求命名空间核心代码。
byte[] bytes = xmlStr.getBytes();
InputStream in = new ByteArrayInputStream(bytes);
InputStreamReader strInStream = new InputStreamReader(in, "UTF-8");
HashMap xmlMap = new HashMap();
xmlMap.put("xs", "http://tempuri.org/");
reader.getDocumentFactory().setXPathNamespaceURIs(xmlMap);
document = reader.read(strInStream);
Element element1 = (Element) document
.selectSingleNode("GetDanPanHQResponse/GetDanPanHQResult/xs:schema/xs:element/xs:complexType/xs:choice/xs:element/xs:complexType/xs:sequence");
element1是null。
