kotlin生成带有ps前缀的xml

好的，以下是一个使用Kotlin生成带有前缀为ps的XML示例的代码：

import javax.xml.parsers.DocumentBuilderFactory
import javax.xml.transform.TransformerFactory
import javax.xml.transform.dom.DOMSource
import javax.xml.transform.stream.StreamResult

fun main() {
    val factory = DocumentBuilderFactory.newInstance()
    val builder = factory.newDocumentBuilder()
    val doc = builder.newDocument()

    val root = doc.createElementNS("http://www.example.com/ps", "ps:root")
    doc.appendChild(root)

    val person1 = doc.createElementNS("http://www.example.com/ps", "ps:person")
    root.appendChild(person1)

    val name1 = doc.createElementNS("http://www.example.com/ps", "ps:name")
    name1.appendChild(doc.createTextNode("John"))
    person1.appendChild(name1)

    val age1 = doc.createElementNS("http://www.example.com/ps", "ps:age")
    age1.appendChild(doc.createTextNode("30"))
    person1.appendChild(age1)

    val gender1 = doc.createElementNS("http://www.example.com/ps", "ps:gender")
    gender1.appendChild(doc.createTextNode("Male"))
    person1.appendChild(gender1)

    val person2 = doc.createElementNS("http://www.example.com/ps", "ps:person")
    root.appendChild(person2)

    val name2 = doc.createElementNS("http://www.example.com/ps", "ps:name")
    name2.appendChild(doc.createTextNode("Jane"))
    person2.appendChild(name2)

    val age2 = doc.createElementNS("http://www.example.com/ps", "ps:age")
    age2.appendChild(doc.createTextNode("25"))
    person2.appendChild(age2)

    val gender2 = doc.createElementNS("http://www.example.com/ps", "ps:gender")
    gender2.appendChild(doc.createTextNode("Female"))
    person2.appendChild(gender2)

    val transformerFactory = TransformerFactory.newInstance()
    val transformer = transformerFactory.newTransformer()
    transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2")
    transformer.setOutputProperty(javax.xml.transform.OutputKeys.INDENT, "yes")

    val source = DOMSource(doc)
    val result = StreamResult(System.out)
    transformer.transform(source, result)
}

这段代码会生成与之前示例相同的XML文档。希望这可以帮助到您！
