InfoPath 2010 browser-enabled forms cannot be opened - "The following document is not a valid InfoPath form"
Environment:
SharePoint 2010, InfoPath 2010 browser-enabled forms
Issue description:
We have alot of InfoPath forms in SharePoint 2010. These forms were migrated from InfoPath 2003 client to InfoPath 2010 browser-enabled. Occasionally a few InfoPath forms cannot be opened in browser with the following error:
There has been an error while loading the form.
The following document is not a valid InfoPath form: {path of form}
Cause:
After doing some research and comparision, I noticed that we have a rich text field in the form that users use to copy and past html content from the internet. The pasted content includes the following string that caused this issue:
<?XML:NAMESPACE PREFIX = "[default]" http:="http:" xmlns:http="urn:http" ?>
Resolution:
- Download the form to local machine. Open the form in notepad. Find the above string and delete.
- From SharePoint library, find the affected item.
- Checkout the item (if checkout is required)
- Upload a file to the library, point the path to the local path of the newly saved xml file.
- Save
- Open the form from SharePoint, it should open in browser without any issue.
