Regular expression to parse SOAP response

Question

I found several solutions for converting SOAP response into a object, but none of them work. I get my soap response as an xml string, e.g.:

 $response = '
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://xxx.company.com" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
      <SOAP-ENV:Body>
        <ns1:DataResponse>
          <DataReturn xsi:type="ns1:OutXT">
            <Errors SOAP-ENC:arrayType="ns1:Errors[12]" xsi:type="ns1:ErrorsArray">
              <item xsi:type="ns1:Errors">
                <ErrorItem xsi:type="xsd:string">Access</ErrorItem>
                <DescErrors xsi:type="xsd:string">User not found</DescErrors>
              </item>
              <item xsi:type="ns1:Errors">
                <ErrorItem xsi:type="xsd:string">Client check</ErrorItem>
                <DescErrors xsi:type="xsd:string">Report 85 completed</DescErrors>
              </item>
            </Errors>
            <ClientCategory xsi:type="xsd:string">A</ClientCategory>
            <Premium xsi:type="ns1:Premium">
              <Price xsi:type="xsd:int">2509</Price>
              <Coef xsi:type="xsd:float">4.558</Coef>
              <Discount xsi:type="xsd:int">35</Discount>
            </Premium>
            <Sample xsi:type="xsd:int">0</Sample>
            <Status xsi:type="xsd:string">OK</Status>
          </DataReturn>
        </ns1:DataResponse>
      </SOAP-ENV:Body>
    </SOAP-ENV:Envelope>';

And I need to get rid of all the namespaces including the colon and all the attributes so the outcome in this case would be:

<Envelope>
 <Body>
    <DataResponse>
      <DataReturn>
        <Errors>
          <item>
            <ErrorItem>Access</ErrorItem>
            <DescErrors>User not found</DescErrors>
          </item>
          <item>
            <ErrorItem>Client check</ErrorItem>
            <DescErrors>Report 85 completed</DescErrors>
          </item>
        </Errors>
        <ClientCategory>A</ClientCategory>
        <Premium>
          <Price>2509</Price>
          <Coef>4.558</Coef>
          <Discount>35</Discount>
        </Premium>
        <Sample>0</Sample>
        <Status>OK</Status>
      </DataReturn>
    </DataResponse>
  </Body>
</Envelope>

I found some regular expression that allegedly does that job but it simply doesn't work either:

$response = preg_replace("/(<\/?)(\w+):([^>]*>)/", "$1$2$3", $response);

Well you could replace the matches of this expression with an empty string:

(((?<=<\/)|(?<=<))[^\/\s]*?:|\s?[^\s]+=".*?")

See this in action at Regex101

Explanation

This Expression matches

(?<=<)|(?<=<\/))[^\/\s]*?: Namespaces from starting and closing xml-tags (everythis after < or </ until inclusive :)
\s?[^\s]+=".*?" basically all xml-attributes and their prepending whitespace

You edited your answer but it seems that the original version was working.. This second one doesn't work.. – Totallama Nov 01 '16 at 14:21
the expression is the same, i just removed surrounding braces – nozzleman Nov 01 '16 at 14:23
you should check if you really need the surounding braces, they could slow the expression down a lot btw. – nozzleman Nov 01 '16 at 14:27
Wait, it doesn't work!! It deletes \ in closing tags as well. converts to instead of – Totallama Nov 01 '16 at 14:43
oh, right, then we should exclude that ;) done, see my edit – nozzleman Nov 01 '16 at 14:50
glad i could help – nozzleman Nov 01 '16 at 16:11
