Getting XML data into Temp-Table in Progress 4GL/OpenEdge ABL

so this should be pretty simple. I'm trying to get data from a XML file in an URL and parsing it into a temp-table so I can use the data in the rest of my program. I've written a code but at the end, DISPLAY PAPEL DESCRICAO. doesn't show anything. Am I doing something wrong? The entire code with the XML link:

DEF TEMP-TABLE CMA NO-UNDO
FIELD PAPEL AS CHAR
FIELD DESCRICAO AS CHAR
FIELD ULTIMO AS DEC
FIELD DIFERENCIAL AS DEC
FIELD VARIACAO AS DEC
FIELD FECHANT AS DEC
FIELD COMPRA AS DEC
FIELD MINIMA AS DEC
FIELD MAXIMA AS DEC
FIELD VENCIMENTO AS INT
FIELD HORA AS CHAR
FIELD DATA AS DATE.

DEF VAR cSourceType AS CHAR NO-UNDO.
DEF VAR cFile AS CHAR NO-UNDO.
DEF VAR cReadMode AS CHAR NO-UNDO.
DEF VAR cSchemaLocation AS CHAR NO-UNDO.
DEF VAR lOverrideDefaultMapping AS LOGICAL NO-UNDO.
DEF VAR cFieldTypeMapping AS CHAR NO-UNDO.
DEF VAR cVerifySchemaMode AS CHAR NO-UNDO.
DEF VAR lReturn AS LOGICAL NO-UNDO.

ASSIGN
cSourceType = "FILE"
cFile = "http://sfeed-cot01.cma.com.br/clientes/cocamar/cbot.xml"
cReadMode = "EMPTY"
cSchemaLocation = ?
lOverrideDefaultMapping = ?
cFieldTypeMapping = ?
cVerifySchemaMode = ?.

lReturn = TEMP-TABLE CMA:READ-XML(cSourceType, cFile, cReadMode,
cSchemaLocation, lOverrideDefaultMapping, cFieldTypeMapping,
cVerifySchemaMode).
IF lReturn THEN
FOR EACH CMA NO-LOCK:
DISPLAY CMA.PAPEL CMA.DESCRICAO.
END.


Any help is much appreciated.
