Program miss result in page that have.
but no tall the time.

Please take a look at my code and tell me why.

//Extracts META tags and nombre
//create columnas
DataExtractor.SetColumns(4);
DataExtractor.AddHeader(1, 'URL');
DataExtractor.AddHeader(2, 'Title');
DataExtractor.AddHeader(3, 'Meta Keyword');
DataExtractor.AddHeader(4, 'Meta Description');
DataExtractor.StartNewResult();
DataExtractor.AddResult(1, document.location.pathname);
DataExtractor.AddResult(2, document.title);
var mt = document.getElementsByTagName('meta');
if (mt.length 0) {
for (i=0; imt.length; i++) {
if (mt[i].name == "keywords") {
DataExtractor.AddResult(3, mt[i].content);
}
if (mt[i].name == "description") {
DataExtractor.AddResult(4, mt[i].content);
}
}
}
