om.XmlReader.createFileReader

Creates an XML reader object from a file.

Syntax

om.XmlReader.createFileReader(
   path STRING )
  RETURNS om.XmlReader
  1. path is the path to an XML formatted file.

Usage

Use the om.XmlReader.createFileReader() method to create a new om.XmlReader object, to process the XML data from a file input stream.

To hold the reference to an XmlReader object, define a variable with the om.XmlReader type.

Note: Files encoded in UTF-8 can start with the UTF-8 Byte Order Mark (BOM), a sequence of 0xEF 0xBB 0xBF bytes, also known as UNICODE U+FEFF. When reading files, Genero BDL will ignore the UTF-8 BOM, if it is present at the beginning of the file. This applies to instructions such as LOAD, as well as I/O APIs such as base.Channel.read() and readLine().

Example

DEFINE r om.XmlReader
LET r = om.XmlReader.createFileReader("cars.xml")
...
