Validating xml in pipeline - if not valid drop file in invalid folder

Question

My goal is to receive an xml file through a customized pipeline so I can validate it.  If it's valid I drop it in 'valid' folder.  Then my orchestration will pick it from that location and do whatever it will do with it.  This works fine.
 But if the xml file is NOT valid I want to drop it in a an 'INVALID' folder and have a different orchestration pick it up and send an email to me.  Is this possible?  In my pipeline I don't have a dissambler, just an XMLValidator with the appropriate
schema in the document schemas collection.  When I do drop in an 'invalid' xml file according to the schema, the pipeline is suspended.  How can I drop that invalid xml file into a folder?
I've been learning/working with BizTalk for about 3 months.  I'm trying to keep this simple and avoid doing any custom c# code until I'm more comfortable with BizTalk.
thank you in advance for your expert advice.

Hi Jean,
Your validation pipeline should promote the "MessageType" property of the message (if the orchestration doesn't have any other filters and if the orchestration's receive shape has a message type pointing to specific message). Its seems that when your validation
component validate any incoming message, after its process it shall promote the message type property of the message. Other wise you would not have any subscriber for the message published. The error "The published message could not be routed because no subscribers
were found" is due to this issue. i.e your orchestration subscription doesn't match to the message outputted by your custom vaidation component.
Not sure what is the full functionality of your custom validation component. if its simply validating the message, you can still get this functionality by using XML-Receive pipeline and set the property "Validate Document" to "True" and by specifying the
"DocumentSpecNames" to the schema which you want to validate the incoming message against.
If you're using custom pipeline to do standard validation, then follow like this:
Receive Port (with Enable routing for Failed Messages enabled)  Receive Location with XML-Receive pipeline  (Validate Document" to "True" and by specifying the "DocumentSpecNames" to the schema which you want to validate )
Bind the Receive Port to Orchestration - Do your process as normal
Create a send port with above filter for ErrorReport and configure this send port to send the invalid message to your invalid folder.
If you're using custom pipeline to something more than standard validation of XML-Receive pipeline , then follow like this:
Receive Port (with Enable routing for Failed Messages enabled)  Receive Location with Your custom validation pipeline component.
Ensure your custom pipeline component promotes the message type property as
string systemPropertyNS = @”http://schemas.microsoft.com/BizTalk/2003/system-properties”;
outboundMsg.Context.Promote(“MessageType”, systemPropertyNS, “http://NameSpace#RootNode”);
replace the outboundMsg to the outbound message you output in your custom validation component. And message type to relevant value as yours. Or by some means ensure your custom pipeline output the message with matces to subcription expected by your Orchestration.
Bind the Receive Port to Orchestration - Do your process as normal
Create a send port with above filter for ErrorReport and configure this send port to send the invalid message to your invalid folder.
