target problem

[betamax]

Quick question (hopefully) I'm building an xml driven gallery and I've got a bit of a problem targetting images.

This works fine:
jpeg = mySection.childNodes[i].attributes.jpegURL;
trace(jpeg);
But I need to add tnIcon so I can target this from a function using 'this':

tnIcon.jpeg = mySection.childNodes[i].attributes.jpegURL;
trace(tnIcon.jpeg);
This nearly works except the first result is 'undefined' the rest of the results are fine.

Any ideas why this is happening and how to solve it?
Many thanks

i would presume mySection.childNodes[0] has no value so if you are using a for loop start the count at 1.

when u trace it before, nothing is traced so you are not seeing undefined where as when u try and trace the variable in tnIcon is returning undefined as there is nothing there.

Hi Tink thanks for your reply, I may have misunderstood you, but i don't think that is the case. The first bit of code outputs this:
pics/01.jpg
pics/02.jpg
pics/03.jpg
pics/04.jpg
pics/05.jpg
pics/06.jpgThe second bit of code outputs this:
undefined
pics/02.jpg
pics/03.jpg
pics/04.jpg
pics/05.jpg
pics/06.jpg

Hmm I just moved this line of code so that its above the function which uses the valuetnIcon.jpeg = mySection.childNodes[i].attributes.jpegURL;....it works, don't ask me why but it works!! :confused:
