The closest thing to a map I've found in XSLT is <xsl:key > -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Erik Zander Sent: Thursday, July 31, 2014 4:16 AM To: MarkLogic Developer Discussion Subject: Re: [MarkLogic Dev General] XSLT check if result document has been created
Hello Mike Yes to use a map would be ideal, and actually one of my first thoughts however upon googling for maps and xslt I got the impression that XSLT doesn't have maps, is that the case? If so I would have to write my own map which I admit I haven't yet figured out as XSLT is declarative... Once or twice I miss java... Anyway thanks for pointing out a direction :) Regards Erik -----Ursprungligt meddelande----- Från: Michael Blakeley [mailto:[email protected]] Skickat: den 29 juli 2014 20:17 Till: MarkLogic Developer Discussion Ämne: Re: [MarkLogic Dev General] XSLT check if result document has been created If you want to skip the duplicates, one common pattern is to track them using a map. You could also use distinct-values, but a map can be more efficient. let $m-seen := map:map() for $i in $list let $key := $i/@id/string() (: Or some other expr based on $i :) let $is-duplicate := map:contains($m-seen, $key) let $_ := if ($is-duplicate) then () else map:put($m-seen, $key, 1) where not($is-duplicate) return $i (: Or do other processing on $i :) The map starts empty. While processing each item we check to see if it already has a map entry. If it does, we consider it a duplicate and do nothing. Otherwise we add it to the map and finish processing it. So if there are two or more items with the same @id value, only the first one will be processed. Translating this logic into XSLT is left as an exercise. The logic is the same but you'd use xsl:variable elements, etc. -- Mike On 29 Jul 2014, at 03:31 , Erik Zander <[email protected]> wrote: > Thank you Ryan and Mary > > Sadly it didn't work as I wished for, I still get duplicate uris which is > what the if statement was introduced to remove.. > XSLT-DUPRESULTURIS: (err:XTDE1490) <xsl:result-document href="out/{ > $id }.xml" method="xml" indent="yes"> </xsl:result-document> -- Two > final trees cannot have the same URI: > out/36CD63C6006FE011A8EE9FEB54B1132A.xml > > I have not yet understood completely in what ways it's possible to read and > manipulate the result tree in xslt, if I only could address that I would be > able to see if a specific id was in the result tree and then not process. > But as it stands now I think I have to rethink how I can make sure to only > process each image once even thou its reoccurring in the source xml. > Thanks anyway > /Erik Zander > Från: Ryan Dew [mailto:[email protected]] > Skickat: den 28 juli 2014 17:20 > Till: MarkLogic Developer Discussion > Ämne: Re: [MarkLogic Dev General] XSLT check if result document has > been created > > I believe you should be able to do something like the following to get what > you want: > > <xsl:template match="//db:informalfigure[descendant::db:imagedata and > @role='figure']"> > > > > <xsl:variable name="curImage" > select="substring-after(.//@fileref,'/')"/> > > <xsl:variable name="id" > select="$imageMetaData//image[name=string-join(($curISBN,$curImage),'/')]/id"/> > <xsl:if > test="not(doc-available(xdmp:resolve-uri(string-join(('out/',$id,'.xml'),''),xdmp:node-uri(.))))"> > <!--This check fails, am I doing it incorrectly or is it the way xslt > processes document that makes it hard to check if the id have been > encountered before?--> > > <xsl:result-document method="xml" href="out/{$id}.xml" > indent="yes"> > > > On Mon, Jul 28, 2014 at 9:08 AM, Mary Holstege <[email protected]> > wrote: > > I think you may be running afoul of URI resolution. > Since the URI you are giving to doc-available is a relative URI, it > will be resolved relative to the static base URI, which per XSLT is > the URI of the stylesheet itself. > > //Mary > > On Mon, 28 Jul 2014 07:58:04 -0700, Erik Zander > <[email protected]> wrote: > > > Hi All > > > > I'm working on an xslt transform where I'm extracting data about > > images from a document and put that data into result document, It > > all works fine except for when the same image occurs more than once > > as I then get conflicting uris, > > > > my code looks like this > > <xsl:template match="//db:informalfigure[descendant::db:imagedata > > and @role='figure']"> > > > > > > > > <xsl:variable name="curImage" > > select="substring-after(.//@fileref,'/')"/> > > > > <xsl:variable name="id" > > select="$imageMetaData//image[name=string-join(($curISBN,$curImage),'/')]/id"/> > > <xsl:if > > test="not(doc-available(string-join(('out/',$id,'.xml'),'')))"> > > <!--This check fails, am I doing it incorrectly or is it the way > > xslt processes document that makes it hard to check if the id have > > been encountered before?--> > > > > <xsl:result-document method="xml" href="out/{$id}.xml" > > indent="yes"> > > > > Ideally I would like to be able to check if the result document have > > been created or not and after that decide if I want to update it > > with more information or just leave it be. > > > > Would appreciate any help on the subject > > > > Best regards > > Erik > > > -- > Using Opera's revolutionary email client: http://www.opera.com/mail/ > _______________________________________________ > General mailing list > [email protected] > http://developer.marklogic.com/mailman/listinfo/general > > _______________________________________________ > General mailing list > [email protected] > http://developer.marklogic.com/mailman/listinfo/general _______________________________________________ General mailing list [email protected] http://developer.marklogic.com/mailman/listinfo/general _______________________________________________ General mailing list [email protected] http://developer.marklogic.com/mailman/listinfo/general
