* This example will access the following pieces of data:
* NDC Labeler Code, Firm Name, 0002, Eli Lilly and Company, ...

* First navigate to the Worksheet named "NDCLabelerCode"
loXWorksheet = loXlsDoc.GetChildWithAttr("Worksheet","ss:Name","NDCLabelerCode")

* Next, get the Table node:
x = loXWorksheet.GetChildWithTag("Table")

* How many immediate child nodes?
lnNumChildren = x.NumChildren

* Loop over each Row and access the cell contents.

FOR i = 0 TO (lnNumChildren - 1)

    * Navigate without creating new XML objects
    lnSuccess = x.GetChild2(i)

    IF (x.TagEquals("Row")) THEN

        lcData0 = x.ChilkatPath("Cell[0]|Data|*")
        ? lcData0

        lcData1 = x.ChilkatPath("Cell[1]|Data|*")

    * Navigate back up.
