problem with XML package
Hi List,
I have used XML in R version 2.9.2. The code is working fine using Rv2.9.2
and its related XML package. Now I am using Rv2.13.1 and its related XML
package, but I get the following error:
Error in UseMethod("xmlName", node) :
no applicable method for 'xmlName' applied to an object of class "NULL"
Any idea?
Thanks
Arvin

How to parse XML
I would like to learn how to parse a mixed text/xml document I
downloaded from the sec.gov website (see example below). I would like
to parse this to get the value for each xml tag and then access it
within R, but I don't know much about xml so I don't even know where to
start debugging the errors I am getting in this example code. Can
anyone help me get started?
Thanks, Roger
