Need some direction. I am using urlTransfer to save a file to tmp on Roku. I think need to parse the file. When I get the file it comes in looking like the following:

<?xml version="1.0" encoding="UTF-8" ?>
<schedule>
<DAY attr="2014-11-4">
	<time attr="06:00 am">
			<show name="My Show">
				<sid>6978</sid>
				<network>My Channel</network>
				<title>Season 17, Episode 277</title>
				<ep>17x277</ep>
				<link>http://www.mytv.com/My Show/episodes/1065649497</link>
			</show>
 	</time> 
</DAY>

</schedule>   

I have only pasted part of file to give idea of what it looks like. I have tried the following code to extract the network but am not getting any thing back. Not sure if I am doing this correctly. I know the file is populated. I am having trouble with which field to use for on. Do I use it on schedule, day, time? Thanks for any help

readxml=ReadAsciiFile("tmp:/status.temp")
xmlfilelist = CreateObject("roXMLElement")
if xmlFileList.Parse(readxml) then
 For Each day in xmlFileList.schedule
        network = day.network.GetText()
        Print"NETWORK. . "network
		 Next
End If

Can somebody give me an example of how to extract the values of day, time, show, and network of the following, would be greatful. Thanks

<?xml version="1.0" encoding="UTF-8" ?>
<schedule>
<DAY attr="2014-11-4">
	<time attr="06:00 am">
			<show name="My Show">
				<sid>6978</sid>
				<network>My channel</network>
				<title>Season 17, Episode 277</title>
				<ep>17x277</ep>
			</show>
       </time>
</DAY>
</schedule>

x.day@attr
x.day.time@attr
x.day.time.show@name
x.day.time.show.network.GetText()

--Mark

Thanks RokuMarn but I get an invalid back. The readxml is the file being parsed. When executed I get invalid, invalid, invalid,0.
Thanks again

xmlfilelist = CreateObject("roXMLElement")
xxml=xmlFileList.Parse(readxml)
if xmlFileList.Parse(readxml) then
PRINT"PASSED. . ."
day=xmlfilelist.day@attr
time=xmlfilelist.time@attr
show=xmlfilelist.day.time.show@name
network=xmlfileList.day.time.show.network.GetText()
print day
print time
print show
print network
END IF

It should've worked (it surprised me a little roXml dot-ing to be case-insensitive, so i tried - and it is):

BrightScript Debugger> x.parse("<schedule><DAY attr='2014-11-4'>   <time attr='06:00 am'>         <show name='My Show'>            <sid>6978</sid>            <network>My channel</network>            <title>Season 17, Episode 277</title>            <ep>17x277</ep>         </show>       </time></DAY></schedule>")
BrightScript Debugger> ? x.day@attr
2014-11-4
BrightScript Debugger> ? x.day.time@attr
06:00 am
BrightScript Debugger> ? x.day.time.show@name
My Show
BrightScript Debugger> ? x.day.time.show.network.GetText()
My channel

Use genXML() to see what actually got parsed (e.g. ? xmlFileList.genXML(0) ).

Thanks again. I found the problem. I only posted one entry from the file but the real file has multiple entries. When I ran the code using the file with only one entry I get the values. I guess I need to use array for each value and a for each to populate the array.
Thanks again

[btpoole]

Would the following be the correct way to create an array for Day in the above xml file assuming there are multiple entries? I get an error stating: Runtime: FOR EACH value is not an enumerable object. I know there are multiple "DAY" in the file.

daylist=[]
xmlfilelist = CreateObject("roXMLElement")
for each DAY in xmlFileList
daylist.Push({
	DAY: {DAY: xmlfilelist.day@attr}
	})
End For

[EnTerr]

for each day in xmlFileList.DAY:   'this returns a list of DAYs; xmlFileList is not really a list but roXmlElement
    for each time in day.time:
        for each show in time.show:
            'do the due
        end for
    end for
end for

Thank you EnTerr for your help. I hate to keep requesting advice on this but I am really having difficulties. The idea is that I am creating a simple program guide. I use urlTransfer to write a file from a url that produces an xml file with program info. I get the file, write it, read it run genXML(0). The result comes back showing all the information. When I attempt to populate and array with the DAY and print it to verify it's actually getting something, I get a print for each that says <Component: roAssociativeArray>. When I first posted I had cut the xml file just to show one entry, I am able to extract that one entry but not able to perform a for each that would gather each. Am I totally missing something here? If i curl the url and save it and open in notepad++, the header shows<?xml version="1.0" encoding="UTF-8" ?>, so I assume I am getting an xml in correct format.
Thanks again

[code}
xfer=CreateObject("roUrlTransfer")
xferport=CreateObject("roMessagePort")
xfer.SetMessagePort(xferport)
xmlurl="http://services.tvrage.com/feeds/fullschedule.php?country=US"
xfer.seturl (xmlurl)
xfer.GetToFile("tmp:/status.temp")
readxml=ReadAsciiFile("tmp:/status.temp")
xmlfilelist = CreateObject("roXMLElement")
xxml=xmlFileList.Parse(readxml)
daylist=[]
if xmlFileList.Parse(readxml) then
PRINT"PASSED. . ."
for each day in xmlFileList.DAY
daylist.Push({
DAY: xmlFileList.DAY
})
Print"daylist. . . "daylist
end for
else
PRINT"DID NOT PASS"

END IF

No sweat - that's because PRINT outputs only the top level of nested structures:

BrightScript Debugger> ? {a: 1}
a:  1

BrightScript Debugger> ? [ 1 ]
 1

BrightScript Debugger> ? [ {a: 1} ]
<Component: roAssociativeArray>

The last two are confusing, i agree - there is no hint that what is output is a vector and not scalar.

I am quite unclear on while you are doing that dictionary-inside-array thing though! Looking at your feed, you have a dictionary indexed-by-date, containing dictionary indexed-by-time, containing... well either list of shows or dictionary indexed-by sid or name. How you are going to ingest the data depends on how you are going to use it - so i cannot guess what you need exactly.
