我对这个很困惑。给定以下xml:
<sch:eventList>
<sch:event>
<sch:eventName>Event One</sch:eventName>
<sch:locationName>Location One</sch:locationName>
</sch:event>
<sch:event>
<sch:eventName>Event Two</sch:eventName>
<sch:locationName>Location Two</sch:locationName>
</sch:event>
</sch:eventList>
使用 JDOM 时使用以下代码:
XPath eventNameExpression = XPath.newInstance("//sch:eventName");
XPath eventLocationExpression = XPath.newInstance("//sch:eventLocation");
XPath eventExpression = XPath.newInstance("//sch:event");
List<Element> elements = eventExpression.selectNodes(requestElement);
for(Element e: elements) {
System.out.println(eventNameExpression.valueOf(e));
System.out.println(eventLocationExpression.valueOf(e));
}
控制台显示:
Event One
Location One
Event One
Location One
我错过了什么?
