我有来自 Web 服务的 XML 请求。看起来像这样。那么，如何获取orderId值呢？我从来没有在 Java 中使用过 XML。

<order1s uri="http://mywebsite/rest/create_order">
<order1 uri="http://mywebsite/rest/create_order/401/"> 
<customer uri="http://mywebsite/rest/create_order/401/customer/">
<name/>
<passengerId>123</passengerId>
<phone/>
<rating>0.0</rating>
<restToken>
985y3289y5v43535v032m0v3v0b0jcrmjsa9w20m02umc3
</restToken>
<surname/>
</customer>
<offerCollection uri="http://mywebsite/rest/create_order/401/offerCollection/"/>
<orderId>401</orderId>
<orderWaypointsCollection uri="http://mywebsite/rest/create_order/401/orderWaypointsCollection/">
<orderWaypoints uri="http://mywebsite/rest/create_order/401/orderWaypointsCollection/null/">
<isStartPoint>true</isStartPoint>
<latitude>50.505463</latitude>
<longitude>30.44121</longitude>
<norder uri="http://mywebsite/rest/create_order/401/orderWaypointsCollection/null/norder/"/>
</orderWaypoints>
<orderWaypoints uri="http://mywebsite/rest/create_order/401/orderWaypointsCollection/null/">
<isStartPoint>false</isStartPoint>
<latitude>50.4501</latitude>
<longitude>30.5234</longitude>
<norder uri="http://mywebsite/rest/create_order/401/orderWaypointsCollection/null/norder/"/>
</orderWaypoints>
</orderWaypointsCollection>

</order1>
</order1s>

I have XML-request from web service. It looks like this. So, how can I get orderId value? I never work with XML in Java.

<order1s uri="http://mywebsite/rest/create_order">
<order1 uri="http://mywebsite/rest/create_order/401/"> 
<customer uri="http://mywebsite/rest/create_order/401/customer/">
<name/>
<passengerId>123</passengerId>

<surname/>
</customer>
<offerCollection uri="http://mywebsite/rest/create_order/401/offerCollection/"/>
<orderId>401</orderId>
<orderWaypointsCollection uri="http://mywebsite/rest/create_order/401/orderWaypointsCollection/">
<orderWaypoints uri="http://mywebsite/rest/create_order/401/orderWaypointsCollection/null/">
<isStartPoint>true</isStartPoint>
<latitude>50.505463</latitude>
<longitude>30.44121</longitude>
<norder uri="http://mywebsite/rest/create_order/401/orderWaypointsCollection/null/norder/"/>
</orderWaypoints>

<isStartPoint>false</isStartPoint>
<latitude>50.4501</latitude>

我建议使用 XPath：

它将类似于：

XPath xpath = XPathFactory.newInstance().newXPath();
String expression = "orderId";
InputSource inputSource = new InputSource(xmlInputStreamOrReaderOrSomethingElse). 
String id = (String) xpath.evaluate(expression, inputSource, XPathConstants.STRING);

更新：

表达式必须为 "//orderId"：示例

InputSource inputSource = new InputSource(xmlInputStreamOrReaderOrSomethingElse). 
String id = (String) xpath.evaluate(expression, inputSource, XPathConstants.STRING);

Updated:

expression must be "//orderId": example

如果您想使用平台内置的工具来解析它，您可以使用 SAX DefaultHandler。这里有很多指向教程的答案。

如果您只需要 orderId 值而不需要任何其他值，那么我建议仅使用正则表达式，例如：

<orderId>(\d+)<\/orderId>

If you want to parse it using the facilities built into the platform, you can use a SAX DefaultHandler. There are a bunch of answers here that point to tutorials.

If you just need the orderId value and none of the other values, then I would suggest just using a regular expression like:
