Re: DeleteSelf() method does not trigger on an InfoPath Form

There is a semantic problem with your code. As you iterate through and delete nodes, their positions will change, and the node that was previously at position [2] will now be at position [1] and you will skip over it.

The typical way to approach deleting nodes is to add all the ones you want to delete to an array, then iterate throught the array and call DeleteSelf() on them.

I also suggest walking through your code to figure out just what is going on, and it also looks like you're never setting the modified XML back to your list item at any point.

Here is the full code:

XmlDocument xml = new XmlDocument();

using (Stream s = workflowProperties.Item.File.OpenBinaryStream())
{
xml.Load(s);
}

XmlNamespaceManager man = new XmlNamespaceManager(xml.NameTable);
man.AddNamespace("xsi", "http://www.w3.org/2001/XMLSchema-instance");
man.AddNamespace("xhtml", "http://www.w3.org/1999/xhtml");
man.AddNamespace("xd", "http://schemas.microsoft.com/office/infopath/2003/myXSD/2010-02-09T15:29:07");
man.AddNamespace("my", "http://schemas.microsoft.com/office/infopath/2003/myXSD/2010-02-09T15:29:07");

root = xml.CreateNavigator();

XPathNodeIterator iter = root.Select("/my:myFields/my:grpRequest", man);
int nodesCount = iter.Count;

string app = GetSubstring(workflowProperties.Item["Title"].ToString(), "_", ".xml");

for (int i = 1; i (lessthanequals) nodesCount; i++) --- The sematics for "lessthanequals" cannot be used in a post here
{
XPathNavigator currentNodeItem = root.SelectSingleNode("/my:myFields/my:grpRequest[" + i + "]/my:strApplication", man);
XPathNavigator currentNodeItem1 = root.SelectSingleNode("/my:myFields/my:grpRequest[" + i + "]", man);
if (currentNodeItem1 != null)
{
string appName = currentNodeItem.Value;
string tet = currentNodeItem1.Value;
if (appName != app)
{
currentNodeItem1.DeleteSelf();
}
}
}
workflowProperties.Item.SystemUpdate(false);

Looks like your code was cut off.

DeleteSelf() method does not trigger on an InfoPath Form

I am trying to trigger a WF on an InfoPath form to delete a row from a Repeating Table within the form, when a certain condition is met. The DeleteSelf() method does not throw any error/Exception, but does not execute as well. When I view the form after the WF completes (no exceptions again), all the rows in the repeating table are still there. Note: The WF is being manually started, for testing purposes. Am I missing something here? Here is the code: ************************************************************************************************** XmlDocument xml = new XmlDocument(); using (Stream s = workflowProperties.Item.File.OpenBinaryStream()) { xml.Load(s); } XmlNamespaceManager man = new XmlNamespaceManager(xml.NameTable); man.AddNamespace("xsi", "http://www.w3.org/2001/XMLSchema-instance"); man.AddNamespace("xhtml", "http://www.w3.org/1999/xhtml"); man.AddNamespace("xd", "http://schemas.microsoft.com/office/infopath/2003/myXSD/2010-02-09T15:29:07"); man.AddNamespace("my", "http://schemas.microsoft.com/office/infopath/2003/myXSD/2010-02-09T15:29:07"); root = xml.CreateNavigator(); XPathNodeIterator iter = root.Select("/my:myFields/my:grpRequest", man); int nodesCount = iter.Count; string app = GetSubstring(workflowProperties.Item["Title"].ToString(), "_", ".xml"); for (int i = 1; i
