Given an HTML file which looks like this:
--------- begin snippet --------- <HTML
<HEAD <TITLE We've Lied to You…</TITLE <META
NAME="GENERATOR" CONTENT="Modular DocBook HTML Stylesheet Version 1.79"><LINK REL="HOME" TITLE="Maximum RPM" HREF="index.html"><LINK REL="UP" TITLE="Using RPM to Verify Installed Packages" HREF="ch-rpm-verify.html"><LINK ... --------- end snippet ---------
I'm coding some perl to make it look something like this:
--------- begin snippet --------- <html> <head> <title>We've Lied to You…</title>
<meta name="generator" content="Modular DocBook HTML Stylesheet Version 1.79">
<link rel="HOME" title="Maximum RPM" href="index.html">
<line rel="UP" title="Using RPM to Verify Installed Packages" href="ch-rpm-verify.html">
<link .... --------- end snippet ---------
I've hit a wall trying to remove all the newlines. I've tried it several ways... here's just one:
--------- begin snippet --------- while (<$in>) { s/<(\w*\W)/<\L$1/g; # Downcase XXX in "<XXX". s/</(\w*\W)/</\L$1/g; # Downcase XXX in "</XXX". if(/^>/) # if this line starts with '>' { # then $curr = tell $in; # Note current file position, seek $in, $prev, 0; # go back to previous line, chomp; # remove its trailing newline char, seek $in, $curr, 0; # and reset position to current line. } else { $curr = tell $in; # Note current file position, seek $in, $prev, 0; # go back to previous line s/\n/ /; # Append a space, chop; # and then chomp. seek $in, $curr, 0; # and reset position to current line. } print; print $out; $prev = tell $in; # Location of previous line. } --------- end snippet ---------
When I cat the output file, it looks like this:
--------- begin snippet --------- GLOB(0x9fd587c)<htmlGLOB(0x9fd587c)><headGLOB(0x9fd587c)><titleGLOB(0x9fd587c)>We've Lied to You…</titleGLOB(0x9fd587c)><metaGLOB(0x9fd587c)NAME="GENERATOR"GLOB(0x9fd587c)CONTENT="Modular DocBook HTML Stylesheet Version 1.79"><linkGLOB(0x9fd587c)REL="HOME"GLOB(0x9fd587c)TITLE="Maximum RPM"GLOB(0x9fd587c)HREF="index.html"><linkGLOB(0x9fd587c)REL="UP"GLOB(0x9fd587c)TITLE="Using RPM to Verify Installed Packages"GLOB(0x9fd587c)HREF="ch-rpm-verify.html"><linkGLOB(0x9fd587c).... --------- end snippet ---------
The output I should say *is* all on one line, not line-wrapped the way you see it above. I have a hunch as to why there are the "GLOB(0x9fd587c)" thingies everywhere the newlines or spaces (' ') should be. If some expert here could explain them, that would be really good. More importantly though would be some instruction as to how to remove the newlines without creating all the GLOB(...) garbage. Might I have to rewrite the script so to open the file in binary mode... or what?
Maximum thanks for your assistance.
