x.attributes()[i].name()) will give you the name of the ith attribute.

 

Another syntax for this is [EMAIL PROTECTED]()

Thanks Chas, but I am trying to get the names of the attributes.  I am getting dynamic data out of a database in XML form and I need to know the attribute names from the XML.  I just want the attribute names at the parent level.  In the sample I have written I would get “id” and “task”.

 

Thanks for your help, I will definitely look at the resource you mentioned.

 

Michael

Suppose x:XML is the XML you show above. The "myChild" tags are
already accessible "as if" they were an array; for example, you can say

trace(x.myChild[0].toXMLString());

which will output

<mychild id="1.1" task="do this" tools="hammer"/>

Also, to access an attribute, you can use any of the following:

trace(x.myChild[0].attribute("id"));
trace(x.myChild[[EMAIL PROTECTED]"id"]);
trace(x.myChild[[EMAIL PROTECTED]);

all of which will output the string "1.1".

To use the XML as an array (sort of), you can use code such as:

for (i=0; i<x.myChild.length(); i++) {
trace(i+" id "+x.myChild[[EMAIL PROTECTED]);
}

x.myChild.length() returns the number of elements which are tags of
the type "myChild" (note the parens; it's ".length()", not ".length").

All this and more (e.g., the ability to only refer to myChild tags
which have the attribute tool=="hammer") can be found in the help docs
