PHP 구문 분석 WFS XML 응답

Question

WFS 요청에서 GeoServer로 XML (또는 GML) 응답을 구문 분석하려고합니다.

내 목표는 그때 표시 할 수있는 좋은 깔끔한 배열, 수출, 등 등으로 XML을 추출하는 것입니다

내 XML은 다음과 같습니다

<?xml version="1.0" encoding="UTF-8"?> 
<wfs:FeatureCollection numberOfFeatures="52" timeStamp="2012-06-28T10:11:02.193Z" xsi:schemaLocation="http://squirrel.bis.local/bis_workspace http://squirrel.bis.local:8080/geoserver/wfs?service=WFS&amp;version=1.1.0&amp;request=DescribeFeatureType&amp;typeName=bis_workspace%3Abis_1_priority_species http://www.opengis.net/wfs http://squirrel.bis.local:8080/geoserver/schemas/wfs/1.1.0/wfs.xsd" xmlns:opengeo="http://opengeo.org" xmlns:ogc="http://www.opengis.net/ogc" xmlns:bis_workspace="http://squirrel.bis.local/bis_workspace" xmlns:world="http://world.opengeo.org" xmlns:wfs="http://www.opengis.net/wfs" xmlns:medford="http://medford.opengeo.org" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ows="http://www.opengis.net/ows" xmlns:gml="http://www.opengis.net/gml" xmlns:usa="http://usa.opengeo.org" xmlns:xlink="http://www.w3.org/1999/xlink"> 
<gml:featureMembers> 
<bis_workspace:bis_1_priority_species gml:id="bis_1_priority_species.fid--2f086452_138094a10a0_116d"> 

<bis_workspace:id>27407951</bis_workspace:id> 
<bis_workspace:gridref>SN123456</bis_workspace:gridref> 
<bis_workspace:species>Milvus milvus</bis_workspace:species> 
<bis_workspace:common>Red Kite</bis_workspace:common> 
<bis_workspace:date>2004</bis_workspace:date> 
<bis_workspace:comments> 
</bis_workspace:comments> 
<bis_workspace:family>Accipitridae</bis_workspace:family> 
</bis_workspace:bis_1_priority_species> 

<bis_workspace:bis_1_priority_species gml:id="bis_1_priority_species.fid--2f086452_138094a10a0_116e"> 
<bis_workspace:id>28064165</bis_workspace:id> 
<bis_workspace:gridref>SN123456</bis_workspace:gridref> 
<bis_workspace:species>Lutra lutra</bis_workspace:species> 
<bis_workspace:common>European Otter</bis_workspace:common> 
<bis_workspace:date>09/11/2001</bis_workspace:date> 
<bis_workspace:comments>spraint</bis_workspace:comments> 
<bis_workspace:family>Mustelidae</bis_workspace:family> 
</bis_workspace:bis_1_priority_species> 

</gml:featureMembers> 
</wfs:FeatureCollection> 

내가 말을하고 싶습니다 결과는 다음과 같이합니다 :

Array 
(
    [0] => Array 
    (
      [id] => 27407951 
      [gridref] => SN123456 
      [species] => Milvus milvus 
      [common] => Red Kite 
      [date] => 2004 
      [comments] => 
      [family] => Accipitridae 
     ) 

[1] => Array 
    (
     [id] => 28064165 
     [gridref] => SN123456 
     [species] => Lutra lutra 
     [common] => European Otter 
     [date] => 09/11/2001 
     [comments] => spraint 
     [family] => Mustelidae 
    ) 

[2] => Array 
    (
     [id] => 27516850 
     [gridref] => SN123456 
     [species] => Tyto alba 
     [common] => Barn Owl 
     [date] => 2004 
     [comments] => Pair, nest box in tree, 2 chicks 
     [family] => Tytonidae 
    ) 

를)

등 등

다음 코드를 사용하고 있습니다. 작동하지만 어리석게 비효율적입니다. XML의 모든 레코드에 대해 코드는 전체 XML 응답을 구문 분석해야합니다. 20-30 개의 레코드 만 있으면이 XML 응답에 수천 개의 레코드가 포함될 수 있습니다.

XML 파일을 1 스윕 만 사용하여이 어레이를 빌드하는 방법이 있습니까? 나는 또한 WFS XML의 네임 스페이스를 처리하기 위해 고투 한

//Parse the XML 
    $xml = simplexml_load_string($wfs_reply, NULL, NULL, "http://squirrel.bis.local/bis_workspace"); 
    $xml->registerXPathNamespace('wfs', 'http://www.opengis.net/wfs'); 
    $xml->registerXPathNamespace('gml', 'http://www.opengis.net/gml'); 
    $xml->registerXPathNamespace('bis_workspace', 'http://squirrel.bis.local/bis_workspace'); 

    $count = 0; 
    $feature_members_array = array(); 
    $feature_members_layer_path = "//bis_workspace:" . $layer_name; //I.e. '//bis_workspace:bis_1_priority_species' 
    foreach($xml->xpath($feature_members_layer_path) as $feature_members_raw) 
    { 

     $feature_member_id = $feature_members_raw->xpath('//bis_workspace:id'); 
      $feature_members_array[$count]['id'] = (string)$feature_member_id[$count]; 
     $feature_member_gridref = $feature_members_raw->xpath('//bis_workspace:gridref'); 
      $feature_members_array[$count]['gridref'] = (string)$feature_member_gridref[$count]; 
     $feature_member_species = $feature_members_raw->xpath('//bis_workspace:species'); 
      $feature_members_array[$count]['species'] = (string)$feature_member_species[$count]; 
     $feature_member_common = $feature_members_raw->xpath('//bis_workspace:common'); 
      $feature_members_array[$count]['common'] = (string)$feature_member_common[$count]; 
     $feature_member_date = $feature_members_raw->xpath('//bis_workspace:date'); 
      $feature_members_array[$count]['date'] = (string)$feature_member_date[$count]; 
     $feature_member_comments = $feature_members_raw->xpath('//bis_workspace:comments'); 
      $feature_members_array[$count]['comments'] = (string)$feature_member_comments[$count]; 
     $feature_member_family = $feature_members_raw->xpath('//bis_workspace:family'); 
      $feature_members_array[$count]['family'] = (string)$feature_member_family[$count]; 

     $count ++; 
    } 

많은 감사, 스티브

Answer 1

:

다음은 PHP입니다. 내 솔루션은 JSON으로 전환하는 것이 었습니다!

당신의 WFS가 지원하는 경우

, 당신은 WFS 요청에 outputFormat=json을 추가 할 수 있으며 일이 훨씬 쉽게 :)
