Interceptors

You can define interceptors chains that could transform HTML during building or make some observations. There is a default "filter interceptor", so you can filter out some elements.
Below is an example that filters HTML that way so all div will be omited but content will remain
println(document {
append.filter { if (it.tagName == "div") SKIP else PASS }.html {
body {
div {
a { +"link1" }
}
a { +"link2" }
}
}
}.serialize())The code above will produce the following output
<!DOCTYPE html>
<html>
<body>
<a>link1</a><a>link2</a>
</body>
</html>The other interceptor doesn't mutate HTML but measures generation time
System.out.appendHTML().measureTime().html {
head {
title("Welcome page")
}
body {
div {
+"<<<special chars & entities goes here>>>"
}
div {
CDATA("Here is my content")
}
}
}.let {
println()
println("Generated in ${it.time} ms")
}
