Re: Is DOM vs SAX a red herring?

Larry,

I'll probably regret this, but I can't resist the opportunity to stir the pot. Your example (see below) seems contrary to your position that information such as OSPF interface metrics and dead intervals should be attributes, not elements.

Keith,

To represent the transaction in multiple parts the target has to be identified.
We have used XPath expressions for this purpose as in the following example:

<transaction id="29">
       <deleteRequest opId="2" select="/root/configuration/protocol/ospf/area[@id='0']" />
       <deleteRequest opId="1" select="/root/configuration/protocol/ospf/area[@id='3']" />
       <addRequest opId="3" select="/root/configuration/protocol/ospf">
           <area id="4">
               <interface id="ge-2/2">
                   <authentication-key>
                       <keyname>gargoyle</keyname>
                       <key-id>3</key-id>
                   </authentication-key>
                   <metric>1</metric>
                   <hello-interval>10</hello-interval>
                   <dead-interval>40</dead-interval>
                   <retransmit-interval>10</retransmit-interval>
                   <transit-delay>5</transit-delay>
               </interface>
           </area>
       </addRequest>
       <addRequest opId="4" select="/root/configuration/protocol/ospf/area[@id='2']/interface[@id='ge-1/5']">
           <dead-interval>40</dead-interval>
       </addRequest>
       <addRequest opId="5" select="/root/configuration/protocol/is-is">
           <area id="5"></area>
       </addRequest>
       <addRequest opId="6" select="/root/configuration/protocol/ospf/area[@id='1']">
           <label-switched-path id="to-SFO">
               <metric>15</metric>
           </label-switched-path>
       </addRequest>
       <replaceRequest opId="7" select="/root/configuration/protocol/ospf/area[@id='6']/label-switched-path[@id='to-SFO']">
           <metric>20</metric>
       </replaceRequest>
   </transaction>
