Hi brethren, I have a problem coming to grips with writing changes to an HTML file via a filehandle. Hope the Abbey can cast light upon my coding darkness...what am I doing wrong?
#!/usr/bin/perl # write mods to HTML file.plx # Program will read in an html file, remove the img tag and rewrite HT +ML on E-drive. # 1. No need for file variable yet: open (INFILE, "<".$htmlFile) or di +e("Can't read source file!\n"); # 2. Alternative: m/<A\s+HREF=[^>]+>(.*?)<\/A>/ - Will not remove clo +sing tag though - why? # 3. Why is interpreter flipping-out over an 'undefined variable', whe +n # original regexp, m/<A\s+HREF=[^>]+>(.*?)<\/A>/, is known to work. + What am I missing? use warnings; use diagnostics; use strict; # Declare and initialise variables. my $pattern1 = '<IMG\s+(.*)>'; my $pattern2 = '<A\s+HREF\s*=[^>]+>'; my $pattern3 = '</A>'; my @htmlLines; my @htmlFile; # Open HTML test file and read into array. open INFILE, "E:/Documents and Settings/Richard Lamb/My Documents/HTML +/test1InDocCSS.html" or die "Sod! Can't open this file.\n"; @htmlLines = <INFILE>; close (INFILE); scrapImageTag(); scrapAnchorTag(); # Removes image tag elements in array sub scrapImageTag { foreach my $line (@htmlLines) { # replace <IMG ...> with nothing. $line =~ s/$pattern1//ig; # case insensitivity and global search +for pattern } } # Removes anchor tag elements in array sub scrapAnchorTag { foreach my $line (@htmlLines) { # replace <A HREF ...> with nothing. $line =~ s/$pattern2//ig; # case insensitivity and global search +for pattern $line =~ s/$pattern3//ig; # case insensitivity and global search +for pattern } } # Am I deleting the contents of the list with this? Not sure... open (OUTFILE, ">@htmlLines") or die("Can't rewrite the HTML file.\n") +; print OUTFILE "@htmlLines\n"; close (OUTFILE);
I'm trying to write the changed code back to the file on the hard-drive, by writing on a filehandle, so I can re-open the html document. I use a print operator? I have to come clean and say that the file writing's confusing the Hell out of me. Are file tests the answer, assign to a new list variable? Time to try. Here's the code I've written so far - the file won't open for writing (yet). Confusion!!! Rich
