Re: [Flashcoders] XPathAPI problems with wildcard searches
I suspect you're expecting similar results to using XSLT where you xsl:template match=blah statement bearing in mind this only works when you use the xsl:apply-templates /, which crawls the tree applying the xpath statements. Remember all you statements are relative to the root node that you pass in (in your example is xml) To my knowledge the XPathAPI wont support what you want, you're need to do some kind of recursion May be worth looking at the other XPath library, cant remember where it is, but a quick google will point you in the right direction i'm sure...

[Flashcoders] XPathAPI problems with wildcard searches
I've been having problems with the xpathapi. I've been trying to do a
wildcard search and according to all the documentation it's supported
yet even simple straight forward search isn't working. Can anyone help?
Example :
code
import mx.xpath.XPathAPI;
x = new XML(test thing='boo'items name='blah'item foo='bar'/item
foo='blah'//items/test);
r = XPathAPI.selectNodeList(x,/*/item);
for (var i in r) {
trace(r[i]);
}
/code
Thanks in advance,
Lori-

RE: [Flashcoders] XPathAPI problems with wildcard searches
x = new XML(test thing='boo'items name='blah'item foo='bar'/item foo='blah'//items/test); r = XPathAPI.selectNodeList(x,/*/item); If I understand correctly, that search would not find anything, because item is not a child of test, but rather of items. If I'm reading your XPath expression correctly, you would find /items/item, but not /test/items/item. Valid alternative expressions would be //item, /test/*/item, /*/*/item.

Re: [Flashcoders] XPathAPI problems with wildcard searches
The reason I am trying to do the wildcard search is because I have nodes of the same name at different levels and I need them all. So giving a specific path wouldn't give me all of the nodes I need. That's not what your select says, the * wildcard only selectes children. /*/item = select all item nodes which are one level below the root (grandchildren of the context node). //item = select all item nodes on any level of the document (all descendants of the context node). Yes * and / are mathematical operators but in the context of a xpath search they are used as you expect if you were doing a regex search... which also supports the * and / If you read the W3C spec, they specifically mention this ambiguity and the problems that can arise. It is a known issue with wildcards in XPath, and you should not expect it to behave the same way as any particular implementation of RegEx. What I am attempting to do is get all the node nodes by doing r = XPathAPI.selectNodeList(myXML,/*/node); What you want is: r = XPathAPI.selectNodeList(myXML,//node); ryanm ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
