Doesnt XPath.selectNodes(myxml, "pathtocontent/text()"); return the text
value as well?

Could it be because the Xpath may return either a string or an array
depending on how you structure your query?
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.

Maybe something like this may help?
myText=XMLNode((XPath.selectNodes(myxml,"myNodePath/mynode()")[0])).no
de
Value;

How do you use Xpath to return node values then?

Hi Jason,
AFAIK, XPath.selectNodes() returns an Array.
<snippet from the docs>
/**
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 }

</snippet from the docs>
HTH,

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.
