You would need to wrap the string in a document:
<xsl:variable name="input-doc" as="document-node()">
<xsl:document>
<xsl:value-of select="unparsed-text('input.txt')"/>
</xsl:document>
</xsl:variable>
However this is pretty convoluted. If you define a function word-count($string)
then you can (a) use this in your accumulator, and (b) apply it to a string
directly, without any need for accumulators or document nodes.
Personally I wouldn't use accumulators for this unless (a) you intend to use
streaming, or (b) there is a need to get the wordcount for arbitrary parts of
the document, e.g. chapters or sections.

Hi all,
I'm exploring ways with XSLT 3.0's xsl:accumulator instruction in a non
streaming way, to count number of words within text documents (both XML and
.txt input files).
Below is what I've tried so far with input XML documents, using examples
borrowed from XSLT 3.0 spec.
XML input document:
<document>
Lorem Ipsum is simply dummy text of the printing and typesetting industry.
Lorem Ipsum
has been the industry's standard dummy text ever since the 1500s, when an
unknown
printer took a galley of type and scrambled it to make a type specimen
book. It has
survived not only five centuries, but also the leap into electronic
typesetting, remaining
essentially unchanged. It was popularised in the 1960s with the release of
Letraset sheets
containing Lorem Ipsum passages, and more recently with desktop publishing
software like
Aldus PageMaker including versions of Lorem Ipsum.
</document>
I wish to find, the word count within the XML element "document" above.
XSLT stylesheet:
<xsl:stylesheet version="3.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform
<http://www.w3.org/1999/XSL/Transform>"
xmlns:xs="http://www.w3.org/2001/XMLSchema <http://www.w3.org/2001/XMLSchema>"
exclude-result-prefixes="xs">
<xsl:output method="text"/>
<xsl:mode use-accumulators="w"/>
<xsl:accumulator name="w" initial-value="0" as="xs:integer">
<xsl:accumulator-rule match="text()"
select="$value + count(tokenize(.))"/>
</xsl:accumulator>
<xsl:template match="document">
<xsl:variable name="wordCount" select="accumulator-after('w') -
accumulator-before('w')"/>
<xsl:value-of select="$wordCount"/>
</xsl:template>
</xsl:stylesheet>
When the above XSLT stylesheet, is applied to the earlier mentioned XML input
document, the word count is correctly displayed as output of XSLT
transformation (answer is 91 with the above example).
If I've a text input document (say a file inp1.txt), as following (italics is
just to emphasize, what is within the .txt file),
Lorem Ipsum is simply dummy text of the printing and typesetting industry.
Lorem Ipsum
has been the industry's standard dummy text ever since the 1500s, when an

How would an XSLT 3.0 transform using xsl:accumulator, needs to be written,
to count number of words with the mentioned .txt file?
Thanks for any replies.
