优点:
高效、简单、易用的Xml解析器。
学习时间,分分钟。
支持中文标签名与属性名,支持下划线,减号等分隔符。
解析速度超过,查找速度超快,支持格式化。
缺点:不支持XmlSchema,DTD校验。
Maven引用坐标:
<dependency><groupId>org.tinygroup</groupId><artifactId>org.tinygroup.xmlparser</artifactId><version>0.1.0-SNAPSHOT</version></dependency>解析下面xml
<?xml version="1.0"?><students> <student> <name>John</name> <grade>B</grade> <age>12</age> </student> <student> <name>Mary</name> <grade>A</grade> <age>11</age> </student> <student> <name>Simon</name> <grade>A</grade> <age>18</age> </student></students>示例代码:
public class TestXmlParser { public static void main(String[] args) throws Throwable { File file = new File("E:/test/students.xml "); XmlStringParser parser = new XmlStringParser(); XmlDocument document = parser.parse(IOUtils.readFromInputStream( new FileInputStream(file), "utf-8")); printStudents(document.getRoot()); } private static void printStudents(XmlNode studentsNode) { for(XmlNode studentNode:studentsNode.getSubNodes("student")){ printStuent(studentNode); } } private static void printStuent(XmlNode studentNode) { printSubTagByName(studentNode,"name"); printSubTagByName(studentNode,"grade"); printSubTagByName(studentNode,"age"); } private static void printSubTagByName(XmlNode studentNode,String tagName) { System.out.println( studentNode.getSubNode(tagName).getContent()); }}格式化示例:
XmlDocument doc;doc = new XmlStringParser() .parse("aaa");XmlFormater f = new XmlFormater();System.out.println(f.format(doc));运行结果:
aaa性能测试:
构建下面的节点规模:
HtmlNode node = null;public NameFilterTest() {node = new HtmlNode("root");for (int i = 0; i < 60; i++) {HtmlNode a = node.addNode(new HtmlNode("a" + i));for (int j = 0; j < 60; j++) {HtmlNode b = a.addNode(new HtmlNode("b" + j));for (int k = 0; k < 60; k++) {b.addNode(new HtmlNode("c" + k));}}}}也就是节点数60+60*60+60*60*60个节点数时,进行下面的查找:
long t21 = System.currentTimeMillis();FastNameFilter fast = new FastNameFilter(node);long t22 = System.currentTimeMillis();System.out.println("fast初始化用时" + (t22 - t21));long t1 = System.currentTimeMillis();String nodeName = null;for (int x = 0; x < 10000; x++) {nodeName = fast.findNode("b6").toString();}// System.out.println(nodeName);long t2 = System.currentTimeMillis();System.out.println("FastNameFilter用时" + (t2 - t1));运行结果:
fast初始化用时130FastNameFilter用时450也就是说在219661个节点中,查找指定节点10000次,只用时450ms。
