Diego, Here is a starting point. There are probably bugs, it is bloated, and it is not completely tested, however, it is a starting point.
A final version of this, along with some actual example code, error handling and other dynamic tools will eventually be available in a devnet article. Used as follows: import net.digitalprimates.utils.E4XParser; var parser:E4XParser; parser = new E4XParser(); var returnXML:XMLList; //Use parser.evaluate( data:XML, expression:String ); returnXML = parser.evaluate( myXML, '..item.(@id==2)..price' ); If you find a bug, let me know off list. BTW, thanks on this and future releases also go to Alex Harui who started this pet project before I. (Although none of the blame for the bad code that currently permeates it) http://www.digitalprimates.net/src/e4x.zip --Mike --- In flexcoders@yahoogroups.com, "Diego Guebel" <[EMAIL PROTECTED]> wrote: > > Hi all, > I'm wondering if there is any method to "apply" an e4x expression passed > as a string to an xml. > For example I have this variable: > private var sourceXML:XML = <order> > <book ISBN="0942407296"> > <title>Baking Extravagant Pastries with Kumquats</title> > <author> > <lastName>Contino</lastName> > <firstName>Chuck</firstName> > </author> > <pageCount>238</pageCount> > </book> > <book ISBN="0865436401"> > <title>Emu Care and Breeding</title> > <editor> > <lastName>Case</lastName> > <firstName>Justin</firstName> > </editor> > <pageCount>115</pageCount> > </book> > </order> > > and a method like this: > > private function testExpression(s:String):void > { > // somehow, I want to apply that string as e4x expression to the xml > result_txt.text = sourceXML.apply(s); > } > > Any clue? > Thanks in advance. > Diego. > -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!
