Deleting XML Element

[Sleeve]

Can't really find anything on this and I'm having a heck of a time.

I thought I could delete an element by passing a XML reference to the delete(XML) method.

var xml : XML = new XML(<column>
    <row type='header' font='Verdana' size='10'>Title</row>
    <row font='Verdana' size='12'>item1</row>
    <row font='Verdana' size='10'>item2</row>
</column>)

then delete it using this

var ref : XML = <row font='Verdana' size='12'>item1</row>;
delete (xml.ref);

Any help on this?

xml.ref finds the ref nodes in the xml. Instead what you can do is use

delete xml.row[1];

Yes however, the XML data is dynamically created and it may not be possible to know the element number. I could iterate through the XML object, convert each element to an XML string and compare it to 'ref' but I had hoped I could avoid this.

Looks like I'll have to find some other way.

if all you have is the string representation of the node to be deleted, that might be the only way.

So, maybe you can provide some clarity on how to delete an XML node by passing an XMLList reference as the operand.

I keep getting this error: TypeError: Error #1119: Delete operator is not supported with operand of type XMLList. Yet in the documentation, it states "When used with an XMLList operand, the result of the delete operator is always true because the XMLList operand always refers to a valid (though possibly empty) XMLList object."

This will delete the row for you. I would have to see more code to know how you got the target row as an XMLList.

deleteColumnRow( <row font='Verdana' size='12'>item1</row> );

private function deleteColumnRow
    ( avXml:XML )
    :void
{
    for( var lvIndex:int = 0; lvIndex < xml.row.length(); lvIndex++ )
    {
        if( xml.row[lvIndex] == avXml )
        {
            delete xml.row[lvIndex]
            break;
        } // if
    } // for each
    
} // deleteColumnRow

delete xml.row.(@size == "12")[0];

Simply add "[0]" to the end of the where clause if you are narrowing down the list to one element. Although in this case, I don't know if the 12 is a good unique identifier, but I think you get the idea.
