I agree that if there was a selectText type method where you pass in an
xpath where you expect only one (or the first) resulting text value
would be great.

That's using Flash's XML object with XPath to grab the node value -
sure
that works, and is good for nodes with CDATA, but overly complex -
wrapping String() around it is easier. I was wondering just about the
XPath implementation and why it doesn't return a native string, thanks
though.

Been using xfactorstudio's Xpath classes with great success.
However, I
have found an odd thing - sometimes I have to cast what I
thought
was
already string, to a String in order for a V2 component to
accept
the
value. For example,
**This does not work:
var thisVideo:String = XPath.selectNodes("content_xml",
"thecontentpath/@videoUrl");
video_mc.mediaPlayer.setMedia(thisVideo);//does not work
Even though no compiler errors and a trace on the var
"thisVideo"
traces the proper "string" (media/video/Welcome.flv) - or what I
thought
was a string, the video in the MediaPlayback component does not
play.---
**So instead, when casting to String first, this works:
var thisVideo:String = String(XPath.selectNodes("content_xml",
"thecontentpath/@videoUrl"));
video_mc.mediaPlayer.setMedia(thisVideo);.//works
Why? What type of object was the Xpath value before I cast it
to
a
string? This makes sense for numbers in an XML file, but for
Strings???
The kicker is I can send other XPath values I don't cast to
strings
first to text fields, textAreas, and they show up fine. So is
it
something quirky with V2 components as well?
Thanks.

RE: [Flashcoders] Out of curiosity, XPath and String Datatype Oddity
Very Interesting - thank you. I've had a hard time finding this kind of documentation. At least some that is readable. The w3c pages are pretty over-spec'd and impossible to me for the most part. Interesting to have to open the class files to find out what you can do. Thanks again!

Re: [Flashcoders] Out of curiosity, XPath and String Datatype Oddity
Hmm. I now see what you mean. Maybe when you pass the value without
casting it in the "raw", some V2 components such as textArea etc, does
an auto cast toString and therefore can deal with it but the
MediaPlayback component is expecting a proper String and doesn't no
what to grab it if you pass MyVar[0].
As always I need to warn ya I might be talking out of my ass here :)

Re: [Flashcoders] Out of curiosity, XPath and String Datatype Oddity
Hi Jason,
AFAIK, XPath.selectNodes() returns an Array.
/**
10 *selectNodes
11 *
12 *returns an array of nodes that match the given XPath
13 *expression using the the XMLNode (context) as the
14 *starting context for the expression.
15 *
16 *This is the description
17 *@param (XMLNode)context
18 *@param (String)XPath expression
19 *@return (Array) matching nodes
20 */
21 static function selectNodes(context,path:String):Array{
22 return XPathParser.parseQuery(context,path)
23 }

RE: [Flashcoders] Out of curiosity, XPath and String Datatype Oddity
Hi Jason,
I've noticed simliar behavior but I think it's just in how you are using
it. Generally I think Xpath will return an array of XMLNode types
unless you grab a small enough piece of information. If you look in the
class files you can also use selectNodesAsString. This will force all
your returned data to be strings.
Unfortunately I myself just started using Xpath and I love it...so I
help this helps or points you in the right direction maybe someone else
can shed more light.
Regards,
-Ralph

Subject: [Flashcoders] Out of curiosity, XPath and String Datatype
Oddity
I'm asking this more out of curiosity than necessity, but the responses
to this thread may help be avoid some headaches in the future.
Been using xfactorstudio's Xpath classes with great success. However, I
have found an odd thing - sometimes I have to cast what I thought was
already string, to a String in order for a V2 component to accept the
value. For example,
**This does not work:
var thisVideo:String = XPath.selectNodes("content_xml",
"thecontentpath/@videoUrl");
video_mc.mediaPlayer.setMedia(thisVideo);//does not work
Even though no compiler errors and a trace on the var "thisVideo"
traces the proper "string" (media/video/Welcome.flv) - or what I thought
was a string, the video in the MediaPlayback component does not play.---
**So instead, when casting to String first, this works:
var thisVideo:String = String(XPath.selectNodes("content_xml",
"thecontentpath/@videoUrl"));
video_mc.mediaPlayer.setMedia(thisVideo);.//works
Why? What type of object was the Xpath value before I cast it to a
string? This makes sense for numbers in an XML file, but for Strings???
The kicker is I can send other XPath values I don't cast to strings
first to text fields, textAreas, and they show up fine. So is it
something quirky with V2 components as well?
Thanks.
