Now we want three XML files, each containing one book, to be based on the same schema called Books.xsd. These XML files, called BookTitle1.xml, BookTitle2.xml, and BookTitle3.xml, will be used as input files. Before changing the component settings, save your mapping as an .mfd file in the following folder: <Documents>\Altova\MapForce2022\MapForceExamples\Tutorial\BasicTutorials. To instruct MapForce to process multiple XML instance files, double-click the header of the source component. Enter BookTitle*.xml as an input file in the Component Settings dialog box. The asterisk ( * ) in the file name instructs MapForce to use all the files with the BookTitle prefix as mapping inputs. Because the path is relative, MapForce will look for all BookTitle files in the same directory as the mapping file. You can also enter an absolute path if necessary.
