but that doesnt work. I cant figure out how to change the voltage based on the value of Name.

"doesn't work" isn't diagnostic ... :)

but, even in xpath, you can't make syntax up :) grab xpather.pl and see what it spits out 

/Settings/Channels/Channel[4]

# posy
/Settings[1]/Channels[1]/Channel[4]

# star
/*[ local-name() = "Settings"
    and position() = 1
  ]

/*[ local-name() = "Channels"
    and position() = 1
  ]

/*[ local-name() = "Channel"
    and @Name = "L360"
    and @Voltage = "120"
    and @Test = "1"
  ]


# rats
/Settings[1]
 /Channels[1]
 /*[ name() = "Channel" and position() = 4 and @Name = "L360" and @Vol
+tage = "120" and @Test = "1" ]

So next step is adjust your xpath to be valid :)
