Question

This question already has an answer here:

• Reference - how do I handle namespaces (tags and attributes with colon in) in SimpleXML? 1 answer

I have XML-answer, as shown lower.

How to parse correctly this answer by php & SimpleXml? Now I use 'str_replace" to remove strings, such as "soap:Envelope", "simplexml_load_string" and etc. Are there more correct variants for parsing string on to get fields "code" and "message"?

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><SOAP-ENV:Envelope xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <SOAP-ENV:Body>
    <example:app_response xmlns:m="urn:QWERTY/YTREWQ/application">
      <code>0</code>
      <message/>
    </example:app_response>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope></soap:Body></soap:Envelope>

</div>

If you have this xml as string then I would get the code with preg_match call. With pattern like <code>(.+)</code>
