Hello!
I am new to XML and XPath (I am reading material on XPath, and know some basics but it will take me some time). I need
to parse some XML statements, and build some simple data structures using XML::XPath. I have never used this
module, so I have a lot to learn about it too. I have downloaded this module and can use it.

Could some one help me with some sample code to get started?

My XML file looks like this (a portion of it): 
test.xml

- <AnnualWeatherRecord>
- <DailyWeatherRecord>
  <date>1-1-2004</date> 
- <temperature>
  <maxdrybulb unit="degrees-centigrade" number="33.95" /> 
  <mindrybulb unit="degrees-centigrade" number="30.95" /> 
  <maxwetbulb unit="degrees-centigrade" number="33.53" /> 
  <minwetbulb unit="degrees-centigrade" number="30.53" /> 
  </temperature>
  <totalrainfall unit="mm" number="0.5" /> 
  </DailyWeatherRecord>
- <DailyWeatherRecord>
  <date>2-1-2004</date> 
- <temperature>
  <maxdrybulb unit="degrees-centigrade" number="23.34" /> 
  <mindrybulb unit="degrees-centigrade" number="23.20" /> 
  <maxwetbulb unit="degrees-centigrade" number="23.14" /> 
  <minwetbulb unit="degrees-centigrade" number="20.14" /> 
  </temperature>
  <totalrainfall unit="mm" number="0" /> 
  </DailyWeatherRecord>
- <DailyWeatherRecord>
  <date>1-2-2004</date> 
- <temperature>
  <maxdrybulb unit="degrees-centigrade" number="44.25" /> 
  <mindrybulb unit="degrees-centigrade" number="39.25" /> 
  <maxwetbulb unit="degrees-centigrade" number="33.53" /> 
  <minwetbulb unit="degrees-centigrade" number="30.53" /> 
  </temperature>
  <totalrainfall unit="mm" number="0.5" /> 
  </DailyWeatherRecord>
- <DailyWeatherRecord>
  <date>2-2-2004</date> 
- <temperature>
  <maxdrybulb unit="degrees-centigrade" number="50.25" /> 
  <mindrybulb unit="degrees-centigrade" number="49.25" /> 
  <maxwetbulb unit="degrees-centigrade" number="23.14" /> 
  <minwetbulb unit="degrees-centigrade" number="20.14" /> 
  </temperature>
  <totalrainfall unit="mm" number="0" /> 
  </DailyWeatherRecord>
- <MonthlyWeatherRecord>
  <date>1-2004</date> 
- <temperature>
  <maxdrybulb unit="degrees-centigrade" number="33.95" /> 
  <mindrybulb unit="degrees-centigrade" number="23.20" /> 
  <avgdrybulb unit="degrees-centigrade" number="33.95" /> 
  </temperature>
  </MonthlyWeatherRecord>
- <MonthlyWeatherRecord>
  <date>2-2004</date> 
- <temperature>
  <maxdrybulb unit="degrees-centigrade" number="50.25" /> 
  <mindrybulb unit="degrees-centigrade" number="39.25" /> 
  <avgdrybulb unit="degrees-centigrade" number="44.25" /> 
  </temperature>
  </MonthlyWeatherRecord>
  </AnnualWeatherRecord>

Using XML::XPath, I need to build a subroutine that does this:

Accepts a date as a parameter, and searches the xml file for the node with that particular date. It extracts the
value of the maxdrybulb attribute, and builds an array which stores the date and the max dry bulb temperature.

For e.g. a sample array say @array would look like: 
  @array[0]=1-1-2004
  @array[1]=33.95

I need another subroutine which stores the date and the value of the mindrybulb attribute, but the code would
mostly be the same I guess.

Please help!
Any help would be appreciated.

Thanks,
perl_seeker:)
