regX reformat of weather report!

Anon

hi, i just found out i need to rework my regX because the wx report format changesd and was hoping for some quick help (help!).

http://www.uac.pdx.edu/source.php?file=/avalanche.php

$rf = eregi_replace ("(*{8,})\n", " \1 ", $rf);
$rf = eregi_replace ("\n{2}([a-zA-Z0-9]{2})", "\n\n\1", $rf);
$rf = eregi_replace ("\n{1}^|\n", "\n \1", $rf);
$rf = eregi_replace ("[[:space:]]{5,}", "\n <IMG src=\"/images/spacer.gif\" width=\"50\" height=\"1\">", $sections[2]);

the idea is \n\n gets replaced with and a single \n with . any suggestions on keeping the second from being greedy?

thanks for your help on this URGENT! matter.

Yes:

$rf = eregi_replace("\n\n", "\n\n", $rf);
$rf = eregi_replace("([^{\n])\n([^\n])",} "\1 \n\2", $rf);

Might fail if \n is the first or the last char. This can be easily solved with (^{|[^\n])} and ($|[^\n]), but I wouldn't complicate if not necessary.
