Looks like it's the other way around: concat() can take xs:anyAtomicType, but string-join() requires a sequence of strings.
concat(1,2,3) => "123" Whereas: string-join((1,2,3),"") => (err:XPTY0004) fn:string-join((1, 2, 3), "") -- arg1 is not of type xs:string* Evan Lenz Software Developer, Community MarkLogic Corporation Phone +1 360 297 0087 email [email protected]<mailto:[email protected]> web developer.marklogic.com<http://developer.marklogic.com/> From: Jason Hunter <[email protected]<mailto:[email protected]>> Reply-To: General MarkLogic Developer Discussion <[email protected]<mailto:[email protected]>> Date: Fri, 10 Jun 2011 15:57:31 -0700 To: General MarkLogic Developer Discussion <[email protected]<mailto:[email protected]>> Cc: General MarkLogic Developer Discussion <[email protected]<mailto:[email protected]>> Subject: Re: [MarkLogic Dev General] output PDF from MarkLogic? It's been a while but I think I did that because concat() won't accept non-string argument types.

FYI, as a MLJAM user you don't have to do any Java coding to use FOP. The jam-utils.xqy has a function that does it for you. (:~ : Returns a PDF generated from the given XSL-FO element using the Apache : FOP 0.92 engine. : : Depends on jam:start() having previously been called. : : @param $xslfo The XSL-FO element to render as PDF : @return A binary() node holding the generated PDF document :) define function jamu:fop( $xslfo as element() ) as binary() If people write other useful functions like that, send them my way and I'll incorporate them into the utils package. Which reminds me, on my todo list, but someone else could easily beat me to it, is optimizing MLJAM to use MarkLogic Server's somewhat recent functionality to send and accept a raw binary POST body -- which should be a performance optimization compared to encoding/decoding the binary as a string as MLJAM does today. -jh- On Jun 10, 2011, at 5:08 AM, Lee, David wrote: Along the lines of the other comments ... What I use in production is a local tomcat server running the xmlsh servlet. <http://www.xmlsh.org/EmbeddingServlet>http://www.xmlsh.org/EmbeddingServlet Then from MarkLogic I package all the files needed for a PDF (including the source XML, as well as all images) into a ZIP stream, base64 encode it and POST it to an xmlsh servlet. The servlet then unencodes, unzips the files, uses XSLT to produce FOP then Apache FOP to produce a PDF. It then sends back the PDF to MarkLogic which then pushes it out to the client with the right Content-Type for PDF. This allows dynamic generation of PDF from a ML hosted application, entirely scripting based (only a few lines scripting of code on both ends). This is architecturally similar to the MLJAM solution but doesn't require any java coding. ---------------------------------------- David A.

Is there a library for outputting PDF files from MarkLogic? I found plenty of information about converting PDF to XML, but what about the other way around?
