Handling XML and JSON files with the AL language

The AL language extension has native support for handling XML and JSON documents.An XML document is represented by using the XmlDocument data type, as explained at https://docs.microsoft.com/en-us/dynamics365/business-central/dev-itpro/developer/methods-auto/xmldocument/xmldocument-data-type.The following code shows how you can import an XML file and load it into an XmlDocument object:

local procedure ImportXML()
    var
        TempBlob : Codeunit "Temp Blob";
        TargetXmlDoc : XmlDocument;
        XmlDec : XmlDeclaration;
        Instr: InStream;
        filename: Text;
    begin
        // Create the Xml Document
        TargetXmlDoc := XmlDocument.Create;
        xmlDec := xmlDeclaration.Create('1.0','UTF-8','');
        TargetXmlDoc.SetDeclaration(xmlDec);
        // Create an Instream object & upload the XML file into it              
        TempBlob.CreateInStream(Instr);
      ...
