Hello,

I'm attempting to read information from an XML into a data frame in R using
the "XML" package. I am unable to get the data into a data frame as I would
like.  I have some sample code below.

*XML Code:*

Header...

Data I want in a data frame:

   <data>
  <row BRAND="GMC" NUM="1" YEAR="1999" VALUE="10000" />
  <row BRAND="FORD" NUM="1" YEAR="2000" VALUE="12000" />
  <row BRAND="GMC" NUM="1" YEAR="2001" VALUE="12500" />
  <row BRAND="FORD" NUM="1" YEAR="2002" VALUE="13000" />
  <row BRAND="GMC" NUM="1" YEAR="2003" VALUE="14000" />
  <row BRAND="FORD" NUM="1" YEAR="2004" VALUE="17000" />
  <row BRAND="GMC" NUM="1" YEAR="2005" VALUE="15000" />
  <row BRAND="GMC" NUM="1" YEAR="1967" VALUE="PRICLESS" />
  <row BRAND="FORD" NUM="1" YEAR="2007" VALUE="17500" />
  <row BRAND="GMC" NUM="1" YEAR="2008" VALUE="22000" />
  </data>

*R Code:*

doc< -xmlInternalTreeParse ("Sample2.xml")
top <- xmlRoot (doc)
xmlName (top)
names (top)
art <- top [["row"]]
art
**
*Output:*

> art<row BRAND="GMC" NUM="1" YEAR="1999" VALUE="10000"/>




This is where I am having difficulties.  I am unable to "access" additional
rows; ( i.e.  <row BRAND="GMC" NUM="1" YEAR="1967" VALUE="PRICLESS" /> )

and I am unable to access the individual entries to actually create the
data frame.  The data frame I would like is as follows:

BRAND    NUM    YEAR    VALUE
GMC        1          1999      10000
FORD       2          2000      12000
GMC        1          2001       12500
    etc........

Any help or suggestions would be appreciated.  Conversly, my eventual goal
would be to take a data frame and write it into an XML in the previously
shown format.

Thank you

AG
