Parsing Soap Response in java

[emmn...@gmail.com]

Hi,i need to parse a soap response from an xml fileb in java to get some specific values of it .For example ,i need to have the value v1 of string parameter in operationname1 and v2 of string parameter of operationname2.i tried with some tuto in the net but it doesn't work for me .I will be very thankful if you can help me .
Here is the soap response.xml.


<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="...">
<soapenv:Body>
<ns1:CommandResponseData xmlns:ns1="...">
<ns1:CommandResult>
<ns1:TransactionResult>
<ns1:OperationResult>
<ns1:Operation name="operationname1" modifier="modify1">
<ns1:ParameterList>
<ns1:StringParameter name="n1">v1</ns1:StringParameter>
<ns1:DateTimeParametername="d1">value</ns1:DateTimeParameter>
</ns1:ParameterList>
</ns1:Operation>

</ns1:Operation>
<ns1:Operation name="operationname2" modifier="modify2">
<ns1:ParameterList>
<ns1:StringParameter name="c1">v2</ns1:StringParameter>
</ns1:ParameterList>
</ns1:Operation>
</ns1:OperationResult>
</ns1:TransactionResult>
</ns1:CommandResult>
</ns1:CommandResponseData>
</soapenv:Body>
</soapenv:Envelope>

I parse the soap responses from Amazon that tells me which books they
have in stock.

You need a Jax-compatible descriptor of the soap records. It then
generates you Java sourcecode to parse the incoming stream.

You then navigate the tree to pick out what you want.

see http://mindprod.com/jax.html

Amazon provides a descriptor file
AWSECommerceService.wsdl

that looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<definitions xmlns="http://schemas.xmlsoap.org/wsdl/"
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:tns="http://webservices.amazon.com/AWSECommerceService/2011-08-01"
targetNamespace="http://webservices.amazon.com/AWSECommerceService/2011-08-01">
<types>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:tns="http://webservices.amazon.com/AWSECommerceService/2011-08-01"

0) That is not the SOAP result as it is not well formed XML.

I will assume it looks like:

<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="...">
<soapenv:Body>
<ns1:CommandResponseData xmlns:ns1="...">
<ns1:CommandResult>
<ns1:TransactionResult>
<ns1:OperationResult>
<ns1:Operation name="operationname1"
modifier="modify1">
<ns1:ParameterList>
<ns1:StringParameter
name="n1">v1</ns1:StringParameter>
<ns1:DateTimeParameter
name="d1">value</ns1:DateTimeParameter>
</ns1:ParameterList>
</ns1:Operation>

<ns1:Operation name="operationname2"
modifier="modify2">
<ns1:ParameterList>
<ns1:StringParameter
name="c1">v2</ns1:StringParameter>
</ns1:ParameterList>
</ns1:Operation>
</ns1:OperationResult>
</ns1:TransactionResult>
</ns1:CommandResult>
</ns1:CommandResponseData>
</soapenv:Body>
</soapenv:Envelope>

1) If you are process XML when you are doing SOAP then you are most
like doing it wrong. You should be generating stub code from the
WSDL and just make a method call and not worry about XML at all.

2) If you really need to parse the response manually, then I will
recommend using XPath.

Example reading the above XML from a disk file soap.xml:

import java.io.FileReader;
import java.io.IOException;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.xpath.XPath;
import javax.xml.xpath.XPathConstants;
import javax.xml.xpath.XPathExpressionException;
import javax.xml.xpath.XPathFactory;

import org.w3c.dom.Document;
import org.w3c.dom.Node;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;

public class ManualSoapParse {
public static void main(String[] args) throws
ParserConfigurationException, SAXException, IOException,
XPathExpressionException {
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(false);
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new InputSource(new
FileReader("/work/soap.xml")));
XPath xpath = XPathFactory.newInstance().newXPath();
Node n1 =
(Node)xpath.evaluate("//Envelope/Body/CommandResponseData/CommandResult/TransactionResult/OperationResult/Operation[@name='operationname1']/ParameterList/StringParameter[@name='n1']/text()",
doc.getDocumentElement(), XPathConstants.NODE);
System.out.println(n1.getNodeValue());
Node c1 =
(Node)xpath.evaluate("//Envelope/Body/CommandResponseData/CommandResult/TransactionResult/OperationResult/Operation[@name='operationname2']/ParameterList/StringParameter[@name='c1']/text()",
doc.getDocumentElement(), XPathConstants.NODE);
System.out.println(c1.getNodeValue());
}
}

Note that I cheated and ignored namespaces. You can handle namespaces if
you need to or want to.

hi Arne ,thank you for your response ,i used the 2nd issue to manually parse the soap response and it gives me errors in this line (System.out.println(n1.getNodeValue());)
I have even added the namespace context by adding this code NamespaceContext ctx = new NamespaceContext() {

public String getNamespaceURI(String prefix) {
String uri;
if (prefix.equals("ns1")) {
uri = "uri of ns1";
} else {
uri = null;
}
return uri;
}

public String getPrefix(String namespaceURI) {
throw new UnsupportedOperationException("Not supported yet.");
}

public Iterator getPrefixes(String namespaceURI) {
throw new UnsupportedOperationException("Not supported yet.");
}
};
and still haven't succeed to get the values .
Thanks in advance for your help .

What you want would be ease to do with DOM plus maybe some XPath if the
XML where valid, which it is not.

Sorry but how can i parse the soap response if it isn't with xml parsing ?

[Silvio]

It would be with XML parsing IF it where actual XML. What you have
provided is not valid XML and can therefore not be parsed with an XML
parser. Are you sure you posted an actual sample of what you are trying
to parse?

Do you expect us to be able to guess what the problem is without you
telling us what "gives me errors" covers?

If you have a strong desire for some unmaintainable code, then there are
lots of possibilities in String indexOf and String substring.

There are two problems with this XML
Try fixing them and then parse again.
