Re: xml woes
Robby,
I suspect this is probably a typo, but the closing tag of your xml packet
isn't a closing tag.
Both of which bail.. the first one bails without an actual error,
. just the araydeleteat() being the line it error'd at.
But when I looked in to the logs,
It says java.lang.IndexOutOfBoundsException and searching google only gave
two results,
. both of which have no bearing on the situation at hand.
Basically, this means that CF is trying to access a element in an array,
past the end of the array. eg. there are 2 elements in the array and you
are trying to access the third element.
Looking at your code. The reason for this is that you are using the yes
variable to store an array in both your outer i loop and your inner j
loop. You need to use different variables for each loop, otherwise you'll
be overwriting your outer array everytime you go around your inner array.
Also, I suspect that you are trying to delete the wrong bit of your array.
You need to be
Try this : (I warn you there maybe errors. I typed this from your code and
off the top of my head without testing it)
cfscript
// Loop over the children of c_dropx eg. drop name=abba and drop
name=1221
for (i=1; i lte arraylen(c_dropx); i=i+1) {
// bung the structure for the current element into a new variable for ease
thisElement = StructNew();
thisElement = c_dropx[i];
// Check the attributes of thisElement to see it is abba.
if (thisElement.xmlattributes[name] is abba)
// Loop over the children for thisElement, which would be the same as
looping over the drop_item elements
for (j=1;j lte arraylen(thisElement.xmlChildren); j=j+1) {
// Store the current child structure in a variable thisChild for
ease
thisChild = StructNew();
thisChild = thisElement.xmlchildren[j];
if (thisChild.xmltext is a) {
WriteOutput(j - thisChild.xmltextBR);
arraydeleteat(thisElement.xmlchildren, j);
}
}
}
/cfscript
The element at position 5 of dimension 1, of array variable TT, cannot
be
found is the one on the second try, and with it, the array itself is
cfdumped, and
there is 5 elements in the array, I've read the docs
I've double checked what I know how. What the hell am I doing wrong?
To be honest, I'm not sure what's up with your second bit of code. I
really need to play with xml in CFMX some more, but here's the cfscript
version of your code. I suspect, that you have the same problem here as you
do above, where you are trying to delete the array from the wrong place in
the data structure.
cfscript
for (i=1;i lte arraylen(tt); i=i+1) {
if (tt[i].xmltext is a) {
arraydeleteat(tt, i);
}
}
/cfscript
Hope some of this helps some how.
Regards
Stephen

RE: xml woes
If I understand your question, you aren't having XML woes, you are having ArrayDeleteAt() woes. My first bit of advice when troubleshooting a problem like this would be to simplify your code. Breaking a complex problem down into smaller pieces allows you to focus on the part that's breaking without being distracted by the other stuff (like the fact that you were using XML to generate your array). Also, in a related note - you've posted a gigantic amount of code into this email, and few people on the list are likely to be willing to go through it line by line and figure out everything it's doing. That's just free unsolicited advice, though it doesn't directly solve the problem at hand. I think your problem is a pretty basic one. Essentially, you are doing this at the end of your code: cfloop from=1 to=#arraylen(tt)# index=i cfif tt[i].xmltext eq a cfset arraydeleteat(tt, i) /cfif /cfloop Looks to me like the problem is that when your array's length is evaluated at the beginning of the loop it's 5, but as soon as the cfif returns a match, you end up deleting an item from the array. This effectively changes the array's length *immediately* to 4 items. Then as the loop continues on to the 6th item, (which no longer exists - you deleted it) the server throws an exception. The java.lang.IndexOutOfBoundsException is saying that your index 5 is out of bounds because your array's only got 4 items in it.
