Description:
------------
A couple of weeks ago, we upgraded php to 5.3.19. Eversince the following bug 
appears: When I try to get the regex out of a XML file, he only gives the last 
piece as result.

<?xml version="1.0" encoding="utf-8" ?> <simplexml> <regex><![CDATA[/(^[a-zA-Z0-
9._-]+@[a-zA-Z0-9-]+.[a-zA-Z.]{2,5}\$)|^\$/i]]></regex> </simplexml>

The result is ']{2,5}\$)|^\$/i':

> FileHandler_Xml Object
(
    [_filename:protected] => 
    [_parser:protected] => 
    [_children:protected] => Array
        (
            [regex] => FileHandler_Xml_Element Object
                (
                    [_cdata:protected] => ]{2,5}\$)|^\$/i
                    [_attributes:protected] => 
                    [_children:protected] => 
                )
        )
    [obj] => 
)
I use 'XML Parser' to parse the XML to the object above.

I hope somebody can help me out with this problem?

With kind regards,

Pim

Test script:
---------------
public function addXml($xml){

               $this->_parserMemory = array();

        $parser = xml_parser_create( 'UTF-8' );

        

        xml_set_object($parser, $this);

        xml_parser_set_option($parser, XML_OPTION_SKIP_WHITE, 1);

        xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, 0);

        xml_set_element_handler($parser, "_xmlTagOpen", "_xmlTagClose");

        xml_set_character_data_handler($parser, "_xmlCdata");

    

        if (!xml_parse($parser, $xml)) {

            $this->_children = array();

            $error_code = xml_get_error_code($parser);

            $error_string = xml_error_string($error_code);

            $current_line = xml_get_current_line_number($parser);

            $current_column = xml_get_current_column_number($parser);


        }

        

        unset($this->_parserMemory);

        xml_parser_free($parser);

}

protected function _xmlCdata($parser, $cdata) 

    {
               
        if ( trim($cdata) != '' && count($this->_parserMemory)>1 ) {

            $obj = $this->getCurrentObject();
            

            $obj->setValue($this->_xmlConvertValueFromString($cdata));
            
            

        }
        


    }

Expected result:
----------------
> FileHandler_Xml Object
(
    [_filename:protected] => 
    [_parser:protected] => 
    [_children:protected] => Array
        (
            [regex] => FileHandler_Xml_Element Object
                (
                    [_cdata:protected] => /(^[a-zA-Z0-9._-]+@[a-zA-Z0-9-]+.[a-
zA-Z.]{2,5}\$)|^\$/i
                    [_attributes:protected] => 
                    [_children:protected] => 
                )
        )
    [obj] => 
)

Actual result:
--------------
The result is ']{2,5}\$)|^\$/i':

> FileHandler_Xml Object
(
    [_filename:protected] => 
    [_parser:protected] => 
    [_children:protected] => Array
        (
            [regex] => FileHandler_Xml_Element Object
                (
                    [_cdata:protected] => ]{2,5}\$)|^\$/i
                    [_attributes:protected] => 
                    [_children:protected] => 
                )
        )
    [obj] => 
)

I can't reproduce this issue with a simplified test script, see
<https://3v4l.org/4dcOo>.

If this issue still persists for you, please provide a minimal,
but complete and self-contained test script, and further info
about your environment (particularly relevant appear to be PHP
version, the value of XML_SAX_IMPL, and if that's "libxml", the
value of LIBXML_VERSION).
