Edit report at https://bugs.php.net/bug.php?id=74201&edit=1 ID: 74201 Updated by: requinix@php.net Reported by: dac514 at hotmail dot com Summary: Strange SimpleXMLIterator Behaviour -Status: Open +Status: Wont fix Type: Bug Package: SimpleXML related Operating System: CentOS -PHP Version: Irrelevant +PHP Version: 5.4.35 Block user comment: N Private report: N New Comment: Seems it was fixed in 5.5.27, which came with the fix for https://bugs.php.net/bug.php?id=66084 https://github.com/php/php-src/commit/5683b6fa3962f483a407ca17d49397b203ed4145 and other similar bugs that were caused by whitespace issues. The change was fairly simple (within sxe_get_prop_hash) so you should be able to apply that to the 5.4 sources and build a custom patched version for yourself.

I understand that these versions are not supported but for this particular project this is the best we can do. The weird thing is that this code works in 5.3, 5.5, 5.6, 7.0 ... But not 5.4.35 on CentOS. Running the attached test script on that particular version will echo "> YOU HAVE FAILED... " I'm looking for some help, duplicate bugs that explain what is going on, or workarounds. Thank you for your time.
