scala 字符串到 scala.xml.Elem

Scala是一种功能强大的静态类型编程语言，它在处理字符串到scala.xml.Elem的转换时非常方便。本文将介绍如何将字符串转换为scala.xml.Elem，并提供相关的案例代码。

scala
import scala.xml.XML
val xmlString = "John Doe"
val xmlElem = XML.loadString(xmlString)

scala
import scala.xml.XML
val xmlString = "John Doe"
val xmlElem = XML.loadString(xmlString)
// 获取标题元素的文本内容
val title = (xmlElem \ "title").text
// 修改作者元素的文本内容
xmlElem match {
  case { titleElem }{ authorElem } =>
    xmlElem.copy(child = Seq(titleElem, Jane Doe))
}
// 添加新的子元素
val updatedXmlElem = xmlElem match {
  case { titleElem }{ authorElem } =>
    xmlElem.copy(child = Seq(titleElem, authorElem, 2021))
}
