getURL

open fun getURL(attributes: Attributes, attribute: String): URL

Extract timestamp from attribute

Note that there are three “URL” classes and you need to choose wisely:

java.net.URL: Java 1.0 class to handle URLs. Tries to resolve the URL on the net. Will hang and throw exception when this fails. Try to avoid if at all possible.
java.net.URI: Java 1.4 replacement for java.net.URL. Use when you need a instance which is java.io.Serializable.
android.net.Uri: Android replacement for java.net.URL. Use when you need a instance which is android.os.Parcelable.
