:how can i use regular expression in c and how can i strip html tags
:from one string with c.
html cannot be properly analyzed as regular expressions. html allows
nested entities (e.g., nested tables), but regular expressions cannot
be used to match beginning and endpoints -- regular expressions are
not powerful enough to remember how many of something have been seen.
If you do not have a firm requirement to write in C, then I suggest
that you consider using perl with the LWP module. All of the code
for extracting tags properly has already been implimented in perl.
XML and SGML parsing modules are also readily available.
If you -do- have a firm requirement to write in C, then you could
look at the perl LWP module for algorithm ideas. Or you could
generate libperl and call upon that from your C program to do the work
for you. perl itself is written in C, and can be called as library
functions relatively easily.
