So I'm converting a bunch of OOXML into DITA using XSLT 3 in oXygen with Saxon 9.8.0.12 PE. There's a requirement to use short (4 digit) unique identifiers for the resuling files and for these to be unique across the content set. There are many resulting DITA files per source OOXML document. "A chance to try accumulators!" I thought; I can pre-process the whole thing with file numbers in attributes. This isn't an attempt to use streaming; I've got a few tens of MB of source. The accumulator works, BUT the number sequence restarts if I try to use the accumuator across a sequence of document nodes or a sequence of element nodes. To produce a single continuous sequence of monotonically increasing integers with the accumulator, I have to get the whole content set into the same tree before creating the numbering attributes. Is that the expected behaviour? What I have defines the accumulator, <xsl:accumulator as="xs:integer" initial-value="0" name="documentNumber"> <xsl:accumulator-rule match="w:p[w:pPr/w:pStyle/@w:val = $listOfFileStyles]" select="$value + 1"> </xsl:accumulator-rule> </xsl:accumulator> pulls the content set into a variable using the file and arch extensions: <xsl:variable as="element(w:document)+" name="contentSet"> <xsl:for-each select="$OOXMLsrc"> <!-- a sequence of path strings --> <xsl:sequence select="(file:path-to-uri(.) => file:read-binary() => arch:extract-text('word/document.xml') => parse-xml())/*" /> </xsl:for-each> </xsl:variable> then applies the numbering template <xsl:variable as="element(w:document)+" name="numberedSrc"> <xsl:apply-templates mode="fileNumber" select="$contentSet" /> </xsl:variable> <xsl:mode name="fileNumber" on-no-match="shallow-copy" /> <xsl:template match="w:p[w:pPr/w:pStyle/@w:val = $listOfFileStyles]" mode="fileNumber" > <xsl:copy> <xsl:apply-templates mode="fileNumber" select="@*" /> <xsl:attribute name="fileNumber" select="accumulator-before('documentNumber') => format-number('0000')" /> <xsl:apply-templates mode="fileNumber" select="node()" /> </xsl:copy> </xsl:template> It works; the correct paragraphs are numbered. But the sequence restarts for each new member of the sequence. If instead I use: <xsl:variable as="element(bucket)+" name="contentSet"> <bucket> <xsl:for-each select="$OOXMLsrc"> <!-- a sequence of path strings --> <xsl:sequence select="(file:path-to-uri(.) => file:read-binary() => arch:extract-text('word/document.xml') => parse-xml())/*" /> </xsl:for-each> </bucket> </xsl:variable> <xsl:variable as="element(bucket)" name="numberedSrc"> <xsl:apply-templates mode="fileNumber" select="$contentSet" /> </xsl:variable> I get one continous sequence of numbers. Is there a better way to get the single continuous sequence of numbers? Thanks! -- Graydon
