PHP XML - 将重复元素和子元素提取到数组

Question

I using the built in PHP SOAP function and CURL to send an request and get a response from an .Net ASMX web service.

Currently I´m receiving the response as an XML, but need some help with extracting information from the XML as the data I need is nested deep in the XML. For example extract only what I need and convert it to an array in order to send it directly to an database.

The XML starts as follows:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
  <GetViewBidResponse xmlns="http://domain.com/SolutionWebService">
     <GetViewBidResult>
        <message>OK</message>
        <table>
           <xs:schema id="NewDataSet" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" xmlns:msprop="urn:schemas-microsoft-com:xml-msprop">
              <xs:element name="NewDataSet" msdata:IsDataSet="true" msdata:MainDataTable="Bidrod" msdata:UseCurrentLocale="true">
                 <xs:complexType>
                    <xs:choice minOccurs="0" maxOccurs="unbounded">
                       <xs:element name="Bid">
                          <xs:complexType>
                             <xs:sequence>
                                <xs:element name="rows" msprop:ColumnId="1" type="xs:string" minOccurs="0"/>
                                <xs:element name="Queue" msprop:ColumnId="2" type="xs:string" minOccurs="0"/>
                                <xs:element name="Running" msprop:ColumnId="3" type="xs:string" minOccurs="0"/>

                                <xs:element name="Done" msprop:ColumnId="6" type="xs:string" minOccurs="0"/>
                                <xs:element name="Agree" msprop:ColumnId="7" type="xs:string" minOccurs="0"/>
                                <xs:element name="Canceled" msprop:ColumnId="8" type="xs:string" minOccurs="0"/>
                                <xs:element name="Hold" msprop:ColumnId="9" type="xs:string" minOccurs="0"/>
                                <xs:element name="Test" msprop:ColumnId="10" type="xs:string" minOccurs="0"/>
                                <xs:element name="All" msprop:ColumnId="11" type="xs:string" minOccurs="0"/>
                             </xs:sequence>
                          </xs:complexType>
                       </xs:element>
                    </xs:choice>
                 </xs:complexType>
              </xs:element>
           </xs:schema>

                 <Bid diffgr:id="Bid2" msdata:rowOrder="1" diffgr:hasChanges="inserted">
                    <rows>1</rodun>
                    <Queue>Testqueue2</Queue>
                    <Running>23</Running>
                    <New>q2</New>
                    <Working>27</Working>
                    <Done>48</Lokið>
                    <Agree>11</Agree>
                    <Canceled>827</Canceled>
                    <Hold>31</Hold>
                    <Test>10</Test>
                    <All>402</All>
                 </Bid>
                 <Bid diffgr:id="Bid3" msdata:rowOrder="2" diffgr:hasChanges="inserted">
...shortened, this continues from "diffgr:id="Bid1" to "diffgr:id="Bid97"...

What I would like to do is extract all child elements under each element <Bid diffgr:id="Bid1" (that starts after the DocumentElement element). It would be great to end with an array that has only the following info:

[DocumentElement] => Array ( // Optional
[Bid] => Array (          // Optional
  [0] => Array (
    [rows] => 1
    [Queue] => Testqueue1
    [Running] => 1
    [New] => 2
    [Working] => 7
    [Done] => 4802
    [Agree] => 1
    [Canceled] => 87
    [Hold] => 3
    [Test] => 0
    [All] => 4902 )
  [1] => Array (
    [rows] => 1
    [Queue] => Testqueue2
    [Running] => 1
    [New] => 4
    [Working] => 3
  ... and continues with all "Bid diffgr:id="BidXX" (number can reach 99) ...

If I can get help with extracting only what I need to an array, then I could manage the rest (adding them to an database).

I have been looking at xpath but with no success binding it to the correct xpath element. This is what I tried but with no luck:

$xml = simplexml_load_string($response);
$id = $xml->xpath("Bid[@id=Bid*]");  // Not sure how to use the wildcard
var_dump($id);

I have also been able to convert the whole XML to an array by using XML2ARRAY but then I still need to extract only what I need stated above.

Any help would be appreciated.

Answer 1

I see the advantage of the SoapClient, but want to answer the xpath-part:

$results = $xml->xpath("//Bid"); 

will select all <Bid>nodes and their children. To access those:

foreach ($results as $result) {

    echo $result->rows . "<br />";

}

This node in your XML seems to be broken, though:

<rows>1</rodun>
