EC, I have another question (or anyone that feels they can answer).
I notice in the IRC bot code that you can get banned for hitting the web page
too often.
Would there be a way to bring in the XML data without an HTTPRequest from a
local file? Say something I saved from the last successful pull from the live
file and defined as:
var localfile = js.exec_dir + "solar.php";
where solar.php was saved from a previous lookup less than an hour ago?
My awful attempt to do this currently looks like this:
if((time() - last_solar_update) > 60*60) {
try {
var solardata = new XML(
(new HTTPRequest()).Get(
'
http://bbs.kd3.us/sol/solarxml.php.xml'
).replace(
/<\?[^?]*\?>/g, ''
)
).solardata;
} catch (err) {
log('Shit done borked! ' + err);
}
} else {
try {
var localfile = js.exec_dir + "solar.php";
var localPHPfile = new File(localfile);
localPHPfile.open("r"); // open file with read access
var localXMLfile = localPHPfile.readAll();
var fixedXMLfile = localXMLfile.replace(
/<\?[^?]*\?>/g, ''
);
var solardata = new XML(
fixedXMLfile.solardata);
} catch (err) {
log('Shit done borked! ' + err);
}
localPHPfile.close();
}
Also, if this is simply a crazy thing to try and do, feel free to let me know.
localXMLfile keeps coming back as null and I'm not sure where I've gone wrong
anymore.
