XML String Length

danindublin

Hi Guys,

Using the following code to parse some XML but it wont return anthing thats longer than a line of txt. The xml is created from html textareas on a php page. All works fine until there is a new line in the text. Anyone any ideas

$itemtitle = preg_match_all("/<".$xl[$count2].">(.*?)<\/".$xl[$count2].">/", $data, $match);
$replace = array('<![CDATA]>'=>'');
$_SESSION[$names[$count2]]= strtr($match[1][0],$replace);

Okay, firstly if you are doing to work with XML don't try regular expression matching to get what you want. It's slow and there are plenty of easier ways.

I don't know how $data looks but if it is for example
<data>
<title></title>
<name></name>
</data>

You can access it's parts much more simply with

$simpleData = simplexml_load_string($data);
$title = $simpleData->title
$name = $simpleData->name


Check out http://ie.php.net/simplexml for more details, but you'll find it much much easier for working with XML than what you have. And you won't have problems with it only handling a single line.

Thanks CrimsonGhost,

The only reason I've been using this more complicated version is because I'm working off a server that only has php version 4.4 whereas simpleXML needs v5+.

Ahh, right. You might tell them PHP5 when production over 3 years ago and support for php4 ends at the end of the year. (Ref: http://www.php.net/#2007-07-13-1).

As a possible solution, a bit hacky mind, could you do a preg_replace before your match and replace all "\n" with "", should give you the whole thing as a single line. It may run a little slower but should give you a result quick enough.

In perl . doesn't match end of lines. So either add an 's' modifier after the final / or replace end of lines with a space.
