I have a file attachment control, in a repeating section so that there can be more than one, that need to be saved to a SharePoint list.  I have it set up so that when an end user attaches a file with an invalid character in the file name, they will receive a message letting them know they have to rename the file before they can attach it and then the rule removes the file from the attachment field (leaving it blank).  I can get this to work great on the first file attachment, but if there are multiple attachments, the rule doesn't work on anything after the first attachment. 

Here's how I did it:  I set a rule on the file attachment control that when it changes, to set the qRules Command field to: concat("GetAttachmentAttribute /xpath=/my:myFields/ my:attachmentsSection/my:group19/my:Attachments/my:attachment [", count(preceding-sibling::Attachments/attachment) + 1, "] /attr=Name")  then I set the Name field to result.  As mentioned, it works perfectly on the first file attached, but when I try it on the 2nd file attached, the error in the Qrules error field reads "Failed to select the attachment node.". 

 Any ideas?

Hi-

From this xpath:

/my:myFields/ my:attachmentsSection/my:group19/my:Attachments/my:attachment

Which is the repeating node?

The repeating node is Attachments.  See screen shot that I have attached.

I did try changing my command to this: concat("GetAttachmentAttribute /xpath=/my:myFields/ my:attachmentsSection/my:group19/my:Attachments/my:attachment [", count(preceding-sibling::Attachments) + 1, "] /attr=Name")   but it still gave me the same error.

Since the repeating node is my:Attachments, then that's the node that needs the [] (square brackets)

/my:myFields/ my:attachmentsSection/my:group19/my:Attachments[1]/my:attachment

/my:myFields/ my:attachmentsSection/my:group19/my:Attachments[2]/my:attachment

etc.

Does that makes sense?

Yes that makes perfect sense.  Wish I would've realized that hours and hours ago! 

I changed it to read: concat("GetAttachmentAttribute /xpath=/my:myFields/ my:attachmentsSection/my:group19/my:Attachments[", count(preceding-sibling::Attachments) + 1, "]/my:attachment /attr=Name")

and it works perfectly!  Thank you so much Ernesto!
