Duplicate HashEntry

Hi,
I'm trying to write a Script that must have the ability
to duplicate a line in a HTML-Document.
Is is possible anyway?
e. G.

foreach $zeile (@dateiinhalt)
{
if ($zeile =~ m/Platzhalter1\.jpg/o)
{
# duplicate that line before substitution and s///i
# 1 line afterwards
$zeile =~ s/Platzhalter1\.jpg/$Bild1Name/i;
}
else
{
if ($zeile =~ m/Platzhalter2\.jpg/o)
{
$zeile =~ s/Platzhalter2\.jpg/$Bild2Name/i;
}
}
print VORLAGE ("$zeile");
}
close (VORLAGE);

Please excuse the German names, but since i am german it is easier for
me to understand that lang.

Not sure what your query has to do with hashes...

Yes, of course it is, and the question is asked frequently:

perldoc -q "insert a line"

To prevent that the loop gets

when you add lines/elements, you
may want to loop through the array backwards.

However, since it's an HTML document, I don't understand why there is a
need to add lines. Can't you add whatever it is you want to add on
existing lines?

What's easier for *you* to understand is irrelevant if you want that
others shall read your post. When asking for help, you should make it
easy for others to help you.

Now, personally I'm not bothered by those German var names, even if
Swedish names would of course have been much more convenient to me. ;-)

I take that file as a Template for an indexfile (index.html) and i
want to add lines usings Perl's Pattern matching functions.

e. g.:
<html>
<body>
<ul>
<li>< a href ="Placeholder">Placeholder</a></li> # duplicate this line
# add another <li>-Line (with correct links!)
</ul>
</body>
</html>
>

oohh, great. After thinking another two Hours, i think i have a
solution.
(just Pattern-Match on the first </li> and write a correct line AFTER
it)

I may be incorrect, but since they all are var-names they should be
clear. Okay they are not hashes. Sorry for that.

What I mean is that

<ul>
<li>something</li>
<li>somethingelse</li>
</ul>

is rendered exactly the same as

<ul>
<li>something</li><li>somethingelse</li>
</ul>

That's why I don't understand why you need to bother with adding extra
lines to the file.

Hi,
I think i give an exact example:

index.html (before):

<html>
<body>
<ul>
<li>< a href=(link_to_somedata>somedata</a></li>
</ul>
</body>
</html>

and after program execution:

<html>
<body
<ul>
<li>< a href=link_to_somedata>somedata</a></li>
<li>< a href=link_to_some_otherdata>someotherdata</a></li> # <- This
</li>
</ul>
</body>
</html>

I want to add the second line into the list of links !!!!
But not simply add one line but a few by program.
Everytime a user creates a subdir i want this subdir to be added to
this linklist. I don't want to format these lines to look better.

Okay, you want additional lines. Fine. HTML is off topic here anyway.

You said that you have a solution. If not, you did notice my pointer to
the FAQ, didn't you?
