If you didn't say "using regex" this is how I'd do it (untested, forgive typos and such..ripped from some code I actively use and stripped down):
<?PHP
$_XML_RESPONSE_PARSER = xml_parser_create();
xml_set_element_handler($_XML_RESPONSE_PARSER, 'xml_response_open_element_function', 'xml_response_close_element_function');
xml_set_character_data_handler($_XML_RESPONSE_PARSER, 'xml_response_handle_character_data');
xml_parse($_XML_RESPONSE_PARSER, $_XML_RESPONSE, strlen($_XML_RESPONSE));
xml_parser_free($_XML_RESPONSE_PARSER);
~
$FoundStatusTag = false;
~
function xml_response_open_element_function($p, $element, $attributes) {
global $FoundStatusTag;
~~
if (strtoupper($element) == "STATUS") $FoundStatusTag = true;
}
~
function xml_response_close_element_function($p, $element){
global $FoundStatusTag;
~
// do nothing special for now
}
~
function xml_response_handle_character_data($p, $cdata){
global $FoundStatusTag;
~
if ($FoundStatusTag) {
echo $cdata;
$FoundStatusTag = false;
}
}
?>

The example provided didn't work for me. It gave me the same string without
anything modified.
I am also looking for this solution to strip out text from some XML response
I get from posting data to a remote server. I can do it using substring
functions but I'd like something more compact and portable. (A one-liner
that I could modify for other uses as well)
Example 1:
<someXMLtags>
~<status>16664 Rejected: Invalid LTV</status>
</someXMLtags>
Example 2:
<someXMLtags>
~<status>Unable to Post, Invalid Information</status>
</someXMLtags>
I want what is inside the <status> tags.
Does anyone have a working solution how we can get the text from inside
these tags using regex?
Much appreciated,
B
