Siggi, I have very limited knowledge of XPath/XQuery. I don't know why your selectPath() call doesn't work. It seems right. Can you say what version of XMLBeans you are using (2.0? 2.1? latest svn?) and also what version of Saxon? I believe that $this works as advertised with the BEA XQuery engine, but I'm not sure about Saxon. Again, I know very little XQuery, but maybe you could try something along the lines of
let $cur := . return //[EMAIL PROTECTED]/@id] if $this is not working. - Wing Yew ________________________________ From: Siegfried Baiz [mailto:[EMAIL PROTECTED] Sent: Thursday, March 16, 2006 12:29 AM To: [email protected] Subject: Re: selectPath with FilterExpression using $this Hello Wing Yew, yes, that's what I'm looking for. Do you have any idea, why xo.selectPath("//[EMAIL PROTECTED]/@id]") doesn't work (for my XmlObject xo with ID-Attribute 'id')? Or is there some better why to receive all nodes (with idRef-Attribute) refering to my node xo? - thanks for your help - Siggi Wing Yew Poon wrote: Siggi, I think you're right. I guess what you need is a variable bound to the node represented by the XmlObject that you're executing the selectPath() from. "$this" is supposed to be that. - Wing Yew -----Original Message----- From: Siegfried Baiz [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 15, 2006 3:09 AM To: [email protected] Subject: Re: selectPath with FilterExpression using $this For the Expression xo.selectPath("//[EMAIL PROTECTED]/@id]" <mailto://[EMAIL PROTECTED]/@id]> ) I get an empty result-array. Doesn't the left- and the right-hand-side of that filter-expression always refer to the same node, which would mean, that the xpath-engine tries to select any nodes with the two attributes @idRef & @id having the same value? - Siggi - Siggi, can you try xo.selectPath("//[EMAIL PROTECTED]/@id]" <mailto://[EMAIL PROTECTED]/@id]> ); and see if that works? - Wing Yew -----Original Message----- From: Siegfried Baiz [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 14, 2006 10:11 AM To: [email protected] Subject: selectPath with FilterExpression using $this Hello, for a given XmlObject xo with an ID-Attribute 'id', I've tried to launch the following xpath-expression: xo.selectPath("//[EMAIL PROTECTED]/@id]") in order to get all nodes (with idRef-Attribute) refering to my node xo. Unfortunatlly this expression seems not to work. I always get an java.lang.ArrayIndexOutOfBoundsException from the underlying net.sf.saxon.expr.XPathContextMajor.setLocalVariable(XPathContextMajor. j ava:213) At http://xmlbeans.apache.org/docs/2.0.0/guide/conSelectingXMLwithXQueryPa t hXPath.html I found the following notice: "Notice in the query expression that the variable $this represents the current context node (the XmlObject that you are querying from). In this example you are querying from the document level XmlObject." After reading that sentence I've been thinking, that $this is somehow similar to "curent()" in XSLT, but maybe a got the meaning wrong. Does anyone know whats the problem here rsp. is there a better way to accomplish the same thing? Thanks a lot, Siggi --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] _______________________________________________________________________ Notice: This email message, together with any attachments, may contain information of BEA Systems, Inc., its subsidiaries and affiliated entities, that may be confidential, proprietary, copyrighted and/or legally privileged, and is intended solely for the use of the individual or entity named in this message.
