如何使用java解析器从nmap XML字符串（IP、端口）获取信息

我对编码是新手，我试图从NMAP4j生成的XML字符串中获取信息

<?xml version="1.0"?>
<?xml-stylesheet href="file:///usr/local/share/nmap/nmap.xsl" type="text/xsl"?>
<!-- Nmap 6.01 scan initiated Mon Jan 14 13:56:47 2013 as: /usr/local/bin/nmap -&#45;datadir /usr/local/share/nmap -T4 -oX - 192.168.1.1 -->

</runstats>
</nmaprun>

但我无法找到一个解决方案，即拥有对象并操纵这些对象以获取所有信息

请帮我用一个简单的代码示例让所有人都能理解

您是否正在尝试解析现有文件？如果是：

OnePassParser opp = new OnePassParser() ;
NMapRun nmapRun = opp.parse( fileName, OnePassParser.FILE_NAME_INPUT ) ;

没有字符串输入，我找不到如何获取对象或信息。我在阅读文档后找到了一个解决方案，这是为第一台主机OnePassParser opp=new OnePassParser（）获取供应商的示例；NMapRun nmapRun1=opp.parse（NMapRun，OnePassParser.STRING\u输入）；ArrayList hosts=nmapRun1.getHosts（）；System.out.println（hosts.get（0.getAddress（）.getVendor（））；您好-您能够获取其他XML标记的内容吗？e、 g.使用“-script=ssl cert ssl”标志的结果

OnePassParser opp = new OnePassParser() ;
NMapRun nmapRun = opp.parse( fileName, OnePassParser.FILE_NAME_INPUT ) ;
