Hi James, I'm interested in this topic and I have an question about the namespace for the attribute:
At the data loading time, Dev declared namespace as "http://www.w3.org/1999/xhtml xdmp:document-insert("/content/htmlchk66.html", <html xmlns="http://www.w3.org/1999/xhtml"; xml:lang="en" lang="en"> <body> <meta name="org" content="abc-de" /> <meta name="product" content="electronics" /> <meta name="education" content="school" /> <meta name="test" content="answer123" /> </body> </html>) My understanding for namespace is: if you declare the namespace, unless you change it or it goes out of the scope, all the following elements and attributes belong to this namespace. But you mentioned that the attributes in Dev's data does not have any namespace, I think I misunderstood the concept. Can you explain it more? Thanks, Helen >>> "James Clippinger" <[EMAIL PROTECTED]> 08/14/07 5:41 PM >>> Dev, the syntax you used would associate the prefix "html" with the XHTML namespace; you could use it like this: declare namespace html="http://www.w3.org/1999/xhtml"; cts:search(xdmp:directory(('/'),"infinity"), cts:and-query((cts:element-attribute-value-query(xs:QName("html:meta"), xs:QName("name"), "org"),cts:element-attribute-value-query(xs:QName("html:meta"), xs:QName("content"), "abc-de")))) Now, you could use the "default element namespace" syntax to set the default: default element namespace="http://www.w3.org/1999/xhtml"; cts:search(xdmp:directory(('/'),"infinity"), cts:and-query((cts:element-attribute-value-query(xs:QName("meta"), xs:QName("name"), "org"),cts:element-attribute-value-query(xs:QName("meta"), xs:QName("content"), "abc-de")))) However, this will return no results in your example, because xs:QName() will, when given an unprefixed string, return QNames in the default element namespace. This is the right thing for the QNames being used as elements, but it causes the attribute QNames not to match since they are in the no namespace. This version would work: default element namespace="http://www.w3.org/1999/xhtml"; declare namespace no-namespace="" cts:search(xdmp:directory(('/'),"infinity"), cts:and-query((cts:element-attribute-value-query(xs:QName("meta"), xs:QName("no-namespace:name"), "org"),cts:element-attribute-value-query(xs:QName("meta"), xs:QName("no-namespace:content"), "abc-de")))) I think the html-prefix form is more intuitive than this one, but it is legal XQuery and will work just fine.

I couldn't understand, why declaring default namespace is not working in this case (declare namespace html = "http://www.w3.org/1999/xhtml";). Is it because of xhtml namespace? Thanks, Dev On 8/14/07, James Clippinger <[EMAIL PROTECTED] > wrote: Dev, you need to include the XHTML namespace in the element QNames you create for use in the cts:search() if you want the query to match those elements. This would work: cts:search(xdmp:directory(('/'),"infinity"), cts:and-query((cts:element-attribute-value-query(fn:QName(" http://www.w3.org/1999/xhtml <http://www.w3.org/1999/xhtml> ", "meta"), xs:QName("name"), "org"),cts:element-attribute-value-query(fn:QName(" http://www.w3.org/1999/xhtml <http://www.w3.org/1999/xhtml> ", "meta"), xs:QName("content"), "abc-de")))) Note that the attribute QNames don't require namespace URIs because, having not been prefixed in the original source, they are in the no namespace. If you wanted to use the fn:QName() function for consistency, this form also works: cts:search(xdmp:directory(('/'),"infinity"), cts:and-query((cts:element-attribute-value-query(fn:QName(" http://www.w3.org/1999/xhtml <http://www.w3.org/1999/xhtml> ", "meta"), fn:QName("", "name"), "org"),cts:element-attribute-value-query(fn:QName(" http://www.w3.org/1999/xhtml <http://www.w3.org/1999/xhtml> ", "meta"), fn:QName("", "content"), "abc-de")))) Regards, James ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Devadoss P Sent: Tuesday, August 14, 2007 4:49 PM To: General Mark Logic Developer Discussion Subject: Re: [MarkLogic Dev General] xhtml loading question James, This is the query used to load the document, xdmp:document-insert("/content/htmlchk66.html", <html xmlns="http://www.w3.org/1999/xhtml " xml:lang="en" lang="en"> <body> <meta name="org" content="abc-de" /> <meta name="product" content="electronics" /> <meta name="education" content="school" /> <meta name="test" content="answer123" /> </body> </html>) and my cts query is cts:search(xdmp:directory(('/'),"infinity"), cts:and-query((cts:element-attribute-value-query(xs:QName("meta"), xs:QName("name"), "org"),cts:element-attribute-value-query(xs:QName("meta"), xs:QName("content"), "abc-de")))) This query returns result, if I load document without xmlns.
