Actually, XSLT support began in version 4.2. You can use xslt-eval() if you want to put the code inline in your XQuery. It requires some boilerplate, but the germane code (strip out <b> elements) is on one line:
declare variable $xslt := <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";> <!-- Strip out <b> elements --> <xsl:template match="b"/> <!-- But copy everything else unchanged --> <xsl:template match="@* | node()"> <xsl:copy> <xsl:apply-templates select="@* | node()"/> </xsl:copy> </xsl:template> </xsl:stylesheet>; for $doc in collection() return xdmp:xslt-eval($xslt,$doc) Evan Lenz Software Developer, Community MarkLogic Corporation http://community.marklogic.com On 6/14/12 11:21 AM, "David Lee" <[email protected]> wrote: >Unfortuantely that doesnt return the <doc> element ... >Its more tricky to exclude children but maintain the parent. >let $m := > <doc> > <a>a</a> > <b>b</b> > </doc> >return $m/node() except $m/b > >Simply returns > <a>a</a> > >First, if you know how to do this in XSLT then ML 5.0+ supports XSLT so >just use that. > >For pure XQuery its a bit more complex in the general case (arbitrary >deep elements).
