How to apply character style

[Rajendran_T]

Hi,

Can anyone helpme to develop a script to italic the contents inside the <em></em> tag in the InDesign document

Try this code:

applyCharacterStyle("em", "myCharacterStyle");
////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
function applyCharacterStyle(nodeName, characterStyle){
    var myDoc = app.documents[0];
    var xPath = ["//"+nodeName];
    var root = myDoc.xmlElements[0];
    var  node = null;
    try{
        var proc = app.xmlRuleProcessors.add(xPath);
        var match = proc.startProcessingRuleSet(root);
        while (match != undefined){
            node = match.element;
            match = proc.findNextMatch();
            if (node != null && node != undefined){
                node.texts[0].appliedCharacterStyle = characterStyle;
                }
            }
        }
    catch(ex){}
    finally{
        proc.endProcessingRuleSet();
        proc.remove();
        }
    }

Rajendran_T: 

I do that simply with a search and replace:

var tgRange = app.activeDocument.selection[0]; // If the target is a document, delete ".selection[0]"
var tgStyle = app.activeDocument.characterStyles.item("italic"); // Enter the actual character style name

app.findGrepPreferences = app.changeGrepPreferences = null;
app.findGrepPreferences.findWhat = "<em>.+?</em>";
app.changeGrepPreferences.appliedCharacterStyle = tgStyle;

tgRange.changeGrep();

// If you want to delete the tag itself, remove the following from the comment out.

// app.findGrepPreferences = app.changeGrepPreferences = null;
// app.findGrepPreferences.findWhat = "</?em>";
// app.findGrepPreferences.appliedCharacterStyle = tgStyle;
// app.changeGrepPreferences.changeTo = "";
// tgRange.changeGrep();

That means <em> is not a XML element, it is just content inside paragraph?

If it is just content only you can find & replace like that. 

But you asked that you need to apply style for a tag not a string....

Anyway good for you.

Thank you for pointing that out.
Apparently I made a mistake...
