我目前正在接收来自我调用的SOAP调用的WSResponse，并且我正在尝试解析响应。这是响应的样子。

我不需要所有的元素，但我需要的是我想要放入POJO。到目前为止，我有什么更好的办法吗？这就是我所做的。
WSResponse wsresponse = request.post(soapRequest).get(TIMEOUT);
Document response = wsresponse.asXml();
List < TroubleTicket > tickets = Lists.newArrayList();
Node node = response.getElementsByTagNameNS("*", QUERY_LIST_RESPONSE).item(0);
NodeList children = node.getChildNodes();
Logger.info("Parsing tickets from response, found " + children.getLength() + " tickets.");
for (int counter = 0; counter < children.getLength(); counter++) {
NodeList grandChildren = children.item(counter).getChildNodes();
for (int childCounter = 0; childCounter < grandChildren.getLength(); childCounter++) {
TroubleTicket ticket = new TroubleTicket();
String element = grandChildren.item(childCounter).getNodeName();
String elementText = grandChildren.item(childCounter).getTextContent();
switch (element) {
case "Summary":
ticket.setSummary(elementText);
break;
case "Notes":
ticket.setNotes(elementText);
break;
}
}
}

继MIkCode's comment之后，我还建议使用Scala将XML解组为模型对象。当您使用面向Scala的Play Framework时，至少可以探索使用Scala进行XML处理的选项。
这是Scala中XML处理的粗略说明。即使您不熟悉Scala，希望您可以看到该处理基于使用类似XPath的选择器，并且代码比使用Java中的Document API更简洁。
WSResponse wsResponse = request.post(soapRequest).get(TIMEOUT);
HelpDeskServiceResponse response = new HelpDeskServiceResponse(wsResponse.getBody())
// response.tickets() will now give you a Scala collection of tickets.
import scala.xml.XML
class HelpDeskServiceResponse(xml : String) {
lazy val xmlDoc = XML.load(xml)
// Matches on any 'getListValues' descendants and transforms each matching
// element to a ticket object
lazy val tickets = (xmlDoc \\ "getListValues").map(node => new HelpDeskTicket(node))
}
import scala.xml.Node
class HelpDeskTicket(node : Node) {
lazy val summary = node \ "Summary"
lazy val notes = node \ "Notes"
}

我最终做的是获取WSResponse并调用response.asXml（）;这返回了一个XML文档，我循环查找我需要的字段，并保存在字符串列表中。然后，我构建了Json对象，以便在循环响应时将其返回给客户端。
Node node = response.getElementsByTagNameNS("*", elementTagName).item(0);
NodeList children = node.getChildNodes();
ArrayNode responseTickets = Json.newObject().arrayNode();
for (int counter = 0; counter < children.getLength(); counter++) {
ObjectNode ticketNode = getTicketFromResponse(children.item(counter).getChildNodes(), responseFields);
if (ticketNode.size() != 0) {
responseTickets.add(ticketNode);
}
}
return responseTickets;
getTicketsFromResponse方法：
ObjectNode ticketNode = Json.newObject();
for (int childCounter = 0; childCounter < nodeList.getLength(); childCounter++) {
String element = nodeList.item(childCounter).getNodeName();
String elementText = nodeList.item(childCounter).getTextContent();
element = element.substring(4, element.length());
if (responseFields.contains(element)) {
ticketNode.put(element, elementText);
if (SUMMARY_FIELD.equals(element) && !Strings.isEmpty(elementText)) {
// Retrieve the id of the resource
try {
Long id = null;
Matcher matcher = Pattern.compile(SERVICE_ID_PATTERN).matcher(elementText);
if (matcher.find()) {
String matched = matcher.group(0);
Matcher numberMatcher = Pattern.compile("\\d+").matcher(matched);
if (numberMatcher.find()) {
id = Long.parseLong(numberMatcher.group(0));
Service service = Service.findByIdNotNull(id);
ticketNode.put(SERVICE_NAME_FIELD,
String.format(SERVICE_NAME_FORMAT, service.getName(), service.getUSI()));
}
}
ticketNode.put(SERVICE_ID_FIELD, id);
} catch (NullPointerException exception) {
Logger.error("Unable to get the service for the configuration item", exception);
} catch (NumberFormatException exception) {
Logger.error("Unable to parse the id from the summary field. ");
} catch (ResourceNotFoundException exception) {
Logger.error("Unable to get the service.", exception);
}
} else if (SUBMIT_DATE_FIELD.equals(element) && !Strings.isEmpty(elementText)) {
try {
Date submitDate = new SimpleDateFormat(RESPONSE_DATE_FORMAT).parse(elementText);
elementText = new SimpleDateFormat(SKYLIGHT_DATE_FORMAT).format(submitDate);
ticketNode.put(element, elementText);
} catch (ParseException exception) {
Logger.error("Unable to parse the submit date. ", exception);
}
}
}
}
return ticketNode;
