Need help!
我有 xml 并使用 Xstream 将其转换为 java 对象，当我将相同的 java 对象转换为 xml 并验证 xml 标签及其值时，我找不到值 xml 标签的文本：
XML :
<?xml version="1.0" encoding="UTF-8"?>
<record name="ncwtrial.xml" type="content">
<item name="Root">
<value>
<item name="Main">
<value>
<item name="ContentID">
<value>007NMG</value>
</item>
</value>
</item>
</value>
</item>
</record>
// 但是在验证时得到这个：（值没有到来）
<?xml version="1.0" encoding="UTF-8"?>
<record name="ncwtrial.xml" type="content">
<item name="Root">
<value>
<item name="Main">
<value>
<item name="ContentID">
<value/>
</item>
</value>
</item>
</value>
</item>
</record>
//我的java类：
public static void main(String[] args) {
// TODO Auto-generated method stub
XStream xstream = new XStream(new DomDriver());
xstream.alias("record",Record.class);
xstream.alias("item",Item.class);
xstream.alias("value",Value.class);
// use attribute
xstream.useAttributeFor("name", String.class);
xstream.useAttributeFor("type", String.class);
xstream.addImmutableType(Value.class);
xstream.addImplicitCollection(Item.class, "value");
xstream.addImplicitCollection(Value.class, "item");
// xstream.aliasType("value", String.class);
xstream.processAnnotations(Item.class);
xstream.processAnnotations(Value.class);
Record record = (Record) xstream.fromXML(new File("C:/pankaj/temp/original.xml"));
// verifying Java object by converting it back to XML
System.out.println(xstream.toXML(record));
}
// Record.java
