read xml in reverse order

[Guest]

How to read xml elements in reverse order from the indesign structure panel??

I want to read the parent element of a particular element in a loop

Hi,

First of all, if you only need to retrieve string data from an element, I would definitively recomment using a XML object instead. It's much much faster.

var reverseXMLthroughObject = function() {
    var doc, xf, xo, cs, c, n, arr = [];

    if (!app.documents.length
    || !app.activeDocument.xmlElements[0].xmlElements.length) {
        alert("Nothing to work with…");
        return;
    }

    doc = app.activeDocument;
    xf = File ( Folder.temp+"/tmp.xml");
    doc.exportFile ( ExportFormat.XML, xf );
    xf.open('r');
    xo = XML(xf.read());
    xf.close();
    xf.remove();

    cs = xo.xpath("*/*");
    n = cs.length();

    while (n--) arr[arr.length]=String(cs);

    return arr.join(",");
}

reverseXMLthroughObject();

However if you need to do work with xmlElements inside the indesign structure, you may try this way.

var reverseXMLThroughStructure = function() {
    var doc, root, cs, c, n, arr = [];

    if (!app.documents.length
    || !app.activeDocument.xmlElements[0].xmlElements.length) {
        alert("Nothing to work with…");
        return;
    }

    doc = app.activeDocument;
    root = doc.xmlElements[0];
    cs = root.evaluateXPathExpression("./*");
    n = cs.length;

    while (n--) cs.texts[0].isValid && arr[arr.length]=cs.contents;

    return arr.join(",");
}

reverseXMLThroughStructure();

Another approach is XMLRules.
