![]() ![]() And in the model, the tree structure makes it easy to find, retrieve and process the information. The structured text format of XML has advantages on both sides: for humans it is readable and modifiable, even without any special software. One can see that parsing XML is quite easy. The source files of the model can be downloaded from the AnyLogic Cloud. Taken all this together, we now have a model that takes data in XML format from a text file and uses it to create and parameterise objects in the model: getElementsByTagName ( "product" ) Ĭolor color for ( int temp = 0 temp < nList. ![]() normalize ( ) //Second part: Find location, retrieve list of items newDocumentBuilder ( ) īyteArrayInputStream input = new ByteArrayInputStream (inputString. newInstance ( ) ĭocumentBuilder builder = factory. The function readFile(), which reads the file and returns it as a String:ĭocumentBuilderFactory factory = DocumentBuilderFactory. The idea is that objects get created according to the data in the XML file by code and enter the flow at the Enter block. The model consists of a very simple process flow, a basic layout (2 nodes and one connecting path) and a file object. In this example we want to read the data and create products based on it. Mapping can internally switch between DOM, SAX, StAX and so on, without having to change the code. Mapping is adding a layer abstraction between XML parsing and actual working with the XML data. If you only want to search for certain elements or read data to fill own data structures, Pull/Push might be good. If you need to sort, or resolve references between different elements, you need to have the full tree in memory (DOM). ![]() Which one to use depends on your requirements. Mapping: A representation of the XML data in form of Java objects is built.Push: The parser works event based, it triggers functions in your code whenever it finds a certain element or text.Pull: The elements can be iterated over by a cursor, certain elements can be pulled. ![]()
