Script to automate the tagging of paragraph styles based on keyword

Hi,

 

I'm working on a load of files, aligning them to be accessible PDFs, and so trying to automate some of the small, repetitive tasks.

 

I'm after an InDesign script that can automate the tagging (for PDF) of paragraph styles (within 'Edit all export tags') based on a keyword (eg 'H1', 'H2' etc.) in the style name.

 

Can anyone shed any light on this, or is it even possible?

 

This is as far as I got, but it doesn't apply the tags:

 

var doc = app.activeDocument;
var styles = doc.paragraphStyles;

// Define keyword-to-tag mappings (uppercase)
var tagMappings = {
    "H1": "H1",
    "H2": "H2",
    "H3": "H3",
    "H4": "H4",
    "H5": "H5",
    "H6": "H6",
    "P": "P"
};

// Loop through all paragraph styles
for (var i = 0; i < styles.length; i++) {
    var style = styles[i];
    var styleName = style.name; // Keep original case (uppercase)

    // Check if the style name contains a keyword
    for (var key in tagMappings) {
        if (styleName.indexOf(key) !== -1) { // Match uppercase names

            var tagName = tagMappings[key];

            // Apply the export tag for PDF export
            try {
                style.exportTag = tagName;  // Set PDF export tag (corrected)
                $.writeln("Mapped: " + style.name + " → <" + tagName + "> for PDF export");
            } catch (e) {
                $.writeln("Error setting export tag for style " + style.name + ": " + e.message);
            }

            break; // Exit loop once a match is found
        }
    }
}

alert("Paragraph styles tagged with PDF export tags successfully!");

Hi @Phil5C41 you already have @Peter Kahrel's perfect answer so you're probably done, but I wanted to learn a bit about scripting style tag mapping myself, so I wrote a little script that does what your script is trying to do. I figured I may as well share it.

 

I changed your mapping system so that the tag names are the object keys and the values are RegExps. This is because I wanted to be able to have multiple paragraph styles that would be mapped to the same tag. For example, when headings appear in different colors to match a chapter color theme, we could name them "H1-Chapter 1", "H1-Chapter 2", etc, and the script would tag them all "H1". (This would have worked with your approach—using .indexOf—but it isn't as configurable as RegExp .test and it may give false positives, such as tagging a style named "MONTH1" as "H1".)

    Thank you, @Peter Kahrel and thanks also to you @m1b, this works well and yes, I had thought about the issue around style names eg 'MONTH1', but hadn't put a fix for that, so what you have supplied is great. Many thanks!!

      There's another problem. I'd forgotten how those tags should be scripted. You should use this format:

      app.documents[0].paragraphStyles.item('H1').styleExportTagMaps.add (
  'PDF', // exportType
  'H1', // exportTag
  '', // exportClass
  '' //exportAttributes
);

        If your styles are in style groups, then your script doesn't see them. Change this line:

        var styles = doc.paragraphStyles;

        to:

        var styles = doc.allParagraphStyles;

        and see if it makes a difference.

        Thanks, Peter, they are not in Style Groups, just separate styles.

         

        I get the same result, the script seems to run as I get the confirmation alert, but on looking at the Tags, they're all still set to '[Automatic]'.
