Invalid character found: 'µ'.
by Erol Akarsu 09 Dec '11

09 Dec '11

When I was fetching and parsing some html documents with let $doc := http:send-request(<http:request method='get' href='{$url}'/>) I am getting an error: [FOHC0001] An HTTP error occurred: "1323441640568.xml" (Line 475): Invalid character found: 'µ'. It seems base is not able to handle special chracter 'µ'. Erol Akarsu

FW: database compatibility - adding several binary resource files
by Fabrice Etanchaud 09 Dec '11

09 Dec '11

Dear all at BaseX, 1. just in case... are databases created with BaseX 6.5 (and so backups) compatible with BaseX 7.0 ? 2. Is there a way to load several binary resource files with only one command or xquery function (like ADD or db:add for textual resources) ? Thank you for your fanstatic job. regards, Fabrice ETANCHAUD Senior Software Engineer edital Berkenlaan 1 B-1831 Brussels, Belgium <skype:fabrice.etanchaud?call> +32 2 716 32 32 general +32 2 716 32 20 fax fetanchaud(a)edital.com corsearch.com <http://www.corsearch.com/> | edital.com <http://www.edital.com/> Confidentiality Notice: This email and its attachments (if any) contain confidential information of the sender.

No results for query. Please help!
by Subhro Moitra 09 Dec '11

09 Dec '11

Hello, I am getting to know Basex702. I downloaded the war and its receiving requests at http://localhost:8080/BaseX702/rest (tomcat servlet container) I am using curl to query the REST urls for results. I used the command below to populate the initial data *$$ curl -i -X PUT -H "Content-Type: application/xml" -T "/tmp/bv_letsbuycom_standard_client_feed.xml" "admin:admin@localhost :8080/BaseX702/rest/bvstandard"* To confirm the PUT above i do this: *$$ curl -i "admin:admin@localhost:8080/BaseX702/rest/bvstandard"* .... ...... <rest:database name="bvstandard" resources="1" xmlns:rest=" http://www.basex.org/rest"> <rest:resource type="xml" content-type="application/xml" size="828733">bvstandard.xml</rest:resource> </rest:database> Another confirmation *$$ curl -i "admin:admin@localhost :8080/BaseX702/rest/bvstandard/bvstandard.xml"* * * The above shows the entire xml. So the data got loaded fine i believe. Now i am stuck. a query like below is not resulting any results. The xml document surely contains the path and data. *$$ curl -i "admin:admin@localhost :8080/BaseX702/rest/bvstandard?query=/Feed/Product&wrap=no"* There are multiple Product elements under the Feed element. And the above query returns empty results. I know i am doing something fundamentally wrong, but not sure what. However, a request like *$$ curl -i "admin:admin@localhost :8080/BaseX702/rest/bvstandard?query=//@id"* * * Shows results as expected, ie all the attributes *id * and its values are displayed. Please help. Aren't the values of query param in the GET url above, a XPATH expression? How to i execute a xpath on the DB to get the results, using the REST interface. The main purpose is to get some 100 MB large xml file into BaseX and then query it using a php client and display results on a web page. We at letsbuy.com is really interested in integrating BaseX in our application for handling all the XML feeds we consume. Please advice. Thanks, Subhro.

Dear all, I'm trying to download a jpg from the web and then write it in a file. Everything goes right, but at the end the file is not a valid image... it contains extra bytes... could you please tell me where I went wrong ? declare default element namespace "http://www.w3.org/1999/xhtml"; file:write-binary('c:/fe/img.jpg', http:send-request(<http:request method='get' override-media-type=image/jpeg'/>, http:send-request(<http:request method='get' />, 'http://www.patentsoffice.ie/eregister/register/TMRegister.aspx?idAppli= 2005/01446')[2]//img/@src[contains(.,'TM')]/data() ) ) With a typeswitch I can see that the response body is a xs:base64Binary, so it should fit correctly in the file:write-binary function... best regards Fabrice ETANCHAUD Senior Software Engineer edital Berkenlaan 1 B-1831 Brussels, Belgium <skype:fabrice.etanchaud?call> +32 2 716 32 32 general +32 2 716 32 20 fax fetanchaud(a)edital.com corsearch.com <http://www.corsearch.com/> | edital.com <http://www.edital.com/> Confidentiality Notice: This email and its attachments (if any) contain confidential information of the sender.

BaseX on Android
by Andy Bunce 08 Dec '11

08 Dec '11

Hi, I remember seeing some discussion of research into this a while back. I have just got a Android tablet so was wondering what the state of play is on this? I come across JBED http://forum.xda-developers.com/showthread.php?t=1189303which seems to claim the ability to run jars though an emulation layer. I tried this but it is looking for a midlet/jad descriptor file. I will investigate this, but has anybody been down this route? /Andy

how to get at the XML within the XML?

I triggered a bug. make basex -q 'declare option output:cdata-section-elements "desc M";document{(doc("AMFMXTaiwan.gpx")//*:wpt[1]/*:desc/data())}' Potential bug? Improper use?

You see I'm trying to figure how to get a inner shred of XML, <description><![CDATA[<ul><li>復興廣播電台...</li><li>台北市士...</li><li>丙</li></ul>]]></description> parsed just like the enclosing file. Maybe I need some "util:eval()". You see I want to access the inner elements with //li[2] etc. instead of matches(*:desc,concat('/li><li>(',$x,')')) like a dweeb. Help.

I have been using http module w/o any issue before. Today, I tried it with latest release 7.0.2 but getting error "Error parsing entity as XML or HTML." Did I miss anything to run? return http:send-request(<http:request method='get' href=' http://www.google.com'/>) Error: [FOHC0002] Error parsing entity as XML or HTML. Thanks Erol Akarsu

Fwd: Insert position of attributes
by Jan Vlčinský (CAD) 04 Dec '11

04 Dec '11

Hi Regarding the (not existent) requirement for attribute order: In http://www.w3.org/TR/2008/REC-xml-20081126/#sec-starttags there is a note "Note that the order of attribute specifications in a start-tag or empty-element tag is not significant." And my recommendation is: Do not put any extra requirements to any XML, which is not really needed. In case of attributes, you may and up promissing your consumers that the order of attributes will be as you define, and later you may have problems switching tools, which follow W3C recommendation, but not your extra promise. So the general advice is: keep your promises at minimum possible, it will easy work for you and also for your partners. The same often applies, when people start insisting on certain XML encoding, encoding or not encoding of special characters - all these requirements are more cosmetic then practical and often do originate from people, who do not understand the topic so well, but are well trained in the exercise "find three differences it those two pictures".

cdata-section-elements collisions
by jidanni＠jidanni.org 04 Dec '11

declare option output:cdata-section-elements "description"; works great, except that I want it to work only on my //Folder/description's not my //Placemark/description's. I read http://www.w3.org/TR/2010/REC-xslt-xquery-serialization-20101214/index.html… and http://docs.basex.org/wiki/Serialization and no matter what I do...
