Description

Hi,

I find out that there is missing very usefull functionality for
org.apache.commons.configuration.HierarchicalConfiguration.

For instance, I have XML like below:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
<Service name="contract.funds" class="my.MyClass">
<ServiceParameters>
<Param key="generate.request" value="true" />
<Param key="request.xml.name"
value="LifeFunds_REQ.xml" />
<Param key="transform.response" value="true" />
<Param key="reply.xml.name"
value="dummy/LifeFunds_REP.xml" />
<Param key="digester-rules.xml"
value="LifeFunds_rules.xml" />
</ServiceParameters>
</Service>

<Service name="contract.servicing.agents" class="my.MyClass">
<ServiceParameters>
<Param key="generate.request" value="true" />
<Param key="request.xml.name"
value="LifeServicingAgents_REQ.xml" />
<Param key="transform.response" value="true" />
<Param key="reply.xml.name"
value="dummy/LifeServicingAgents_REP.xml" />
<Param key="digester-rules.xml"
value="LifeServicingAgents_rules.xml" />
</ServiceParameters>
</Service>

<Service name="contract.additional.info" class="my.MyClass">
<ServiceParameters>
<Param key="generate.request" value="true" />
<Param key="request.xml.name"
value="LifeAdditionalInfo_REQ.xml" />
<Param key="transform.response" value="true" />
<Param key="reply.xml.name"
value="dummy/LifeAdditionalInfo_REP.xml" />
<Param key="digester-rules.xml"
value="LifeAdditionalInfo_rules.xml" />
</ServiceParameters>
</Service>
</Configuration>

From the application I would like to go directly to the configuration of
service with name: "contract.funds" instead of reading whole hierarhi and check
if the name is equals "contract.funds" I prefer to get its parameters like this:

config.getProperty("Service[@name='contract.funds']").ServiceParameters.Param)

instead of calling in a loop:

for(int i=0;;i++){
if(config.getProperty("Service("i")[@name]").equals("contract.funds"))

{ // DO SOMETHING }

}

So in a simple words - it would be very helpfull if there will be full
supoorted the XML Path Language (XPath) during requesting properties.

Best regards
Rafal
