Now I would like to leave some line breaks.
For example, if $html has something like this:
"<textarea> default text\n with line \nbreaks </textarea>"
I would like to leave all the linebreaks between the <textarea> tags.
Does any one know of a script, or a regular expression that can do this ?
Re: selective replacements
i used this method :
1.replace the '\n' i want to keep with a strange char such as x23 one
thus,the regex is easy to access
2.after replaced all '\n's should be kept, use '\r' to take place of
the '\n' left is really what you want to replace
3.turn our strange char(x23) back to '\n'
your should make several easy reg expressions,
but not a big big one.
