xmllint usage - having a hard time getting xml attributes

I'm in the process of retreiving some data from a xml file, it is actually a SSIS package file (dtsx). I've read about using xmllint, however I'm having a hard time retrieving what I want. I'd like to ask some helps from folks here. This is what my xml looks like: 8 I'm looking to get the value "**8**" out of this line 8 so, what I did was to issue a command xmllint --xpath "//*[local-name()='Executable']/*[local-ame()='Property']/text()" HardestNestedWorkflow2_latest.xml .. and it was good, I was able to extract the value "8" Now, I wanted to extract the value

Data Source=ADMIN-8DF005D47;Initial Catalog=AdventureWorks;Provider=SQLNCLI11;Integrated Security=SSPI;Application Name=SSIS-HardestNestedWorkflow2-{A32A68DF-3D53-4057-AF80-1B8D524F82BC}ADMIN-8DF005D47.AdventureWorks;Auto Translate=False;

I issued this statement xmllint --xpath "//*[local-name()='Executable']/*[local-name()='ConnectionManagers']/*[local-name()='ConnectionManager']/*[local-name()='ObjectData']/*[local-name()='ConnectionManager']" HardestNestedWorkflow2_latest.xml and it returned this how can I omit the tags DTS:ConnectionManager DTS:ConnectionString? I'm sorry I'm not much knowledgeable on using xmllint. Thanks in Advance
