I would like to retrieve information from a database using an Export Mapping (Post). The database needs an xml request body in the following form to return a xml body with the information of the UserName and Mail related to a specific UserId: (1) <?xml version="1.0" encoding="UTF-8"?> <Root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="***"> <Transaction xmlns=""> <PersUser DmlCommand="SQ"> <UserId>***</UserId> <UserName/> <Mail/> </PersUser> </Transaction> </Root> I used the following xml schema: <?xml version="1.0" encoding="utf-8"?> <xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="***"> <xs:element name="Root"> <xs:complexType> <xs:sequence> <xs:element name="Transaction" xmlns=""> <xs:complexType> <xs:sequence> <xs:element name="PersUser"> <xs:complexType> <xs:sequence> <xs:element name="UserId" /> <xs:element name="UserName" /> <xs:element name="Mail" /> </xs:sequence> <xs:attribute name="DmlCommand" type="xs:string" use="required" /> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> The microflow calling the ‘Export to XML’-activity looks like this: where I set the attributes of “PersUser”, as Mendix demands an input for every attribute: The “Export to XML”-activity results in a string, as I wanted to check the output of the export mapping: The string finally contains an xml document that looks like this: But this request body results in an error when sending it to the database. How do I get the body to look like the needed xml body (1)? Thanks in advance!
