SAXFilter를 사용하여 SOAP 응답의 네임 스페이스를 제거 할 수 없습니다.

유효한 응답이 아니기 때문에 다음 SOAP 응답을 구문 분석하려고합니다. 다음 필터를 사용하여 네임 스페이스를 제거하려고하지만 오류가 발생합니다.

이것이 제가 여기서 찾은 필터 구현입니다.

NamespaceFilter

public class NamespaceFilter extends XMLFilterImpl {

    private String usedNamespaceUri;
    private boolean addNamespace;

    //State variable
    private boolean addedNamespace = false;

    public NamespaceFilter(String namespaceUri,
            boolean addNamespace) {
        super();

        if (addNamespace)
            this.usedNamespaceUri = namespaceUri;
        else 
            this.usedNamespaceUri = "";
        this.addNamespace = addNamespace;
    }



    @Override
    public void startDocument() throws SAXException {
        super.startDocument();
        if (addNamespace) {
            startControlledPrefixMapping();
        }
    }



    @Override
    public void startElement(String arg0, String arg1, String arg2,
            Attributes arg3) throws SAXException {

        super.startElement(this.usedNamespaceUri, arg1, arg2, arg3);
    }

    @Override
    public void endElement(String arg0, String arg1, String arg2)
            throws SAXException {

        super.endElement(this.usedNamespaceUri, arg1, arg2);
    }

    @Override
    public void startPrefixMapping(String prefix, String url)
            throws SAXException {


        if (addNamespace) {
            this.startControlledPrefixMapping();
        } else {
            //Remove the namespace, i.e. don´t call startPrefixMapping for parent!
        }

    }

    private void startControlledPrefixMapping() throws SAXException {

        if (this.addNamespace && !this.addedNamespace) {
            //We should add namespace since it is set and has not yet been done.
            super.startPrefixMapping("", this.usedNamespaceUri);

            //Make sure we dont do it twice
            this.addedNamespace = true;
        }
    }

}
