[jira] [Created] (XALANJ-2629) Trasformation using Xalan removes multiple namespaces from XML
Lavanya Hegde created XALANJ-2629:
-------------------------------------
Summary: Trasformation using Xalan removes multiple namespaces from XML
Key: XALANJ-2629
URL: https://issues.apache.org/jira/browse/XALANJ-2629
Project: XalanJ2
Issue Type: Bug
Security Level: No security risk; visible to anyone (Ordinary problems in Xalan projects. Anybody can view the issue.)
Components: transformation
Reporter: Lavanya Hegde
Assignee: Gary D. Gregory
Use below Java code to transform an xml string using xsl
package main;
import java.io.StringReader;
import java.io.StringWriter;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;
public class testwsdl {
static String xmlIn = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>\r\n" +
"<AssignMessage async=\"false\" continueOnError=\"false\" enabled=\"true\" name=\"SetWSDL\">\r\n" +
" <Set>\r\n" +
" <Payload>\r\n" +
" <wsdl:definitions xmlns:wsdl=\"http://schemas.xmlsoap.org/wsdl/\" targetNamespace=\"urn:sap-com:document:sap:soap:functions:mc-style\" xmlns:n1=\"urn:sap-com:document:sap:rfc:functions\" xmlns:wsp=\"http://schemas.xmlsoap.org/ws/2004/09/policy\" xmlns:tns=\"urn:sap-com:document:sap:soap:functions:mc-style\" xmlns:http=\"http://schemas.xmlsoap.org/wsdl/http/\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:wsoap12=\"http://schemas.xmlsoap.org/wsdl/soap12/\" xmlns:soap=\"http://schemas.xmlsoap.org/wsdl/soap/\" xmlns:mime=\"http://schemas.xmlsoap.org/wsdl/mime/\" xmlns:wsu=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\">\r\n" +

"</AssignMessage>";
static String xsl = "<?xml version=\"1.0\"?>\r\n" +
"<xsl:stylesheet version=\"1.0\"\r\n" +
" xmlns:xsl=\"http://www.w3.org/1999/XSL/Transform\">\r\n" +
"\r\n" +
" <xsl:output indent=\"yes\" method=\"xml\" encoding=\"utf-8\" />\r\n" +
"\r\n" +

" <xsl:template priority=\"10\"\r\n" +

"</xsl:stylesheet>";
public static void main(String[] args) throws Exception {
StreamSource xslSource = new StreamSource(new StringReader(xsl));
StreamSource xmlInSource = new StreamSource(new StringReader(xmlIn));
Transformer tf = TransformerFactory.newInstance().newTransformer(xslSource);
StringWriter xmlOutWriter = new StringWriter();
tf.transform(xmlInSource, new StreamResult(xmlOutWriter));
System.out.println(xmlOutWriter.toString());
}
}
Expected output is:
<?xml version="1.0" encoding="utf-8"?><AssignMessage async="false" continueOnError="false" enabled="true" name="SetWSDL">
<Set>
<Payload>
<wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:n1="urn:sap-com:document:sap:rfc:functions" xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy" xmlns:tns="urn:sap-com:document:sap:soap:functions:mc-style" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsoap12="http://schemas.xmlsoap.org/wsdl/soap12/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" targetNamespace="urn:sap-com:document:sap:soap:functions:mc-style">
</wsdl:definitions>
</Payload>
</Set>
<AssignVariable>
<Name>name</Name>
<Value/>
<Ref/>
</AssignVariable>
<IgnoreUnresolvedVariables>true</IgnoreUnresolvedVariables>
<AssignTo createNew="false" transport="http" type="request"/>
</AssignMessage>
It works when Trasformer from default library from JDK is used.
Output when maven xalan library with any version is used:
<?xml version="1.0" encoding="utf-8"?><AssignMessage async="false" continueOnError="false" enabled="true" name="SetWSDL">
<Set>
<Payload>
<wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" targetNamespace="urn:sap-com:document:sap:soap:functions:mc-style">
</wsdl:definitions>
</Payload>
</Set>
<AssignVariable>
<Name>name</Name>
<Value/>
<Ref/>
</AssignVariable>
<IgnoreUnresolvedVariables>true</IgnoreUnresolvedVariables>
<AssignTo createNew="false" transport="http" type="request"/>
</AssignMessage>
You can observe that multiple namespaces are removed.
