RE: [flexcoders] finding and removing nodes from xml

[Peter Farland]

Oops, minor correction, that should be length - 1 in the initial state
of the loop (although the AVM doesn't complain about the deletion of an
undefined entity).
 
var xmlList:XMLList = xml..*.(attribute("id") == "6" || attribute("id")
== "24");
for (var i:int = xmlList.length() - 1; i >= 0; i--)
{
    delete xmlList[i];
}

Does something like this work (based on your original email)? The trick
is to loop over the XMLList backwards so that you don't have to correct
the index each time the list gets smaller from the delete operation.

var xmlList:XMLList = xml..*.(attribute("id") == "6" || attribute("id")
== "24");
for (var i:int = xmlList.length(); i >= 0; i--)
{
    delete xmlList[i];
}

thanks peter, that using a literal delete... 
 
waht if you do delete via reference...  
 
e.g. node:XMLNode = xml.tagName["@id=3"];
 
if you delete node you've you tried to delete the new reference... how
do you delete the tag with an id attribute of 3?

I'm trying to find the most correct and efficient syntax to find nodes
with a particular attribute value and remove them from an xml document..


suppose my xml is :

<code>
<response>
<status-code>0</status-code>
<status-message><![CDATA[ The call was successful ]]></status-message>
<recipients>
<recipient id="5" firstName="John"
lastName="Smith">[EMAIL PROTECTED] <mailto:john%40blah.com> </recipient>
<recipient id="6" firstName="firstName"
lastName="lastName">[EMAIL PROTECTED] <mailto:chuck%40blah.com>
</recipient>
<recipient id="23" firstName="grant"
lastName="davies">[EMAIL PROTECTED] <mailto:grant%40blue.com> </recipient>
<recipient id="24" firstName="fool"
lastName="me">[EMAIL PROTECTED] <mailto:grant%40fool.com> </recipient>
<recipient id="25" firstName="frick"
lastName="frack">[EMAIL PROTECTED] <mailto:frick%40fool.com> </recipient>
<recipient id="26" firstName="grant"
lastName="davees">[EMAIL PROTECTED] <mailto:firday%40nowhere.com>
</recipient>
</recipients>
</response>
</code>

And I want to find recipients with an id of 6 and 23 and remove them
from the xml... What is the syntax for this?

I can find those nodes into an XMLList fine... Its removing them I'm
having fun with..

Cheers,
Grant
