Hi, I am using a XML file in server location which contains some attributes and value.I just want to replace the attribute value inside the tag keeping the complete line and xml file intact. I am looking for Regular expression which can search for attribute name and replace the attribute value with the provided one. Please find below property details.

<server>
<mbean code="com.xyz.domain.wsmq.WSMQConnectionFactory"
name="xyz.qps:service=MQQueueConnectionFactory">
<attribute name="QueueManagerName">QMSTR01</attribute>
<attribute name="HostName">xx.yy.zz.ww</attribute>
<attribute name="Channel">channel01</attribute>
<depends>jboss:service=Naming</depends>
</mbean>
</server>

I found one regular expression as mentioned below using sed from below link , but it is throwing throwing error.
