The Document Form variable is not an xml type like xfaForm or xml. You can only use xPath on xml based variable type.
What you need to do is similar to what I've explained in the other post. You need to take the data out of the Document Form using an xPath expression into a xml variable. Then you'll be able to use xPath to get to your data.
Make sure you have xml is the Document Form and not PDF. Otherwise you'll have to get the PDF out of the Document Form variable first, then extract the data, then put it in a xml variable.
Are you sure /process_data/NameForm/object/@document contains xml and not the PDF?
Usually people use a Document Form variable to store PDF and xfaForm variable to store XDP data (xml of the form).
Can you give me a bit more background on how you populate your Document Form variable? Is it pointing to a PDF or an XDP? Which render service are you using?
My Document Form variable is pointing to a file.Pdf.<br />(But with the LC tutoriel a xfaForm variable is pointing to a file.pdf : Mortgage Loan).<br />An other person made a little process(successive signing validation).<br />I want to get a field value from this form (which is associate to a Document form variable). After I call a webservice but I need this field value.<br />I tried with "getFormField","convertPDFtoXDP" activities.<br />In convertPDFtoXDP activity : I create a xfaForm variable an I tried :<br />Input Document : (Xpath expression)<br />/process_data/inPleaseSignHereDocumentForm/object/@document<br />(Document Form)<br />Converted XDP Document : (variable)<br />NameXfa (xfaForm)<br />But exception :<br /><br />Cannot coerce object: <document state="passive" senderVersion="3" persistent="true" senderPersistent="false" passivated="true" senderPassivated="true" deserialized="true" senderHostId="127.0.0.1/172.31.196.171" callbackId="0" senderCallbackId="22" callbackRef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isLocalizable="true" isTransactionBound="false" defaultDisposalTimeout="600" disposalTimeout="600" maxInlineSize="65536" defaultMaxInlineSize="65536" inlineSize="0" contentType="application/octet-stream" <br />AND MORE<br /><br />Thanks.
So your Document Form variable is pointing to a PDF and the submit button on the form is probably submitting PDF.
The Document Form/object/document probably contains PDF and not the xml data. You can double check the submit button on the form to see what it submits.
Now, you can extract the PDF and put it in a document variable and then use the Form Data Integration module to extract the data (under Common).
I tried to affect this xml variable to /process_data/xfaName/object/data. (no exception but when I search my field value /process_data/xfaName/object/data/xdp/datasets/data/FSFIELDS_/__fieldnode__//Namefield nothing)
The signature field dat is not carried in the submitted XML. So you cannot XPath to it and get a value for it. There are server side calls in Security Server (part of LiveCycle) that will get information about the signature (and you will have to submit the whole PDF to get the signature bits out of it)
