getElementsByTagName results are undefined about xmldom

[jindw]

use:
console.log(entries.item(0).nodeName);

i have published a new version:0.1.7 just now. so that you can visit as nodeList[index](it's not w3c standard)
http://www.w3.org/TR/DOM-Level-3-Core/core.html#ID-536297177

thanks for your suggestion

Ah, my fault. Couldn't find the proper way to access the results. Thanks, jindw!

Maybe another problem:

console.log(entries.length);
console.log(entries[0].nodeName);

...prints 1 and entry. That's what got me confused in the first place.

But the above solution (item(0)) works for my needs. Thanks again.

before v0.1.7 :LiveNodeList is not initialized by default.
but when you access length ,it'is initialized and can access it by index. that is all.

i published a new version 0.1.7 just now ,you can try it again.

as w3c described, NodeList is keep alive,if you access child by index(not from item(), it's not standard), NodeList is not keep alive(document change is not reflect on NodeList)

Tried version 0.1.7 and now it's initialized by default, thanks!

But I understand why it's bad practice to access the elements by index. Thanks for explaining! I should read the specs instead of tutorials.
