Serialize to XHTML 5?
by Andreas Mixich 04 May '19

04 May '19

Hi, let $doc := <html><head><title>Example Title</title></head><body><p>Paragraph</p></body></html> return serialize($doc, map{"method":"xhtml", "version":"5.0"}) results in [SESU0013] Invalid 'version' value '5.0'; must be one of: 1.0,1.1. How can I make sure, I get the <!DOCTYPE html> and all empty elements closed? As far as I remember, the W3C has ratified an XHTML serialization of HTML5 as legit part of the HTML5 spec (replacing the "Polyglot HTML5" term). -- Minden jót, all the best, Alles Gute, Andreas Mixich

by chandra Sekhar 03 May '19

Hai Basex Team, We have already created one collection after that adding xmls to that collection, This process is taking much time and the total xml are nearly 2 lakhs. How to get performance to add xmls to collections. We are using basex(version 7.9) client server architecture with java technology to perform creating collection and adding xmls to collection. below two ways we are using to add the xml to collection 1) Using FileInputStream(When file size is small,less than 1 gb) 2) Using ADD command(While file size is large,greater than 1 gb)

A Tail Call, that runs (not) if different numeric values are being used as parameter
by Andreas Mixich 02 May '19

02 May '19

Hi, as far as I have understood, a tail call function must end with the call to itself, after it has calculated all the values and, upon recursive call, no operation must be open in the calling instance of the function. This is why the following case confuses me. The function, as shown, produces a stack overflow and I get the hint to do tail recursion. However, if I swap just the expressions (after 'then' and 'else') in lines 13 and 14, the function computes. Now I would have thought, that it would break, because I recurse within another function, that is still open ('concat()') and thus must return to the calling function after recursion, but, interestingly, the swap of the expressions after the 'then' and 'else' statements on lines 13 and 14 do not error out with a stack overflow, in spite 'concat()' still being open. Both cases produce an integer. Also, advice would be welcome, on how I can solve this. Thank you very much. 1 declare function local:word-wrap( 2 $string as xs:string, 3 $width as xs:integer) 4 5 { 6 let $t := normalize-space($string) 7 return 8 if (string-length($t) < $width or string-length($t) = $width) 9 then $t 10 else 11 let $idx := 12 if (matches($t, "\s")) 13 then functx:index-of-string-last(substring($t, $width), " ") 14 else $width 15 return 16 concat( 17 string:trim-right(substring($t, 1, $idx)), 18 out:nl(), 19 local:word-wrap(string:trim-left(substring($t, $idx)),$width) 20 ) 21 }; 22 23 local:word-wrap("This is a very long line of text. It goes well beyond 80 (eighty) characters in width. Therefore we need a word wrap function, which we test in here.

Hi, in 9.2 web admin I get an HTTP 400 with any file upload: Stopped at D:/BaseX92/webapp/dba/files/file-upload.xqm, 23/10: [XPTY0004] Cannot convert empty-sequence() to map(xs:string, xs:base64Binary): (). The file seems to be sent, but $files is empty. Is this a bug?
