Hi

I have the following xml, and I need the XPath expression to obtain de value 
of "value" in 
/configuration/activerecord/config type="GDR.Domain.GDRBO`1, GDR.Domain"/add 
key="connection.connection_string" 

<?xml version="1.0"?>
<configuration>
	<activerecord isWeb="true">
		<config type="GDR.Domain.GDRBO`1, GDR.Domain">
			<add key="connection.driver_class" 
value="NHibernate.Driver.SqlClientDriver"/>
			<add key="dialect" value="NHibernate.Dialect.MsSql2000Dialect"/>
			<add key="connection.provider" 
value="NHibernate.Connection.DriverConnectionProvider"/>
			<add key="connection.connection_string" value="Data 
Source=pcsql\sql2k;User Id=sa;Password=gg;initial catalog=GDR"/>
		</config>
		<config type="GDR.Domain.rrhh.rrhhBO`1, GDR.Domain.rrhh">
			<add key="connection.driver_class" 
value="NHibernate.Driver.SqlClientDriver"/>
			<add key="dialect" value="NHibernate.Dialect.MsSql2000Dialect"/>
			<add key="connection.provider" 
value="NHibernate.Connection.DriverConnectionProvider"/>
			<add key="connection.connection_string" value="Data 
Source=pcsql\sql2k;Initial Catalog=rrhh;User Id=sa;Password=gg"/>
		</config>
		<config type="GDR.Domain.Personal.PersonalBO`1, GDR.Domain.Personal">
			<add key="connection.driver_class" 
value="NHibernate.Driver.SqlClientDriver"/>
			<add key="dialect" value="NHibernate.Dialect.MsSql2000Dialect"/>
			<add key="connection.provider" 
value="NHibernate.Connection.DriverConnectionProvider"/>
			<add key="connection.connection_string" value="Data 
Source=pcsql\sql2k;Initial Catalog=db_IdPersonal;User Id=sa;Password=gg"/>
		</config>
