[SOLVED] Kotlin Multiplatform/JS Unresolved reference Document.evaluate()

Kotlin Multiplatform/JS Unresolved reference Document.evaluate()

Context: Kotlin Multiplatform JavaScript.

I'm trying to use a Document.evaluate() but getting Unresolved reference: evaluate and Unresolved reference: XPathResult.

import org.w3c.dom.Document
import org.w3c.dom.parsing.DOMParser

object JavascriptTest {
    // language=HTML
    private val html = """
            <body>
               <div>
                  <a class="button" href="http://exaple.com">Example</a>
               </div>
            </body>
        """.trimIndent()

    fun parseXpath() {
        val parser = DOMParser()
        val document: Document = parser.parseFromString(html, "text/html")
        val xpath = "//div/a[contains(@class, \"button\")]"
        document.evaluate(xpath, document, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null)
    }
}

build.gradle.kts

kotlin {
    js(IR) {
        useCommonJs()
        browser {}
        binaries.executable()
    }

   sourceSets {
      val jsTest by getting
   }

Solution

As far as I know there is no bindings for XPathEvaluator interface out of the box right now. But you could add them by yourself using asDynamic:

val XPathResult = window.asDynamic().XPathResult

fun Document.evaluate(
    xpathExpression: String,
    contextNode: Node,
    namespaceResolver: Any?,
    resultType: Any,
    result: Any?
): dynamic =
    asDynamic().evaluate(xpathExpression, contextNode, namespaceResolver, resultType, result)
