I am trying to extract the temperature in “73.2”. I can get the data from but I can’t figure out how to get data from from . How do I get to to get the info I want?

thanks!

(*

<?xml version='1.0' encoding='UTF-8'?> My Device 01/01/1970 00:06:13 Fahrenheit 1T 73.2 85 10 0 0

set XMLfile to "Users:mcp:desktop:inwork:xmlfeed.xml"

tell application "System Events"
	tell XML element 1 of contents of XML file XMLfile
		set typeText to (value of (XML elements whose name is "currentConditions")) as string
		set nameText to (value of (XML elements whose name is "readingDateTime")) as string
		set nameText to (value of (XML elements whose name is "tempUnits")) as string
	end tell
end tell

Just follow the path…

value of xml element "currentReading" of xml element "condition" of xml element "port" of xml element "ports" of xml element "currentCondiions"

If there are more ports and more conditions on each port you should fetch it by it’s attribute values


set XMLfile to "Users:mcp:desktop:inwork:xmlfeed.xml"
set currentReading to missing value

tell application "System Events"
	set XMLRoot to contents of XML file XMLfile
	repeat with thisPort in XML elements of (XML element "ports" of XML element "currentConditions" of XMLRoot)
		if value of XML attribute "name" of thisPort = "Port 1" then
			repeat with thisCondition in XML elements of thisPort
				if value of XML attribute "type" of thisCondition = "temperature" then
					set currentReading to value of XML element "currentReading" of thisCondition
					exit repeat
				end if
			end repeat
			exit repeat
		end if
	end repeat
end tell

return currentReading

Thanks for your reply but using your advise to “Just follow the path” I can’t get this to work

set XMLfile to "Users:mcppvb:desktop:inwork:xmlfeed.xml"

tell application "System Events"
	
	value of (XML element "currentReading" of XML element "condition" of XML element "port" of XML element "ports" of XML element "currentCondiions") of XMLfile
	
end tell

Hi,

a literal string path is not a XML file, try this


set XMLfilePath to "Users:mcppvb:desktop:inwork:xmlfeed.xml"

tell application "System Events"
	set XMLfile to XML file XMLfilePath
	value of (XML element "currentReading" of XML element "condition" of XML element "port" of XML element "ports" of XML element "currentCondiions") of contents of XMLfile
end tell

Note: the root element of a XML file is always the property contents, take a closer look at DJ’s example
