[BUG] Different errors using collection() in xslt.

Open inmorteveritas opened this issue 2 years ago • 1 comments

Describe the bug

Try to use collection() in XSLT. Different attempts produce different errors. See examples. It is definitely related to #351.

  • with xmldb:exist:// it throws java.io.IOException: Resource /db/test is a collection. . A xmlParser error.
  • without xmldb:exist://it throw XSL transform reports fatal error: Relative URI passed to document() function (/db/test); but no base URI is available. resolve-uri('','/db/test') doesn't help.
  • Calling collection(<catalogfile.xml>) doesn't work like suggested in https://www.saxonica.com/documentation10/#!sourcedocs/collections.

Further investigation reveals that the problem existed like "forever": https://markmail.org/message/l6rfv6hw5ojxbt7v#query:+page:1+mid:l6rfv6hw5ojxbt7v+state:results

Expected behavior

Expect access to the XML tree created by collection(). Either as in exist-db or as in Saxon, for example, via a catalogue structure.

To Reproduce

Example 1 - absolute URI with xmldb:exist/

let $dummyColl      := xmldb:create-collection('/db','test'),
    $store-dummy    := xmldb:store($dummyColl, 'test.xml', <test/>),
    $stylesheet     := 
                        <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"version="2.0">
                            <xsl:variable name="coll" select="collection('xmldb:exist:///db/test')"/>
                        <xsl:template match="/">
                            <result>
                                <xsl:value-of select="node-name($coll/*)"/>
                            </result>
                        </xsl:template>
                        </xsl:stylesheet>
return 
    transform:transform(doc($store-dummy), $stylesheet, ())

Example 2 - without xmldb:exist://

<xsl:variable name="coll" select="collection('/db/test')"/>

Errors

Possible Workaround

As I understand it, Saxon's XSL handling of the function collection('xmldb:exist:///db/test/catalog.xml') is that it calls the individual file paths in the catalogue to the files and calls a doc() in a function for each. The workaround "reproduces" this by calling uri-collection('xmldb:exist:///db/test/catalog.xml') and iterating over the generated sequence and calling doc(). Not really elegant and fast, because it is not possible to filter beforehand (e.g. with xPath conditions), but has to open each file to examine it.

Therefore, it may be necessary to store content retrieved from collections in temporary helper files. Since the parameterisation of nodes is also not possible. (see https://stackoverflow.com/questions/40694551/passing-a-node-as-parameter-to-a-xsl-stylesheet)

xquery version "3.1";

declare function local:make-catalog($col-path as xs:string*) as item() {
    <collection stable="true" xml:base="xmldb:exist://">
        {
            for $doc in collection($col-path)/*
            return
                <doc href="{document-uri(root($doc))}"/>
        }
    </collection>
};

let $dummyColl      := xmldb:create-collection('/db','test'),
    $store-dummy    := xmldb:store($dummyColl, 'test.xml', <test/>),
    $catalog        := xmldb:store("/db/test","catalog.xml",local:make-catalog('/db/test')),
    $stylesheet     := 
                        <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"version="2.0">
                        <xsl:variable name="coll" select="uri-collection('xmldb:exist:///db/test/catalog.xml')"/>
                        <xsl:template match="/">
                            <result>
                                <xsl:value-of select="for $d in $coll return node-name(doc($d)/*)"/>
                                <!-- OR -->
                                <xsl:for-each select="$coll">
                                    <xsl:value-of select="node-name(doc(.)/*)"/>
                                </xsl:for-each>
                            </result>
                        </xsl:template>
                        </xsl:stylesheet>
return 
    transform:transform(doc($store-dummy), $stylesheet, ())
