我想在我的 python 代码中使用 xpath 函数，所以它也需要命名空间

【问题讨论】：

xmlns标签表示xml命名空间
“我想在我的 python 代码中使用 xpath 函数”- 好的。实际问题是什么？你的 Python 代码在哪里？请注意，只有 connect 名称空间前缀实际用在 XML 文档中。

标签： python xml

【解决方案1】：

此 XML 的名称空间值为：

xmlns:cdesc="exa:com.exalead.mercury.component.config.descriptor"
xmlns:connect="exa:com.exalead.mercury.mami.connect.v10"
xmlns:bee="exa:exa.bee"
xmlns:config="exa:exa.bee.config"

【解决方案2】：

XML 格式如下：

<?xml version="1.0" encoding="utf-8"?>
<connect:ConnectorsStatus xmlns:cdesc="exa:com.exalead.mercury.component.config.descriptor" xmlns:connect="exa:com.exalead.mercury.mami.connect.v10" xmlns:bee="exa:exa.bee" xmlns:config="exa:exa.bee.config">
  <connect:ConnectorStatus connectorName="quasar_vpminstance" managed="true" connectorServer="java0" status="idle" classId="com.exalead.papi.connectors.jdbc.DatabaseConnector" runtime="java" papiServerType="consolidationServer">
  <connect:PerBuildGroupStatus buildGroup="bg_search" activeDocumentsCount="0" totalAdds="0" totalReplaces="0" totalDeletes="0" totalFailedDeletes="0" totalPartialUpdates="0" totalIndexedDocuments="0" />
  <connect:PerBuildGroupStatus buildGroup="bg_ndt_search" activeDocumentsCount="0" totalAdds="0" totalReplaces="0" totalDeletes="0" totalFailedDeletes="0" totalPartialUpdates="0" totalIndexedDocuments="0" />
  <connect:PerConsolidationServerStatus consolidationServer="cs0" totalAdds="0" totalReplaces="0" totalDeletes="0" totalFailedDeletes="0" totalConsolidatedDocuments="981214" />
  <connect:previousScan>
    <connect:ScanStatus aborted="false" time="1669" startTime="1676960680503" endTime="1676960682172" scannedObjects="86" pushedObjects="86" deletedObjects="0" scanRetries="0">
      <connect:specificMeasures />
    </connect:ScanStatus>
  </connect:previousScan>be</connect:ConnectorStatus>
</connect:ConnectorsStatus>

然后你用xml.etree.ElementTree解析它：

import xml.etree.ElementTree as ET

tree = ET.parse("connect.xml")
root = tree.getroot()

for elem in root.iter():
    print(elem.tag)

输出：

{exa:com.exalead.mercury.mami.connect.v10}ConnectorsStatus
{exa:com.exalead.mercury.mami.connect.v10}ConnectorStatus
{exa:com.exalead.mercury.mami.connect.v10}PerBuildGroupStatus
{exa:com.exalead.mercury.mami.connect.v10}PerBuildGroupStatus
{exa:com.exalead.mercury.mami.connect.v10}PerConsolidationServerStatus
{exa:com.exalead.mercury.mami.connect.v10}previousScan
{exa:com.exalead.mercury.mami.connect.v10}ScanStatus
{exa:com.exalead.mercury.mami.connect.v10}specificMeasures

所以你搜索的相关命名空间是：{exa:com.exalead.mercury.mami.connect.v10}
