This is a scala wrapper over jsoup to access html content in a functional way.
Some examples:
- this is how to traverse html using
flatMap
import uk.gov.voa.htmlcheck.Html
import uk.gov.voa.htmlcheck.Html.Implicits._
import uk.gov.voa.htmlcheck.elements.ElementAttribute.IdAttribute
import uk.gov.voa.htmlcheck.elements.{Div, TextArea}
val html = Html(
"""<div id="div">
| <textarea id="1" class="area-class"></textArea>
| <p></p>
| <div id="inner-div">
| <textarea id="2" class="area-class"></textArea>
| </div>
|</div>
|""".stripMargin)
val textArea2 = html
.findOnlyDescendantBy[IdAttribute, Div]("div")
.flatMap(_.findFirstChildBy[IdAttribute, Div]("inner-div"))
.flatMap(_.onlyChild[TextArea])
val textArea2Id = textArea2.getOrError.id.asString- and using
for
import cats.data.Xor.Right
import uk.gov.voa.htmlcheck.Html
import uk.gov.voa.htmlcheck.Html.Implicits._
import uk.gov.voa.htmlcheck.elements.ElementAttribute.IdAttribute
import uk.gov.voa.htmlcheck.elements.{Div, TextArea}
val html = Html(
"""<div id="div">
| <textarea id="1" class="area-class"></textArea>
| <p></p>
| <div id="inner-div">
| <textarea id="2" class="area-class"></textArea>
| </div> approach
|</div>
|""".stripMargin)
val Right((textArea2, id)) = for {
div <- html.findOnlyDescendantBy[IdAttribute, Div]("div")
innerDiv <- div.findFirstChildBy[IdAttribute, Div]("inner-div")
textArea2 <- innerDiv.onlyChild[TextArea]
id <- textArea2.id
} yield textArea2 -> idThis code is open source software licensed under the Apache 2.0 License.
