        <gx:coord>127.03998 37.51816 101.8</gx:coord>
        <gx:coord>127.03958 37.51816 106.8</gx:coord>
        ..
        .

as you know I can access dom using find,

//data is the xml(kml) file loaded.
$(data).find('Placemark')

this works correctly, return object array.

but,

$(data).find('gx:Track')

this doesn't work, return empty jquery object.

$(data).find('gx:coord')

also doesn't work.

anyone who know the reason and solution?

My suspicion is that it see's the :track part of the string as a jQuery pseudo-selector (like :first-child etc).

You can escape the : by putting a \\ before it, so your selector would become:

$(data).find('gx\\:Track')

http://api.jquery.com/category/selectors/ for the explanation of controlled selector characters.

escape the : with \\

Like this:

$(data).find('gx\\:Track')

I believe that jQuery selectors do not recognize XML namespaces.

You can try this: $(data).find('gx\:coord') but something tells me it will not work either.
