Hi,
The following line of an XML transaction causes the message to go to the Dead Letter Queue as soon as it hits the input queue of a broker flow:
<TestTag>Testing</TestTag>
The two characters in front of the word Testing are the keyboard sequence "Ctrl V".
When I remove the two characters, the transaction works fine. These characters are put there when a system user is copying information into a free form field which then is used as the contents of the XML tag.
Is there any way to handle these characters in the broker so that the message does not immediately go to the Dead Letter queue upon hitting the input queue?
Thanks for any help! |

Read the message as BLOB, parse out the bad characters manually, and then reparse as XML.
Or fix the webapp so that the form doesn't allow bad characters!

The characters display as spaces on the input app. It gets there when a user is copying and pasting using Ctrl C and then Ctrl V. How would I parse those particular characters out manually. What would I look for?
Thanks! |

You'd have to look for byte values.
You really want to fix the webapp instead. It's not producing valid XML - ergo it's not meeting the contract between itself and your message flow.

Hex values that form characters outside the XML specification?

| Thanks for the information!! Just trying to now see how I can fix the app not to allow those characters when a user is copying and pasting and doesn't have anything on the clipboard at the time they hit the Ctrl V which is what is causing the weird characters. |
