Expat Library

The library includes minimal numbers of functions of the Expat XML parser. When 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 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. As for the start callback, if the first argument is integer (indicating depth level), the second is a xml tag name; otherwise the two arguments are the key and 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 the xml string by the EXPAT object.

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>");
