Look at all Android layout files and collate what value is set for 'android:textColor' and count the usages of each

textcolor-stats.kts

val textColorsUsed = mutableMapOf<String, Int>()

File("../").walkTopDown().forEach { file ->
    if (file.isFile && file.extension == "xml" && file.path.contains("res/layout")) {
        val builder: DocumentBuilder = DocumentBuilderFactory.newInstance().newDocumentBuilder()
        val xmlInput = InputSource(StringReader(file.readText()))
        val doc: Document = builder.parse(xmlInput)

        val androidViews = XPathFactory.newInstance()
                .newXPath()
                .evaluate("//*", doc, XPathConstants.NODESET) as NodeList

        androidViews.forEach {
            it.attributes.getNamedItem("android:textColor")?.let { node ->
                textColorsUsed[node.nodeValue] = textColorsUsed.defaultOrIncrement(node.nodeValue)
            }
        }
    }
}
