Format text to bold

Question

I have one xml file and I am reading data from it using indesign java scripting. At one point I got stuck whenever I get text in xml enclosed within '<b>'INDIA'</b>' then should get converted to bold INDIA font for after executing java script. Is there any way in indesign java script to convert that specific text into bold or other font style.

I don't have coded anything but below is the code which I found on Web but also not working

var doc = app.activeDocument;

var frame = doc.pages[0].textFrames.add({
geometricBounds: [700, 50, 500, 200]
});

var bold = doc.characterStyles.add({name:"Bold", fontStyle:"Bold"});
var none = doc.characterStyles.itemByName("[None]");

frame.insertionPoints.lastItem().applyCharacterStyle(none);

frame.insertionPoints.lastItem().contents = "I really like";

frame.insertionPoints.lastItem().applyCharacterStyle(bold);

frame.insertionPoints.lastItem().contents = " walking to the park";

frame.insertionPoints.lastItem().applyCharacterStyle(none);

frame.insertionPoints.lastItem().contents = " and eating icecream";

Answer 1

Your sample only needed a little modification to be effective. The default character and paragraph styles always have the index set to 0 as they can't be nor moved nor removed.

So you may try this :

var doc = app.activeDocument;

var frame = doc.pages[0].textFrames.add({ geometricBounds: [700, 50, 500, 200] });

var bold = doc.characterStyles.itemByName ("Bold"); !bold.isValid && bold = doc.characterStyles.add({name:"Bold", fontStyle:"Bold"});

var none = doc.characterStyles[0]; //similmar to "[None]"

frame.insertionPoints.lastItem().applyCharacterStyle(none);

frame.insertionPoints.lastItem().contents = "I really like";

frame.insertionPoints.lastItem().applyCharacterStyle(bold);

frame.insertionPoints.lastItem().contents = " walking to the park";

frame.insertionPoints.lastItem().applyCharacterStyle(none);

frame.insertionPoints.lastItem().contents = " and eating icecream";

Here you are
