I'm testing some XML stuff locally on UV PE 11.2 and I've run into a problem I
can't figure out. I hope someone else knows what's going on here and has a
work-around.
I'm running this test on CentOS 6.5 with UniVerse PE 11.2. I get a core dump
as soon as I attempt the XMAPOpen. It appears to only happen when the
ColumnMap Node begins with a comma. The same data, map and code works without
problem on an AIX machine.
MAP ...
<?xml version="1.0" encoding="UTF-8"?>
<!-- DOCTYPE U2XMAP SYSTEM "U2UXMAP.DTD" -->
<U2XMAP Version="1.0" Name="XMAP1">
<TABLECLASSMAP MapName="M1" StartNode="/RESPONSE" TableName="WEATHER">
<ColumnMap Node="/HOME/text()" Column="@ID" />
<ColumnMap Node="/FOREIGN/text()" Column="FOREIGN" />
<ColumnMap Node="/UNITS,text()" Column="UNITS" />
<ColumnMap Node="/NUMBER,text()" Column="NUMBER" />
<ColumnMap Node=",INFO,DATE/text()" Column="DATE" />
<ColumnMap Node=",INFO,CITY/text()" Column="CITY" />
<ColumnMap Node=",INFO,TEMP/text()" Column="TEMP" />
</TABLECLASSMAP>
</U2XMAP>
XML DATA...

CODE...
INCLUDE UNIVERSE.INCLUDE XML.H
open '&XML&' to xml.file else stop
xml.id = "temps.xml"
map.id = "temps.map"
read xml.rec from xml.file,xml.id else
crt "Can't read ":xml.id:" from &XML& file"
stop
end
convert @am to '' in xml.rec
ERR1=XDOMOpen(xml.rec,XML.FROM.STRING,DOMH)
IF ERR1 # XML.SUCCESS THEN
crt "Can't do XDOMOpen()"
RETURN
END
ERR1=XMAPOpen(xml.rec, XML.FROM.STRING, map.id, XML.FROM.FILE, XMAPhandle)
IF ERR1 # XML.SUCCESS THEN
crt "XMAPOpen failed"
RETURN
END
This is the top part of the resulting stack dump:
