Shell SCript to read XML tags and the data within that tag

[SmilePlease]

Hi unix Gurus,

I am really new to Unix Scripting. Please help me to create a shell script which reads the xml file and from that i need to fetch a particular information.

For example
<SOURCE BUSINESSNAME ="" DATABASETYPE ="Teradata" DBDNAME ="DWPROD3" DESCRIPTION ="" NAME ="ACTRL_BNFT_KEY_DMN" OBJECTVERSION ="1" OWNERNAME ="COC_V20_ETL_APPL" VERSIONNUMBER ="1">
<SOURCEFIELD BUSINESSNAME ="" DATATYPE ="varchar" DESCRIPTION ="" FIELDNUMBER ="1" FIELDPROPERTY ="0" FIELDTYPE ="ELEMITEM" HIDDEN ="NO" </SOURCE>

From the above xml file , I have to read the xml file and get the source name from the file as the below output.

SOURCE ->ACTRL_BNFT_KEY_DMN.

Please help me UNIX Gurus.
