Now use XML tag names instead of XML.childNodes
|
|
If you are accessing XML tags using childNodes, try using this code. It creates dynamic properties that allow you to access the XML tags in a more human readable form such as myXML.catalog.page.item[3].price
Here's an example including the XML and flash source code:
XML Example:
<?xml version="1.0" encoding="iso-8859-1" ?> <PRODUCE> <FRUIT> <APPLE> <KIND>Delicious</KIND> <COLOR>Red</COLOR> <PRICE> <AMOUNT>.79</AMOUNT> <PER>pound</PER> </PRICE> </APPLE> <PEAR> <KIND>Golden</KIND> <COLOR>yellow</COLOR> <PRICE> <AMOUNT>.99</AMOUNT> <PER>pound</PER> </PRICE> </PEAR> </FRUIT> </PRODUCE> // DESCRIPTION: The following routines reparse the XML structure and add routines that allow
// access to nodes to be much more human readable.
//
// EXAMPLE: Instead of using: myXML.firstChild.childNodes[5].childNodes[3].description.firstChild.nodeValue;
// Now you can use: myXML.catalog.page[5].item[3].description.firstChild.nodeValue;
//
// NOTES: Since the XML structure is parse a second time, there may be a performance hit. On a
// - 1G machine, I did not notice any with roughly 100 elements.
// - The structure created by XML.parseXML is preserved, these routines merely enhance it.
// - XML.parseXML MUST be called before extendXML.
// - This routine does NOT cleanup after itself (beware of reusing the XML object).
// - Also, it has only been tested for XML source (not HTML etc.).
// - The following can NOT be used for generated XML tags:
// attributes, childNodes, contentType, docTypeDecl, firstChild, ignoreWhite,
// lastChild, loaded, nextSibling, nodeName, nodeType, nodeValue, onLoad,
// parentNode, previousSibling, status, xmlDecl, nodeFuncs (there may be others).
// - Read below about how DUPLICATE TAGS are handled.
// - It has been reported to me that attributes work similar to the following:
// myXML.catalog.page[5].item.attributes.description;
//
// AUTHOR: Mark Britt ( CreateN )
//
// CHANGE LOG: If you make any improvements/bug fixes, I would appreciate a copy, thanks : )
//
XML.prototype.traverseNodes = function ( node ) {
var i = 0;
var children = node.childNodes; //required for performance issues (interpreter recalling childNodes)
if ( node.nodeFuncs == undefined ) { node.nodeFuncs = new Object; } // add array for addProperty functions
while ( children[i] ) {
// DUPLICATE TAGS: We need to handle childNodes that contain duplicate nodeName entries
// The following works only if all nodeNames are equal for the entire childNodes list
// this is NOT a final solution, modify as needed
var flag = true;
if ( children.length > 1 && children[0].nodeName == children[1].nodeName ) {
// for now, we assume all children are equal
if ( i == 0 ) {
// Only addProperty for the first node
node.nodeFuncs[0] = function () { return node.childNodes; };
} else {
flag = false;
}
} else {
node.nodeFuncs[i] = function () { return this.childNodes[arguments.callee.index]; };
// saving 'index' allows the interpreter to find the node when calling the 'nodeFunc'
node.nodeFuncs[i].index = i; // save the node index with the associated function
}
if ( flag == true ) {
// addProperty for each node except duplicate nodes
if ( children[i].nodeName.length && node.addProperty( children[i].nodeName, node.nodeFuncs[i], null ) ) {
//trace ("Property:"+child.nodeName+" added");
}
}
if ( children[i].childNodes.length > 0 ) {
this.traverseNodes( children[i] );
}
i++;
}
//trace("traverseNodes");
}

this.traverseNodes( this );
//trace("extendXML");
}
}

if ( src == undefined ) {

// OR this.traverseNodes( this ); and eliminate extendXML
this.loaded = true;
this.onLoad( true );
}
}
function myOnLoad(success) {
if (success) {
trace ("Load succeeded!");
// EXAMPLE Access to the new XML properties
var result1 = this.produce.fruit.apple.price.amount.firstChild.nodeValue;
// result1= .79
var result2 = this.produce.fruit.apple.price.per.firstChild.nodeValue;
// result2= pound
} else {
trace ("Load failed!");
}
}

myXML.load( "file.xml" );

Pretty Print / Structured Print
|
|
XML.prototype.prettyPrint = function(spacer) {
spacer = (spacer == undefined) ? "\t" : spacer;
var xml_str = this.toString();
var open, closed, tabs, output, node_str, eol;
output = "";
open = xml_str.indexOf("<", 0);
var tab_next = false;
while (open != undefined and open != -1) {
if (open != -1) {
closed = xml_str.indexOf(">", open+1);
node_str = xml_str.substring(open, closed+1);
if (tab_next) {
tabs++;
tab_next = false;
}
if (node_str.indexOf("/") == 1) {
tabs--;
} else if (node_str.lastIndexOf("/") != node_str.length-2) {
tab_next = true;
}
ts = "";
for (var j = 0; j<tabs; j++) {
ts += spacer;
}
if (open == last_closed+1) {
eol = "\n"+ts;
} else if (open>0) {
eol = xml_str.substring(last_closed+1, open);
}
output = output+eol+node_str;
}
open = xml_str.indexOf("<", open+1);
last_closed = closed;
}
return output;
};
//This is a fast "pretty print" function for the XML object.
//It basically just prints out the XML object in a structured fashion with tabbed indents.
//usage: trace(myXMLObj.prettyPrint()); - for tabbed indents
//or: trace(myXMLObj.prettyPrint(" ")); - for tabbed custom-specified indents
