Streaming results
by Bram Vanroy 20 Apr '18

20 Apr '18

Dear list I am curious to find out whether it is possible to stream results of a query, i.e. where a submitted query behaves as a generator. Especially for web interfaces this is useful: a user is presented with a result as soon as it is found, and doesn't have to wait for all results to be gathered. Especially useful with large databases of course. Preferably a way that works with the nodejs, PHP client but I am open to other suggestions. Thanks in advance Bram

Dagger et al. being replaced by char refs in returned XML
by Chuck Bearden 19 Apr '18

19 Apr '18

Hi all, I have loaded a large XML document (a dictionary of New Testament Greek) into its own database in BaseX 9.0. I'm using OpenJDK 1.8.0_162 under Ubuntu 16.04.4. I used the default Java parser, and I enabled the token & full text indices, but otherwise the database settings were the defaults. When I execute a particular query, I'm getting a sequence of the character reference for the carriage return ('') instead of some characters like the single & double daggers. Here is some typical output:  <entry n="ἄγε|G33"> <note type="occurrencesNT">2</note> <form> <orth>ἄγε</orth>,</form> <seg type="derivation">prop. imperat. of<ref> <foreign xml:lang="grc">ἄγω</foreign> </ref>,</seg> <sense> <gloss>come!</gloss>used as<gramGrp> <pos>adv.</pos> </gramGrp>and addressed, like<ref> <foreign xml:lang="grc">φέρε</foreign> </ref>, to one or more persons:<ref osisRef="Jas.4.13">Ja 4:13</ref>,<ref osisRef="Jas.5.1">5:1</ref> </sense> </entry> The sequence of '' char refs replace a dagger '†' (U+2020). I wonder if I'm doing something wrong, or if I've happened on a bug. Here is my XQuery: declare namespace tei = "http://www.crosswire.org/2013/TEIOSIS/namespace"; declare namespace xsi = "http://www.w3.org/2001/XMLSchema-instance"; let $coll := collection('abbott-smith.tei'), $elems := $coll//tei:seg[parent::tei:entry] return <div xmlns="http://www.crosswire.org/2013/TEIOSIS/namespace" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">{ for $elem in $elems let $entry := $elem/parent::tei:entry, $entry_lemma := $entry/@n/data(), $page_num := $elem/preceding::tei:pb[1]/@n/data(), $comment_text := concat('Page: ', $page_num, ' ; Entry: ', $entry_lemma, ' ') return ( comment {$comment_text}, $entry ) }</div> The source XML document is here: https://github.com/translatable-exegetical-tools/Abbott-Smith/blob/master/a… Thanks in advance for your guidance. All the best, Charles Bearden

Validation Module: validate:xsd-report( ) improvement
by Yitzhak Khabinsky 19 Apr '18

19 Apr '18

Hello, I am successfully using BaseX Validation Module. Along the following lines: let $xml := 'd:\Temp\CDW\HOME\id4879_BO201801_HomeSubscriberMovementFact.xml' let $xsd := 'd:\Temp\CDW\HOME\HomeSubscriberMovementFact.xsd' return validate:xsd-report($xml, $xsd, '1.1') My XML files have multi-megabyte size and lots of validation errors. In tens or hundreds of thousands of errors. Behind the scenes, Saxon validator 9.8.0.11 is running. Unfortunately, the output structure contains a repeating url attribute. The BaseX output pane cannot present all the errors. It says: "(Chopped) Results". <report> <status>invalid</status> <message level="Error" line="10" column="26" url="file:///D:/Temp/CDW/HOME/id4879_BO201801_HomeSubscriberMovementFact.xml">The content "N/A" of element <CommercialServiceCode> does not match the required simple type. Value "N/A" contravenes the enumeration facet "R60080-X00162, R60080-X00163, ..." of the type Q{http://www.millicom.com}CommercialServiceCodeType</message> <message level="Error" line="19" column="23" url="file:///D:/Temp/CDW/HOME/id4879_BO201801_HomeSubscriberMovementFact.xml">The content "TBD" of element <MovementTechnology> does not match the required simple type. Value "TBD" contravenes the enumeration facet "N/A, HFC, GPON, MMDS, FIBER, C..." of the type Q{http://www.millicom.com}MovementTechnologyType</message> <message level="Error" line="24" column="18" url="file:///D:/Temp/CDW/HOME/id4879_BO201801_HomeSubscriberMovementFact.xml">The content "-1.0000" of element <DownloadSpeed> does not match the required simple type. Value "-1" contravenes the minExclusive facet "0" of the type Q{http://www.millicom.com}DownloadSpeedType</message> <message level="Error" line="26" column="6" url="file:///D:/Temp/CDW/HOME/id4879_BO201801_HomeSubscriberMovementFact.xml">The 7th field in constraint {PK} has no value</message> ... </report> My proposal is to eliminate the repeated url attribute from the each message and elevate it to its own element just once under the root report tag. Along the following output structure: <report> <status>invalid</status> <url>file:///D:/Temp/CDW/HOME/id4879_BO201801_HomeSubscriberMovementFact.xml</url> <message level="Error" line="10" column="26">The content "N/A" of element <CommercialServiceCode> does not match the required simple type. Value "N/A" contravenes the enumeration facet "R60080-X00162, R60080-X00163, ..." of the type Q{http://www.millicom.com}CommercialServiceCodeType</message> <message level="Error" line="19" column="23">The content "TBD" of element <MovementTechnology> does not match the required simple type. Value "TBD" contravenes the enumeration facet "N/A, HFC, GPON, MMDS, FIBER, C..." of the type Q{http://www.millicom.com}MovementTechnologyType</message> <message level="Error" line="24" column="18">The content "-1.0000" of element <DownloadSpeed> does not match the required simple type.

Re: [basex-talk] Validation Module: validate:xsd-report( ) improvement
by Yitzhak Khabinsky 19 Apr '18

Hi Marco, The proposed solution is way too slow. let $xml := 'd:\Temp\CDW\HOME\id4879_BO201801_HomeSubscriberMovementFact.xml' let $xsd := 'd:\Temp\CDW\HOME\HomeSubscriberMovementFact.xsd' let $validate := validate:xsd-report($xml, $xsd, '1.1') return file:write("output.xml", copy $newvalidate := $validate modify (delete node $newvalidate//@url) return $newvalidate ) I guess delete node... is too heavy. It runs for 143 seconds. Without it just 11 seconds. The input XML file size is about 40MB. The output.xml file has about the same size. That's why I was proposing to change the default output format of the validation.

It works. But I was referring to the default behavior. The url attribute is redundant for every message element.

Hi, Last month I have been working on a R client. Results from my work are attached. The 'add, replace and store'-commands should be working but haven't been tested yet since I don't have any good example-commands at hand. I'm looking forward for comments! Ben Engbers

Hi, It seems there is an error with the collection function.

I see that in the 9.0 version the "+ button" to add a new tab is missing. I think it was very useful: can it be re-introduced in the following releases?

Multipart and charset
by Marco Lettere 16 Apr '18

16 Apr '18

Hi everyone, when parsing a multipart response we are getting from a server we need to integrate with basex raises the exception [1]. By forcing the mediatype (with override-media-type attribute) to text/plain we've been able to see that parts look something like [2]. Our suspect was that the multipart parser does not tolerate the quotes around UTF-8 but exploring the jungles of RFC they seem to be allowed as per an example of https://tools.ietf.org/html/rfc2045 that states: Note that the value of a quoted string parameter does not include the quotes. That is, the quotation marks in a quoted-string are not a part of the value of the parameter, but are merely used to delimit that parameter value. In addition, comments are allowed in accordance with RFC 822 rules for structured header fields. Thus the following two forms Content-type: text/plain; charset=us-ascii (Plain text) Content-type: text/plain; charset="us-ascii" are completely equivalent. Could we kindly have some feedback on this in order to avoid having to parse the whole multipart on our own? Thank you very much. Marco.
