如何提取xml数据并打印调试消息
如何提取xml数据并打印调试消息
提问于 2019-10-30 18:36:45
我试图通过xpath提取两个元素(l2-mac-address和l2-mac-logical-interface)，并将它们打印为“mac地址:接口”。
XML：
<l2ald-rtb-macdb>
<l2ald-mac-entry junos:style="brief-rtb">
<l2-mac-routing-instance>lab-ppp</l2-mac-routing-instance>
<l2-mac-bridging-domain>__lab-ppp__</l2-mac-bridging-domain>
<l2-bridge-vlan>none</l2-bridge-vlan>
<l2-mac-entry>
<l2-mac-address>28:c0:da:6c:43:38</l2-mac-address>
<l2-mac-flags>D</l2-mac-flags>
<l2-mac-logical-interface>ge-11/2/2.698</l2-mac-logical-interface>
</l2-mac-entry>
<l2-mac-entry>
<l2-mac-address>60:03:47:07:c8:96</l2-mac-address>
<l2-mac-flags>D</l2-mac-flags>
<l2-mac-logical-interface>xe-70/0/0.698</l2-mac-logical-interface>
</l2-mac-entry>
<l2-mac-entry>
<l2-mac-address>60:03:47:09:6b:51</l2-mac-address>
<l2-mac-flags>D</l2-mac-flags>
<l2-mac-logical-interface>xe-70/0/0.698</l2-mac-logical-interface>
</l2-mac-entry>
<l2-mac-entry>
<l2-mac-address>60:03:47:17:fb:c7</l2-mac-address>
<l2-mac-flags>D</l2-mac-flags>
<l2-mac-logical-interface>xe-70/0/1.698</l2-mac-logical-interface>
</l2-mac-entry>
</l2ald-mac-entry>
</l2ald-rtb-macdb>剧本：
tasks:
- name: RUN RPC Command
juniper_junos_rpc:
rpcs:
- get-vpls-mac-table
kwargs:
instance: lab-ppp
provider: "{{ credentials }}"
register: vpls_info
- name: query mac info
xml:
xmlstring: "{{ vpls_info.stdout }}"
xpath: //l2-mac-entry/l2-mac-address | //l2-mac-entry/l2-mac-logical-interface
content: text
register: vpls_macs
- name: show results
debug:
var: vpls_macs.matches目前的结果：
"vpls_macs.matches": [
{
"l2-mac-address": "28:c0:da:6c:43:38"
},
{
"l2-mac-logical-interface": "ge-11/2/2.698"
},
{
"l2-mac-address": "60:03:47:07:c8:96"
},
{
"l2-mac-logical-interface": "xe-70/0/0.698"
}
]如何获得mac地址和它的接口，以显示在同一个debug: msg中？
编辑：
如何将mac和接口字符串列表放入变量？我试着把它添加到剧本中：
- name: Build List
set_fact:
mac_list: "{{ mac_list|default([]) }} + [ '{{item[0]['l2-mac-address'] }}: {{ item[1]['l2-mac-logical-interface'] }}' ]"
loop: "{{ vpls_mac_address.matches | zip(vpls_mac_interface.matches) | list }}"
- name: Show Results
debug:
var: mac_list但是只将最后一个mac和接口添加到变量中：
TASK [Show Results] *************
ok: [lab960.ftc] => {
"mac_list": [
"60:03:47:17:fb:c7: xe-70/0/1.698"
]

我稍微修改了你的剧本，引入了不同的任务来提取mac地址和界面。通过这种方式，您将得到两个列表，它们可以被压缩以获得所需的输出。
tasks:
- name: RUN RPC Command
juniper_junos_rpc:
rpcs:
- get-vpls-mac-table
kwargs:
instance: lab-ppp
provider: "{{ credentials }}"
register: vpls_info
- name: query mac address info
xml:
xmlstring: "{{ vpls_info.stdout }}"
xpath: //l2-mac-entry/l2-mac-address
content: text
register: vpls_mac_address
- name: query mac interface info
xml:
xmlstring: "{{ vpls_info.stdout }}"
xpath: //l2-mac-entry/l2-mac-logical-interface
content: text
register: vpls_mac_interface
- name: debug
debug:
msg: "{{ item[0]['l2-mac-address'] }}: {{ item[1]['l2-mac-logical-interface'] }}"
loop: "{{ vpls_mac_address.matches | zip(vpls_mac_interface.matches) | list }}"页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
