Today, I would like to emphasis on exporting data to an xml file in AX 2012.
Extensible Markup Language (XML) defines a set of rules for encoding documents electronically. It allows the creation of all kinds of structured documents to exchange between systems. In Dynamics AX, XML files are widely used across the application.
For example, user profiles can be exported as XML files. Business data, such as financial statements can also be exported as extensible Business Reporting Language (XBRL) files, which are based on XML.
Probably, the main thing that is associated with XML in Dynamics AX is the Application Integration Framework. It is an infrastructure that allows exposing business logic or exchanging data with other external systems. The communication is done by using XML formatted documents. By using the existing XML framework application classes prefixed with Axd, you can export or import data from or to the system in an XML format to be used for communicating with external systems. It is also possible to create new Axd classes using the AIF Document Service Wizard from the Tools menu to support the export and import of newly created tables.
Dynamics AX also contains a set of application classes prefixed with Xml, such as XmlDocument and XmlNode. Basically, those classes are wrappers around the System.XML namespace in the .NET framework.
In this recipe, we will create a new simple XML document by using the latter classes, in order to show the basics of XML. We will create the file with the data from the SalesTable table and will save it as an XML file.
Following are the steps…
Carry out the following steps in order to complete this recipe:
1. Open the AOT and create a new class named ReadorWriteXml with the following code:
public void writeXMLFile()
doc = XmlDocument::newBlank();
nodeXml = doc.createElement(‘xml’);
while select RecId, SalesId,SalesName,CustAccount from SalesTable where salesTable.CustGroup == ‘AGENCY’
nodeTable = doc.createElement(tableStr(SalesTable));
nodeId = doc.createElement(fieldStr(SalesTable,SalesId));
nodeCustAccount = doc.createElement(fieldStr(salesTable,CustAccount));
info(strFmt(‘file is created.’, #filename));
public static void main(Args args)
ReadorWriteXml file = new ReadorWriteXml();
2. Run the class. The XML file sales.xml should be created in the specified folder.Open it using any XML editor or viewer, such as Microsoft Internet Explorer, and review the created XML structure:
How it works…
We start the recipe by creating a new XmlDocument using its newBlank() method,which represents an XML structure. Then we create its root node named xml using the createElement() method, and add the node to the document by calling the document’s appendChild() method.
Next, we go through the SalesTable and do the following for each record:
1. Create a new XmlElement node, which is named exactly as the table name, and add
this node to the root node.
2. Create a node representing the salesId field and its child node representing its value. The salesId node is created using createElement(), and its value is created using createTextNode(). The createTextNode() method basically adds a value as text with no XML tags.
3. Add salesId node to the table node.
4. Create a node representing the sales name field and its child node representing
5. Add salesname node to the table node.
6. Add Cust Account node to the table node.
Finally, we save the created XML document as a file.
In this way, we can create documents having virtually any structure.
