I have an xml document that I have imported that is 22970 rows (records) in length.  An example of my xmlDoc.xml
is below:

- <xmlDoc>
- <row>
  <transDate>12/Jan/2011</transDate>
  <sitecode>50</sitecode>
  <wbs1>11</wbs1>
  <wbs2>1700</wbs2>
  <glAccount>1520D</glAccount>
  <cost>153.31560869827</cost>
  </row>
- <row>
  <transDate>11/Jan/2011</transDate>
  <sitecode>50</sitecode>
  <wbs1>11</wbs1>
  <wbs2>1700</wbs2>
  <glAccount>1520D</glAccount>
  <cost>21.496070612981</cost>
  </row>
