Display a reading duration

Post by **gbv34** » Mon Jun 27, 2022 9:08 pm

Hello!
I'm looking a way to display the reading duration for a topic.
Currently, my best lead is an XSLT shared in this forum that displays the number of words contained in a map.

Code: Select all

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <xsl:output indent="yes"/>

    <xsl:template match="/">

        <counts>

            <xsl:apply-templates/>

        </counts>

    </xsl:template>

    <xsl:template match="text()"/>

    <xsl:template match="*[contains(@class, 'map/map')]">

        <xsl:variable name="text">

            <xsl:apply-templates mode="getText" select="node()"/>

        </xsl:variable>

        <count>

            <xsl:value-of
                select="count(tokenize(lower-case($text), '(\s|[,.!:;]|[n][b][s][p][;])+')[string(.)])"/>

        </count>

        <xsl:apply-templates/>

    </xsl:template>

    <xsl:template match="*[contains(@class, 'map/map')]" mode="getText"/>

</xsl:stylesheet>

However, what I don't get is how I could insert the results in the first topic of the map, as a kind of infoblock.
Also, having the number of words is a good basis, but it should be necessary to proceed some calculation. I found this nice little js function which provides a rough estimation based on a word per minute.

Code: Select all

function readingTime() {
  const text = document.getElementById("article").innerText;
  const wpm = 225;
  const words = text.trim().split(/\s+/).length;
  const time = Math.ceil(words / wpm);
  document.getElementById("time").innerText = time;
}
readingTime();

Is there any way to apply such a function with xslt?
Has someone in the forum already met this need?

Any feedback is welcome. I recognize I was surprise nit seeing any plugin developed for that.

Hi gbv34,

Do you want this for PDF or HTML5 output, or both? This might influence how the implementation would work.

Hi Chris,
I intend to achieve this feature for HTML files.

Hi gbv34,

How would you want it annotated to the HTML output? Is there a specific HTML structure you would want?

Maybe just as a proof of concept, I could put the information in an HTML <abstract> element?

Hi again

Actually, I don't have a specific requirement for that but I thought it would be more relevant to place it close to the main heading in a topic, right after the opening of the <body> element.
