如何使用XStream（部分）反序列化有错误的xml

Question

<list>
 <item>
  <id>123</id>
  <name>someName</name>
 </item>
 <item>
  <id>234</id>
  <name>anotherName</name>
 </item>
 <item>
  <id>345</id>
  <name>aThirdName</name>
 </item>
</list>

class ListXML {
 public List<ItemXML> list;
}

class ItemXML {
 public String id;
 public String name;
}

XStream xstream = new XStream(new DomDriver());
xstream.alias("list", ListXML.class);
xstream.alias("item", ItemXML.class);
xstream.addImplicitCollection(ListXML.class, "item");
ListXML result = (ListXML) xstream.fromXML(in);

<list>
 <item>
  <id>123</id>
  <name>someName</name>
 </item>
 <item>
  <id>234</id>
  <aTagUnknownToMe>blabla</aTagUnknownToMe>
 </item>
 <item>
  <id>345</id>
  <name>aThirdName</name>
 </item>
</list>

Answer 1

是的，你可以。

XStream xstream = new XStream();
xstream.ignoreUnknownElements();

或

XStream xstream = new XStream();
xstream.ignoreUnknownElements("somePattern");

这些方法从XStream1.4.5开始就可用了。
