1，将xml字符串解析为xml
Document doc = DocumentHelper.parseText(xml); // 将字符串转为XML
2，遍历xml通过指定一个参数获取其他参数的值
xml文件：
<nodes> <node key=‘key0‘ value=‘value0‘ /> <node key=‘key1‘ value=‘value1‘ /> <node key=‘key2‘ value=‘value2‘ /> <node key=‘key3‘ value=‘value3‘ /> <node key=‘key4‘ value=‘value4‘ /> </nodes>
方法：
import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;
//----------------
public String getXmlvalueByKey(String xmlString, String key) {
String value = null;
Element placard = null;
Document document = null;
SAXReader reader = new SAXReader();
try {
// document = reader.read(new File("E:/temp/test.xml")); //解析xml文件
document = DocumentHelper.parseText(xmlString); // 解析xml字符串
placard = document.getRootElement();
Element item = (Element) placard.selectSingleNode("/nodes/node[@key=‘" + key + "‘]");
if (item != null) {
value = item.attributeValue("value");
}
} catch (DocumentException e) {
e.printStackTrace();
}
return value;
}
测试方法：
@Test
public void test1() throws Exception{
String xmlString ="<nodes><node key=‘key0‘ value=‘value0‘ /><node key=‘key1‘ value=‘value1‘ /><node key=‘key2‘ value=‘value2‘ /><node key=‘key3‘ value=‘value3‘ /><node key=‘key4‘ value=‘value4‘ /></nodes>";
//查找xml文件key的值
String value=new ExcelOperationUtil().getXmlvalueByKey(xmlString,"key1");
System.out.println(value);//输出结果value1
}
