</Config>比如我要找到:沥青路面-龟裂-轻的power="0.6"中的0.6,但是我缺要根据PitchFace里的code="248"以及下面的 <row code="01"下面的<prop scope="轻" power="0.6" scopeCode="1"/>中的scopeCode="1"来找这个0.6该如何读取寻找.
最好是能用jdom.其他的也无所谓. 谢谢大家了.

Answer 1

用dom4j吧，看看这个http://blog.csdn.net/yizhizouxiaqu/article/details/4977122

Answer 2

用dom4j:
String fileName = "****.xml";
ReadXml test = new ReadXml();
Document doc = test.read(fileName);
Element root = test.getRootElement(doc);
然后遍历config这个根节点下的PitchFace 
// 遍历名称为PitchFace的节点
for (Iterator i = root.elementIterator("PitchFace"); i.hasNext();) {
Element pf = (Element) i.next();
// 遍历PitchFace的属性
for (Iterator it = pf.attributeIterator(); it.hasNext();) {
Attribute attribute = (Attribute) it.next();
System.out.println(attribute.getName() + ":"
+ attribute.getValue());
} System.out.println(pf.elementText("row"));
System.out.println(pf.elementText("prop"));
// 遍历PitchFace的子节点“prop”的属性
for (Iterator it = pf.element("prop").attributeIterator(); it
.hasNext();) {
Attribute attribute = (Attribute) it.next();
System.out.println(attribute.getName() + ":"
+ attribute.getValue());
} System.out.println(pf.elementText("prower"));
}一层层遍历吧
