A very very strange removechild error, or I am missing something really important.

Removing all rows in a repeating table using removechild with vb.net code as below:


01 Dim numRows = thisXDocument.DOM.selectNodes("//d:Details").length()
02 Dim deleteNode As IXMLDOMNode
03 thisXDocument.UI.Alert("Total of " & numRows & " to be deleted")
04 For i = 1 To numRows
05 thisXDocument.UI.Alert("Deleting Row " & i)
06 deleteNode = thisXDocument.DOM.selectSingleNode("//d:Details[" & i & "]")
07 If deleteNode Is Nothing Then
08 ' Do Nothing
09 End If
10 deleteNode.parentNode.removeChild(deleteNode)
11 Next i


Now if the Repeating Table had 10 rows, I would assume the code above removes all the 10 rows, BUT NO; It removes Rows 1,3,5,7,9 and leaves behind Rows 2,4,6,8,10. And while doing that it does alert at line number 5, 'Deleting Row 1', 'Deleting Row 2', 'Deleting Row 3', etc so on for all 10 rows. numRows contains a value of '10' at line number 01 and alerts the value correctly at line number 03

So in the repeating table, we now have Rows 2,4,6,8,10

Next I execute the code, and Row 4 & Row 8 (from the original table) are still there.

Its skipping a row everytime.

Any thoughts? I have to resolve this. Any other options to remove all rows in a repeating table?

Thanks.

Hi,

Your code can't work because when you delete the first node. everything is shifted by 1: 2 becomes 1. Next loop, you target i=2 (you then miss 1 that used to be 2) and so on.

Try to always delete Details[1] not "i", or try to use something like:
thisXDocument.DOM.selectNodes("/my:myFields/my:group1/my:group2")
Dim oNN As IXMLDOMNode
For Each oNN In thisXDocument.DOM.selectNodes("/my:myFields/my:group1/my:group2")
oNN.parentNode.removeChild(oNN)
Next
