Expat Library

The library includes minimal numbers of functions of the Expat XML parser. If an XML file contains non-ASCII characters, it should be processed line by line with each line encoded as UTF-8 string.

Function	Parameter Type	Remark
expat()		Creates and returns an object to handle xml stream using the EXPAT library.
.version()		Returns EXPAT version string.
.callback(start, end, data)	string, string, string	Sets callback functions to handle xml stream produced by the EXPAT object. For the start callback, if the first argument is an integer (indicating depth level), the second will be a xml tag name; otherwise the first will be the key and the second will be the value of a xml attribute. The end callback function should handle one argument as a closing xml tag. The data callback function should handle one argument as a string.
.parse(str)	string	Parses an xml string.

Example

load("expat.dll");

function f1(a, b)
{
    csv(a, b);
}

function f2(a)
{
    csv(a);
}

function f3(a)
{
    csv(a);
}

xml = expat();
xml.version();

xml.callback("f1", "f2", "f3");

xml.parse("<a>abc<b>ABC</b></a>");
