将键/值添加到 XML 文件

Question

我有以下文件：

<?xml version="1.0" encoding="UTF-8"?>
<confluence-configuration>
  <setupStep>complete</setupStep>
  <setupType>custom</setupType>
  <buildNumber>8506</buildNumber>
  <properties>
    <property name="attachments.dir">${confluenceHome}/attachments</property>
    <property name="confluence.setup.server.id">BN4J-RBSE-6ZPZ-GB4G</property>
    <property name="confluence.webapp.context.path"></property>
    <property name="hibernate.connection.datasource">java:comp/env/jdbc/confluence</property>
    <property name="hibernate.database.lower_non_ascii_supported">true</property>
    <property name="hibernate.dialect">com.atlassian.confluence.impl.hibernate.dialect.PostgreSQLDialect</property>
    <property name="hibernate.setup">true</property>
    <property name="lucene.index.dir">${localHome}/index</property>
    <property name="synchrony.encryption.disabled">true</property>
    <property name="synchrony.proxy.enabled">true</property>
    <property name="webwork.multipart.saveDir">${localHome}/temp</property>
  </properties>
</confluence-configuration>

添加如下所示的键/值对的最佳方法是什么？

    <property name="hibernate.c3p0.acquire_increment">1</property>
    <property name="hibernate.c3p0.idle_test_period">100</property>
    <property name="hibernate.c3p0.max_size">60</property>
    <property name="hibernate.c3p0.max_statements">0</property>
    <property name="hibernate.c3p0.min_size">20</property>
    <property name="hibernate.c3p0.timeout">30</property>
    <property name="hibernate.c3p0.validate">true</property>

我希望与 xmlstarlet 一起这样做。

编辑 1：我试过了：

xmlstarlet edit --update "/confluence-configuration/properties/property[@name='hibernate.c3p0.acquire_increment']/@name" --value "1" confluence.cfg.xml

但这弄乱了我的 xml 文件

编辑 2：显然这与 <property name="confluence.webapp.context.path"></property>
我现在有一个有效的更新命令：

xmlstarlet ed --update "/confluence-configuration/properties/property[@name='hibernate.c3p0.acquire_increment']" --value "5" confluence.cfg.xml

但是插入怎么样？

谢谢！

可能不是最好的方法，但我是这样解决的；

declare -A xmlArray
  xmlArray[hibernate.c3p0.acquire_increment]=1
  xmlArray[hibernate.c3p0.idle_test_period]=100
  xmlArray[hibernate.c3p0.max_size]=${CONFLUENCE_MAX_DB_CONNECTIONS}
  xmlArray[hibernate.c3p0.max_statements]=0
  xmlArray[hibernate.c3p0.min_size]=20
  xmlArray[hibernate.c3p0.timeout]=30
  xmlArray[hibernate.c3p0.validate]=true
  xmlArray[hibernate.connection.driver_class]=org.postgresql.Driver
  xmlArray[hibernate.connection.isolation]=2
  xmlArray[hibernate.connection.password]=${CONFLUENCE_DATABASE_PASSWORD}
  xmlArray[hibernate.connection.url]=${CONFLUENCE_DATABASE_URL}
  xmlArray[hibernate.connection.username]=${CONFLUENCE_DATABASE_USERNAME}

  xmlstarlet ed --inplace -d "/confluence-configuration/properties/property[@name='hibernate.connection.datasource']" ${CONFLUENCE_HOME}/confluence.cfg.xml

  for KEY in "${!xmlArray[@]}"; do
    if [ -n "$(xmlstarlet sel -T -t -v "/confluence-configuration/properties/property[@name='$KEY']/@name" ${CONFLUENCE_HOME}/confluence.cfg.xml)" ]; then
      xmlstarlet ed --inplace --update "/confluence-configuration/properties/property[@name='$KEY']" --value "${xmlArray[$KEY]}" ${CONFLUENCE_HOME}/confluence.cfg.xml;
    else
      xmlstarlet edit -L --subnode "/confluence-configuration/properties" --type elem -n property --value "${xmlArray[$KEY]}" --insert "/confluence-configuration/properties/property[last()]" --type attr -n name --value "$KEY" ${CONFLUENCE_HOME}/confluence.cfg.xml;
    fi
  done

Add key / value to XML file
