I have the following sample XML data that I want to parse into SimpleXML using PHP:
<?xml version="1.0" encoding="utf-8" ?> <ogr:FeatureCollection xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://ogr.maptools.org/ fire_districts.xsd" xmlns:ogr="http://ogr.maptools.org/" xmlns:gml="http://www.opengis.net/gml"> <gml:boundedBy> <gml:Box> <gml:coord><gml:X>112.921100000165</gml:X><gml:Y>-43.65832660868602</gml:Y></gml:coord> <gml:coord><gml:X>153.6407999999201</gml:X><gml:Y>-10.05939999961026</gml:Y></gml:coord> </gml:Box> </gml:boundedBy> <gml:featureMember> <ogr:IDM00007 fid="IDM00007.0"> <ogr:geometryProperty><gml:Polygon><gml:outerBoundaryIs><gml:LinearRing><gml:coordinates>153.551804332204,-28.1645084912738 153.586699999805,-28.2582999997451 153.573299999695,-28.3133 153.582500000375</gml:coordinates></gml:LinearRing></gml:outerBoundaryIs></gml:Polygon></ogr:geometryProperty> <ogr:AAC>NSW_FW001</ogr:AAC> <ogr:DIST_NO>1</ogr:DIST_NO> <ogr:DIST_NAME>Far North Coast</ogr:DIST_NAME> <ogr:STATE_CODE>NSW</ogr:STATE_CODE> <ogr:SOURCE>RFS</ogr:SOURCE> <ogr:GROUP_NAME xsi:nil="true"/> </ogr:IDM00007> </gml:featureMember> <gml:featureMember> <ogr:IDM00007 fid="IDM00007.1"> <ogr:geometryProperty><gml:Polygon><gml:outerBoundaryIs><gml:LinearRing><gml:coordinates>153.261225211474,-29.9401032948311 153.19820000033,-30.038899999935 153.20060000039,-30.1036999997551 153.214099999715</gml:coordinates></gml:LinearRing></gml:outerBoundaryIs></gml:Polygon></ogr:geometryProperty> <ogr:AAC>NSW_FW002</ogr:AAC> <ogr:DIST_NO>2</ogr:DIST_NO> <ogr:DIST_NAME>North Coast</ogr:DIST_NAME> <ogr:STATE_CODE>NSW</ogr:STATE_CODE> <ogr:SOURCE>RFS</ogr:SOURCE> <ogr:GROUP_NAME xsi:nil="true"/> </ogr:IDM00007> </gml:featureMember> </ogr:FeatureCollection>
I've tried a few different ways of loading this XML using SimpleXML, but whenever I do a print_r on the data, it just goes blank:
<?php $data = file_get_contents("fire_districts.gml"); $xml = new SimpleXMLElement($data); $xml->registerXPathNamespace('f', 'http://ogr.maptools.org/'); $xml->registerXPathNamespace('g', 'http://www.opengis.net/gml'); $gml = $xml->xpath('/f:FeatureCollection/g:featureMember'); print_r($gml); ?>
The output is as follows:
Array ( [0] => SimpleXMLElement Object ( ) [1] => SimpleXMLElement Object ( ) [2] => SimpleXMLElement Object ( ) [3] => SimpleXMLElement Object ( ) ....
What do I need to change to successfully load this GML data into an array?
Cheers, Mike

You can try to use "var_dump" to print the contents of the "$data" variable or 'echo' to see if it contains the expected data.

Try using simplexml_load_string() instead of file_get_contents().
