xslt and xlink question
Locked
 
|
I am consuming a webservice that returns data like the example below, which has xlink attributes for most of the elements. I find that I am unable to use this data, all my xpath expressions like <xsl:value-of select="/feeds/feed/@id" /> return empty content, whereas, if I remove the xlink attribute, I get expected values. Is this normal behavior for xslt? Is it evaluating the xlink attribute in some way? Should I go ahead and pre-process the xml to remove the xlink attributes? Thanks for any insights, Hank <feeds xlink:href="http://tpm.nees.ucsb.edu/feeds"> <feed id="Garner_Valley" xlink:href="http://tpm.nees.ucsb.edu/feeds/Garner_Valley"> <stream id="High-Res" xlink:href="http://tpm.nees.ucsb.edu/feeds/Garner_Valley/High-Res"> <video-box-size>large</video-box-size> <max-connection-length>240</max-connection-length> <jpeg xlink:href="http://tpm.nees.ucsb.edu/feeds/Garner_Valley/High-Res/jpeg"></jpeg> <mjpeg xlink:href="http://tpm.nees.ucsb.edu/feeds/Garner_Valley/High-Res/mjpeg"> ....

Hi,
Under 2.8, the following worked: <xforms:bind nodeset="/form/document/vr:Resource/vr:curation/vr:creator/vr:name/@ivo-id" type="xs:anyURI" constraint="string-length(.) = 0 or matches(., "ivo://[\w\d][\w\d\-_\.!~\*'\(\)\+=]{2,}(/[\w\d\-_\.!~\*'\(\)\+=]+(/[\w\d\-_\.!~\*'\(\)\+=])*)?")"/> With 3.0beta3, I have to change: {2,} to 2, to get this to work - is this a bug?

Actually, the problem seems related to its own namespace, not the xlink namespace or attributes.

This kind of question pops up frequently on the XSLT list at MulberryTech (http://www.mulberrytech.com/xsl/xsl-list). Post this on that list and you will get a quick, authoritative reply.

Hank,
This is not normal behavior for XSLT. In fact, it strongly suggests a bug somewhere. Your <xsl:value-of /> uses an XPath location path in the "select" attribute that starts at the root node of the document (signified by the opening "/"), and then moves down the hierarchy of the document to the "feed" element node. At that point it moves onto the attribute axis and retrieves the value of the "id" attribute. All that is just fine. The "xlink:href" attribute on the <feed> element can't affect your XPath at all. That it apparently does affect it is quite strange, and it's difficult for me to think that any XSLT engine would have such a bug at this point in the life of XSLT. And, no, given the XPath you've written, there is no reason for the XSLT engine to be evaluating the xlink attribute at that point. I can't suggest what to do as far as pre-processing; it's certainly a shame to have to write a process to avoid something that should not be happening to begin with. Perhaps if I knew more I could suggest why this is happening, but I'm not sure.

Hank, have you been able to track down this issue?

The Saxon XPath engine is used, and for now it is the same used in 2.8, so there shuld not be a difference. Also, replacing "{2,}" with "2," will probably change the behavior of your regexp! -Erik -- You receive this message as a subscriber of the [hidden email] mailing list.

The issue appears to be related to the request-generator. The URL: http://nees.ucsb.edu/imageserver/gvda?set=gvda&image=img001.jpg&width=163&height=122 for example, after parsing by the request-generator yields the following, in which the query-string has been encoded. So, it is being encoded twice and this results in a "filename" that can't be used by the cache. --Hank <root> <request> <parameters> <parameter> <name>amp;height</name> <value>122</value> </parameter> <parameter> <name>set</name> <value>gvda</value> </parameter> <parameter> <name>amp;image</name> <value>img001.jpg</value> </parameter> <parameter> <name>amp;width</name> <value>163</value> </parameter> </parameters> <query-string>set=gvda&amp;image=img001.jpg&amp;width=163&amp;height=122</query-string> </request> <config xmlns:p="http://www.orbeon.com/oxf/pipeline"> <image-directory>oxf:/imageserver</image-directory> <default-quality>0.7</default-quality> <use-sandbox>false</use-sandbox> </config> <image xmlns:p="http://www.orbeon.com/oxf/pipeline"> <path>gvda/</path> <use-cache>true</use-cache> <transform type="scale"> <width/> <height/> </transform> </image> </root> ----- Original Message ----- From: "Erik Bruchez" <[hidden email]> To: <[hidden email]> Sent: Thursday, September 22, 2005 3:30 PM Subject: Re: [ops-users] xslt and xlink question > Hank, have you been able to track down this issue? > > -Erik > > Hank Ratzesberger wrote: >> >> Actually, the problem seems related to its own namespace, not the xlink >> namespace or attributes. >> >> Thanks, >> Hank >> >> >> ----- Original Message ----- From: "Hank Ratzesberger" >> <[hidden email]> >> To: <[hidden email]> >> Sent: Wednesday, September 14, 2005 8:56 AM >> Subject: [ops-users] xslt and xlink question >> >> >>> >>> I am consuming a webservice that returns data like the example below, >>> which has xlink attributes for most of the elements.
