there.


<p><script type="text/javascript">var mailSubject = 'Hardware
Overview';
var mailBody = 'Your Technical Support Team hopes this topic will
be helpful: ' + location.href;
var mailDisplay = 'Click here to email this topic.';
document.write(
'<a href="mailto:YourName@YourAddress.com'
+ '?subject=' + escape(mailSubject)
+ '&body=' + escape(mailBody)
+ '">' + mailDisplay + '</a>'
);</script></p>

<script type="text/javascript"
language=JavaScript1.2><!--
beginSearch ();
//--></script>


Any ideas would be helpful. I do not know much about perl and hence
the more the better.
Thanks a lot

Scripsit Slain:
Oh, you mean </head>. Are you sure? Well, then you could write a Perl
few-liner to do the job, or ask someone to write it for you. You would still
need to learn how to run a Perl program _on the server_. The program could
be something like the following (untested):

undef $/;
while(<*.html>) {
$filename = $_;
open(FILE,"<$filename")
|| die "Can't open file \"$filename\":\n $!";
$stuff = <FILE>;
$stuff =~ s?</head>?<script language=JavaScript
src="./highlight.js"></script></head>?;
close(FILE);
open(FILE,">$filename")
|| die "Can't open file \"$filename\" for writing:\n $!";
print FILE $stuff;
close(FILE);
}

Of course, this isn't real about authoring in HTML. The c.i.w.a.tools group
would have been more suitable. And of course you might find an editor with a
built-in multi-file string replace feature that could be used for the job.
Well, of course it would be similar, with similar solutions, though
detecting the end is non-trivial. But...
This sounds like a _very_ clueless method of giving some users some poor way
of contacting you, instead of simply telling all users your email address.
So if you do something _so_ stupid, at least do it via some server-side
include feature, so that when you come to your senses, you won't have to fix
a zillion files again but can simply fix the included file.

It's </head>.
Just use an advanced text editor to do that. It's simple to do.

Free software (libre/open-source) text editors:

You're overreaching here in my opinion. And your code has problems.
First, you must escape the ampersand with &amp;
Second, you are adding a closing </ptag when there is not a start <p>.
Third, you'll need to escape the closing tags inside the document.write
block:

Common HTML Validation Problems
Writing HTML in a SCRIPT element
http://www.htmlhelp.com/tools/valida...html.en#script

HTML 4, Section 18.2.4 Dynamic modification of documents
http://www.w3.org/TR/html4/interact/....html#h-18.2.4

HTML 4, Appendix B.3.2 Specifying non-HTML data, Element Content
http://www.w3.org/TR/html4/appendix/...html#h-B.3.2.1
"When script or style data is the content of an element (SCRIPT and
STYLE), the data begins immediately after the element start tag and ends
at the first ETAGO ("</") delimiter followed by a name start character
([a-zA-Z]); note that this may not be the element's end tag. Authors
should therefore escape "</" within the content."



As mentioned already, language attribute is deprecated.

Don't use HTML comments as they are unneeded, unnecessary and
potentially harmful.
