与两个单独的文本匹配的正则表达式，也忽略中间的所有内容

Question

我是您典型的网络专家，对这种东西我是完全陌生的。我会尽力解释我需要什么帮助。

我正在使用Cisco Prime查找包含两个单独字符串的所有设备。

第一个是-

device-sensor filter-list dhcp list DHCP_LIST_NAME

第二个是-

ip address-helper 1.1.1.1 

这是我最后尝试的方法。

(device-sensor filter-list dhcp list DHCP_LIST_NAME)|(ip address-helper 1.1.1.1)

理想情况下，我想匹配第一个字符串，忽略任何空格和之间的任何字符，然后匹配第二个字符串。

我已经通过Regex101运行了它，它似乎可以工作，但是似乎有一种更好甚至更干净的方法。从目前为止我所读的内容中，竖线字符匹配一件事或另一件事。我需要将其匹配，以便我可以告诉Cisco Prime提出违规并进行修复。

编辑：添加了示例配置。

device-sensor filter-list cdp list CDP_LIST_NAME
*device-sensor filter-list dhcp list DHCP_LIST_NAME*
device-sensor filter-list lldp list LLDP_LIST_NAME
device-sensor filter-spec dhcp include list DHCP_LIST_NAME
device-sensor filter-spec lldp include list LLDP_LIST_NAME
device-sensor filter-spec cdp include list CDP_LIST_NAME
device-sensor accounting
device-sensor notify all-changes

Answer 1

您可以使用以下模式：

/(device-sensor filter-list dhcp list DHCP_LIST_NAME).*(ip helper-address 1\.1\.1\.1)/igm

这将与第一个词匹配，然后与下一个词匹配。我们需要逃脱。在IP地址中。由于该模式在方括号中包含术语，因此将创建两个捕获组。这些实际上不是必需的，但是包含在演示中，您可以返回匹配的组。

下面的代码段：

const data = 'device-sensor filter-list cdp list CDP_LIST_NAME device-sensor filter-list dhcp list DHCP_LIST_NAME device-sensor filter-list lldp list LLDP_LIST_NAME device-sensor filter-spec dhcp include list DHCP_LIST_NAME device-sensor filter-spec lldp include list LLDP_LIST_NAME device-sensor filter-spec cdp include list CDP_LIST_NAME device-sensor accounting device-sensor notify all-changes ! ! interface Vlan1 description PRINTERs ip address 2.2.2.2 255.255.255.0 ip helper-address 10.10.10.1 ip helper-address 10.10.10.2 ip helper-address 1.1.1.1 no ip redirects no ip unreachables';

let match = /(device-sensor filter-list dhcp list DHCP_LIST_NAME).*(ip helper-address 1\.1\.1\.1)/igm.test(data);

console.log(match);

使用正则表达式搜索固定长度的字符串可能有点过分。这是JavaScript，但是大多数语言都允许您在另一个字符串中搜索子字符串，并返回找到匹配项的索引，或者如果找不到子字符串则返回一些错误指示：

const text = 'device-sensor filter-list cdp list CDP_LIST_NAME device-sensor filter-list dhcp list DHCP_LIST_NAME\ndevice-sensor filter-list lldp list LLDP_LIST_NAME device-sensor filter-spec dhcp include list DHCP_LIST_NAME device-sensor filter-spec lldp include list LLDP_LIST_NAME device-sensor filter-spec cdp include list CDP_LIST_NAME device-sensor accounting device-sensor notify all-changes ! ! interface Vlan1 description PRINTERs ip address 2.2.2.2 255.255.255.0 ip helper-address 10.10.10.1 ip helper-address 10.10.10.2 ip helper-address 1.1.1.1 no ip redirects no ip unreachables';

if (text.indexOf('device-sensor filter-list dhcp list DHCP_LIST_NAME') != -1 &&
    text.indexOf('ip helper-address 1.1.1.1') != -1) {
    console.log('Found it')
}

在Python中：

text = """device-sensor filter-list cdp list CDP_LIST_NAME
*device-sensor filter-list dhcp list DHCP_LIST_NAME*
device-sensor filter-list lldp list LLDP_LIST_NAME
device-sensor filter-spec dhcp include list DHCP_LIST_NAME
device-sensor filter-spec lldp include list LLDP_LIST_NAME
device-sensor filter-spec cdp include list CDP_LIST_NAME
