使用awk编辑xml文件

Question

我想更新acceptcount＆amp;的连接器标签属性遗嘱执行人以下列方式。

        <Connector acceptCount="1000" 
                   address="${ajp.listen.address}"
                   connectionTimeout="20000"
                   executor="tomcatThreadPoolupdated1" 
                   maxKeepAliveRequests="15" 
                   port="${ajp.http.port}"  
                   protocol="org.apache.coyote.ajp.AjpProtocol"/>
        <Connector acceptCount="20000" 
                   address="${bio.listen.address}"
                   connectionTimeout="20000"
                   executor="tomcatThreadPoolupdated2"
                   maxKeepAliveRequests="15" 
                   port="${bio.http.port}" 
                   protocol="org.apache.coyote.http11.Http11Protocol" 
                   redirectPort="${bio.https.port}"/>

这是我的xml。 如果您使用awk提供解决方案，请解释解决方案。

    <?xml version="1.0"?>
    <Server port="${base.shutdown.port}" shutdown="SHUTDOWN">
      <Service name="Catalina">
        <Connector acceptCount="300" 
                   address="${ajp.listen.address}"
                   connectionTimeout="20000"
                   executor="tomcatThreadPool" 
                   maxKeepAliveRequests="15" 
                   port="${ajp.http.port}"  
                   protocol="org.apache.coyote.ajp.AjpProtocol"/>
        <Connector acceptCount="200" 
                   address="${bio.listen.address}"
                   connectionTimeout="20000"
                   executor="tomcatThreadPool111"
                   maxKeepAliveRequests="15" 
                   port="${bio.http.port}" 
                   protocol="org.apache.coyote.http11.Http11Protocol" 
                   redirectPort="${bio.https.port}"/>
      </Service>
    </Server>
