How Navigate XML with augeas xml

I have a very strange xml file that i need to update using augeas. 

<root>
    <node name="Client">
        <node name="Attributes">
            <info>
                <test>
                    <entry><key>colour</key><value type="string">blue</value></entry>
                </test>
            </info>
        </node>
    </node>
    <node name="Network">
        <node name="Server">
            <info>
                <test>
                    <entry><key>transport</key><value type="string">internet</value></entry>
                    <entry><key>ipAddr</key><value type="string">125.125.125.142</value></entry>
                    <entry><key>portNo</key><value type="string">1234</value></entry>
                    <entry><key>protocolType</key><value type="string">tcp</value></entry>
                </test>
            </info>
        </node>
    </node>
</root>

I need to update the element "value" which is just after the element "key" which contains the text ipAddr.

Solution

  • Based on your description of the node you want to update, here's a suggestion:

    set /files/path/to/your/file.xml//entry[key/#text="ipAddr"]/value/#text "255.255.255.0"

    This selects the entry node at any level in the file, which has a key/#text subnode with value ipAddr and then it updates its value/#text subnode to have value 255.255.255.0.
