XML EXT 

解析xml字符串，如下

public static void main(String[] args) {
        //System.out.println("cccc");
        String fStr="<?xml version='1.0' encoding='UTF-8'?>" +
                "<ROOT test='test123' cod='cod123'><Name>AAA</Name><Number>BBB</Number>" +
                "<Recording>http://10.15.57.174/wav/2008/10/29/WG37100/ext37102/10.15.57.71!1~R!10292008_064002!37102!67256479!Ext!NA!1179371583!R.wav</Recording>" +
                "<Orders>有</Orders></ROOT>";
        try {
            SAXReader reader = new SAXReader();
             Document doc;
             doc = DocumentHelper.parseText(fStr);

            //Document doc = reader.read(ffile); //读取一个xml的文件
            Element root = doc.getRootElement();
            Attribute testCmd= root.attribute("test");
            System.out.println(testCmd.getName()+"-***--"+testCmd.getValue());
            Element eName = root.element("Name");
            System.out.println("节点内容*--"+eName.getTextTrim());

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

 

 

解析xml文件，xml文件如下

<?xml version="1.0" encoding="UTF-8"?>
<students>
    <student age="25">
        <name>AAA</name>
        <collage leader='班长'>xxx学校</collage>
        <telephone>13728704450</telephone>
        <notes>男，1958年出生</notes>
    </student>
    <student age="21">
        <name>BBB</name>
        <collage leader='学生'>YYY学校</collage>
        <telephone>1372sadgasg4450</telephone>
        <notes>男，1968年出生,出生地长沙</notes>
    </student>
    <student age="29">
        <name>CCC</name>
        <collage leader='班主任'>北京大学</collage>
        <telephone>13828704450</telephone>
        <notes>女，漂亮</notes>
    </student>
</students>

 

解析的代码如下

 

public void iterateWholeXML(String filename, HashMap<String, String> hm) {
        SAXReader saxReader = new SAXReader();
        try {
            Document document = saxReader.read(new File(filename));
            Element root = document.getRootElement();
            // 用于记录学生编号的变量
            int num = -1;
            // 遍历根结点（students）的所有孩子节点（肯定是student节点）
            for (Iterator iter = root.elementIterator(); iter.hasNext();) {
                Element element = (Element) iter.next();
                num++;
                // 获取person节点的age属性的值
                Attribute ageAttr = element.attribute("age");
                if (ageAttr != null) {
                    String age = ageAttr.getValue();
                    if (age != null && !age.equals("")) {
                        hm.put(element.getName() + "-" + ageAttr.getName()
                                + num, age);
                    } else {
                        hm.put(element.getName() + "-" + ageAttr.getName()
                                + num, "20");
                    }
                } else {
                    hm.put(element.getName() + "-age" + num, "20");
                }
                // 遍历student结点的所有孩子节点（即name，college，telphone，notes），并进行处理
                for (Iterator iterInner = element.elementIterator(); iterInner
                        .hasNext();) {
                    Element elementInner = (Element) iterInner.next();
                    if (elementInner.getName().equals("collage")) {
                        hm.put(elementInner.getName() + num, elementInner
                                .getText());
                        // 获取college节点的leader属性的值
                        Attribute leaderAttr = elementInner.attribute("leader");
                        if (leaderAttr != null) {
                            String leader = leaderAttr.getValue();
                            if (leader != null && !leader.equals("")) {
                                hm.put(elementInner.getName() + "-"
                                        + leaderAttr.getName() + num, leader);
                            } else {
                                hm.put(elementInner.getName() + "-"
                                        + leaderAttr.getName() + num, "leader");
                            }
                        } else {
                            hm.put(elementInner.getName() + "-leader" + num,
                                    "leader");
                        }
                    } else {
                        hm.put(elementInner.getName() + num, elementInner
                                .getText());
                    }
                }
            }
        } catch (DocumentException e) {
            e.printStackTrace();
        }
    }
