I'm trying to double line breaks in a user-entered field into XML. I've tried matching them with a simple regexp:
'<paragraph>' . preg_replace('/^^/m', "</paragraph>\n\n<paragraph>", $_POST['post']); . '</paragraph>'This does seem to be matching the paragraphs, but it goes over the top. For example,
hello

worldGives
<paragraph></paragraph>

<paragraph>hello

</paragraph>

<paragraph>

</paragraph>

<paragraph>world</paragraph>Any insight/solutions?

All right, no-one seems to have a clue. Perhaps relevant: I'm using Windows which uses [lf][cr] to mark new lines, compared to unix where simply [lf] is used. Could this be why?

thats exactly the reason

run an str replace to delete all occurances of \r

as for matching double line breaks why not use "'\n\n's" ? ( i use a single quote as a delimiter)

Finally got it to work! Thanks! Here's my final code:
$postnew = str_replace("\r", '', $_POST['post']);
$postnew = str_replace("\n\n", "[ot]/paragraph[ct]\n\n[ot]paragraph[ct]", $postnew);

Just a comment,

Thanks for posting your solution. All to often I notice people get things to work and simply post something like "I got it, thanks". Although this is great, It really annoys me when I search this forum and can't find the answer because it wasn't added at the end of the thread.

I know I too am guilty, but I just wanted to point it out and say thanks me' :thumbsup:

am i correct to assume that you later change all occurances of [ot] and [ct] into < and > respectively?
