Most configuration files in FlightGear are XML-encoded | Most configuration files in FlightGear are XML-encoded property lists. PropertyList-encoded XML files use a subset of XML to map the property tree to XML space and vice versa. PropertyList-XML files are the main mechanism to populate the FlightGear property tree (or a sub branch of it) from XML files, but also to serialize (save) property tree/branch state to an XML file. XML attributes are mainly used as meta-directives for the property tree. | ||
To work with PropertyList-XML files, you can use various means, such as: | |||
* fgcommands | |||
* Nasal (props.nas, io.nas) | |||
* C++ APIs | |||
The root element of each file is always named <PropertyList>. Tags are almost always found in pairs, with the closing tag having a slash prefixing the tag name, i.e </PropertyList>. The exception is the tag representing an aliased property. In this case a slash is prepended to the closing angle bracket. | The root element of each file is always named <PropertyList>.
