Re^3: perlmonks downloadable code blocks

PM does a bit more than that — it escapes "<", ">" and "&", at least — but that's the idea.

By the way, I'd add the "g" modifier to your s///. There's no reason to search from the start of the string every pass.

Well if I use the global "/g" modifier it will replace all of my tags at once and $i will never be incremented.	[reply]

True, unless you get rid of the `while` entirely. The first paragraph of `s///` documentation reads: (Emphasis mine) Searches a string for a pattern, and if found, replaces that pattern with the replacement text and returns the number of substitutions made. So you get `my $post_body = ...from db...; my $match = s/.../.../ig;` [download] By the way, I don't think `$match` should be singular. `$matches` is better but not nearly as descriptive as something like `$num_blks`.
