TYPO3 Core

Hello there,

I recently ran into a problem with GeneralUtility::xml2tree (formerly known as t3lib_div::xml2tree) where I tried to parse a file that had a tag that was empty. Now because of the strict behavior of xml2tree, the file failed to parse.

Indeed the xml parser is set to not skip white (empty) entries which leeds to an error and then stops parsing.

It would be nice to have the possibility to either modify the behavior of xml2tree globally or to have it to be configurable by parameters. Both could be implemented without risking backwards incompatibility.

Personally I'm a fan of the additional function parameters which I'd implement like this:

...
static public function xml2tree($string, $depth = 999, $caseFolding = 0, $skipWhite = 0) {
    $parser = xml_parser_create();
    $vals = array();
    $index = array();
    xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, $caseFolding);
    xml_parser_set_option($parser, XML_OPTION_SKIP_WHITE, $skipWhite);
...

Thank you for you're feedback!

Best Regards
Tizian
