regexp question!

[rdrnnr]

hello,

I'm trying to use preg_split to split up a bunch of html tables into an array of strings, using the open table tags for the split. the prob im having is there are two kinds of tables.

how do i do a regexp with an OR-style syntax?

-- something like this, but this isnt working:

$tables = preg_split ("/<table width\=100\% cellpadding\=3 border\=0 cellspacing\=0 bgcolor\=\"#EFEFEF\"> | <table width\=100\% cellpadding\=3 border\=0 cellspacing\=0 bgcolor\=\"#EFEFEF\">/", $str);

-- notice the only diff is the bgcolor value if that makes any diff.

thanks!

I see no difference in the bgcolor value.

What's with all the extra \ characters before your =, <, > and %?

im kinda new at this

the \'s are to escape any chars that might be messing up the regexp. i might have some unnecessary ones in there.

all i'm trying to do is say:

take this chunk of html and cut it into an array of strings, using EITHER of the open table tags as described above.

I have since found a way around it by just doing this

$str = eregi_replace ( '<table width=100% cellpadding=3 border=0 cellspacing=0 bgcolor="#EFEFEF">', '[###SPLIT###]<table>' , $str);

$str = eregi_replace ( '<table width=100% cellpadding=3 border=0 cellspacing=0 bgcolor="#FFFFFF">', '[###SPLIT###]<table>' , $str);

and then doing a single regexp like this:

$tables = preg_split ("/[###SPLIT###]/", $str);

... which is probably quicker since regexps (so ive heard) take more cpu than string replaces.

... but i'd still like to know how to do an OR style regexp!

thanks,

If the bgcolor is the only bit that's different, then...

/<table width=100% cellpadding=3 border=0 cellspacing=0 bgcolor="#(FFFFFF|EFEFEF)">/

is enough (escape the " if that's what you use around the string).

Suggest you use the PRCE functions though, faster.
