[XML-SIG] Help with removeChild()
Thu, 10 May 2001 16:03:40 +0200
Your solution below works great! I have discovered something else quite
instructive (at least to me). When I first saw your solution, I thought
"oh, I've tried that already". Silly of me. What I had tried was not
exactly the same, but seemingly close. I had set children =
node.childNodes *without* the final '[:]'. In testing the solution below,
I found that if the [:] is left out, the result is the same as I got before
(an incorrect trimming); however, with the [:] it works fine. I'm sorry if
this is a newbe kind of confusion. I had always thought "list" was
equivalent to "list[:]", but apparently not.
Thank you again!
