1.xml文档
<?xml version="1.0" encoding="UTF-8"?> <?xml-stylesheet type="text/xsl" href="configuration.xsl"?> <cons> <con number="test">this is a test</con> </cons>
2.读取xml中的属性值
SAXReader saxReader = new SAXReader(); Document document=saxReader.read("D:/123.xml"); Element rootElement=document.getRootElement(); List<Element>stEls=rootElement.elements(); String test=""; for(Element stEl:stEls){ String number=stEl.attributeValue("number"); if(number.equals("test")){ test=stEl.getText(); } }
3.修改xml中的属性值
SAXReader saxReader = new SAXReader(); Document document=saxReader.read("D:/123.xml"); Element rootElement=document.getRootElement(); List<Element>stEls=rootElement.elements(); for(Element stEl:stEls){ String number=stEl.attributeValue("number"); if(number.equals("test")){ stEl.setText(test); } } File f = new File("D:\\123.xml"); XMLWriter output = new XMLWriter(new FileWriter(f)); output.write(document); output.close();
