Question

我有一个包含多个host元素的XML文件。请参阅下面的示例。

在我的网络中，有几台计算机运行Linux，Microsoft和Apple操作系统。我只对显示“Linux”系统感兴趣。我已经能够使用下面的XPath，但这仅适用于一个属性：IP或可用的MAC地址。

//host[status[@state='up'] and os[osmatch/osclass[@osfamily='Linux']]]/address[@addrtype='ipv4' or @addrtype='mac']/@addr

除IP地址外，我还需要显示hostname的名称和协议（服务名称（SSH / Telnet），打开/关闭状态和端口号。我有以下内容XPath的：

//host[status[@state='up'] and os[osmatch/osclass[@osfamily='Linux']]]/hostnames/hostname[@name]

//host[status[@state='up'] and os[osmatch/osclass[@osfamily='Linux']]]/os/portused/@portid

//host[status[@state='up'] and os[osmatch/osclass[@osfamily='Linux']]]/os/portused/@open

我需要结合所有这些XPath来生成以下输出：

Hosts running Linux
------------------------- 
Hostname: ubuntu.gateway.2wire.net
Host IP: 192.168.1.158 
Protocols: SSH (open/22), Telnet (closed/23)

无论如何，我可以将所有XPath合并到一个Xpath中吗？

Answer 1

我会使用XSLT，它可以一次性完成 - 拉出你想要的XPath并显示它旁边的标签。

将多个XPath组合到一个XPath中
