Loading and saving text-data of a “plugined” textarea in eXist-db with HTML forms

阅读更多关于 Loading and saving text-data of a “plugined” textarea in eXist-db with HTML forms

问题 My original need was that of getting a plugin (tailwriter) to work with XForms (within eXist-db + XSLTForms), in order to transform textareas into markdown editors. It turned out, however, to be a hard issue to be solved, in reason of the "difficult relations" between the CSSs and JSs used by the plugin and by XSLTForms (overlapping and conflicts). In other words, I couldn't succeed in applying the plugin to any xf:textarea. Therefore I opted for using a simple HTML form. This way I was able

How to pass an HTML widget's value from an HTML form to an Xquery in eXist-db?

阅读更多关于 How to pass an HTML widget's value from an HTML form to an Xquery in eXist-db?

问题 In my intention this question represents an universalization of a specific issue indicated in a previous request: see related question (this is why I dare to send a second help request). I still cannot find an answer to the problem of how exacltly an html widget's value could be passed to an Xquery. The specific widget is a textarea, added to an html form (not to an XForm!) by means of the external function, the code of which can be found within the mentioned related question. So, the

eXist-db passing parameters to templates through controller.xql (URL mapping)

阅读更多关于 eXist-db passing parameters to templates through controller.xql (URL mapping)

问题 I am working with eXist-db 4.2.1 and Xquery 3.1 using the eXist's default installation of controller.xql and view.xq . I have a document.html to which I pass any incoming url structured with /doc/some-requested-doc-id at the end to produce a dynamically-created page based on some-requested-doc-id . So, the incoming url can be either http://localhost:8080/exist/apps/deheresi/doc/MS609-0001 or http://localhost:8080/exist/apps/deheresi/doc/MS609-0001.xml and they are treated the same... In the

eXist-db / XSLT / Saxon collection() slow as molasses (or errors out with memory limit)

阅读更多关于 eXist-db / XSLT / Saxon collection() slow as molasses (or errors out with memory limit)

问题 Coming from this question, I managed one entirely unsatisfactory solution for accessing an eXist-DB collection() from an XSLT 2.0 document loaded from within an eXist-db/Xquery transformation function: The XSLT file declares a variable : <xsl:variable name="coll" select="collection('xmldb:exist:///db/apps/deheresi/data/collection_ms609.xml')"/> This points to a catalog xml file I created (per Saxon documentation) that looks like this, in order to load the actual collection: <collection stable

eXist-db - basic Lucene query returns empty sequence

阅读更多关于 eXist-db - basic Lucene query returns empty sequence

问题 In eXist-db 4.4 I am attempting to implement a basic Lucene query structure, but it is returning no results. In /db/apps/deheresi/data I have a collection of tei-xml documents which have the same structure, and I want to apply my query only to the text content found within the element tei:seg and its descendants. A typical sample would be: <TEI> <text> [...] <seg type="dep_event" subtype="event" xml:id="MS609-0001-1"> <pb n="1r"/> <lb break="n" n="1"/> <date type="deposition_date" when="1245
