Try using <code>scala.xml.parsing.XhtmlParser</code> instead.

I have just tried to use this answer with scala 2.8.1 and ended up using the work from:

The interesting bit that I needed was:

<pre><code>val parserFactory = new org.ccil.cowan.tagsoup.jaxp.SAXFactoryImpl
val parser = parserFactory.newSAXParser()
val source = new org.xml.sax.InputSource("http://www.scala-lang.org")

<h1>Scala Scraper</h1>

I recommend <a href="https://github.com/ruippeixotog/scala-scraper" rel="nofollow noreferrer">Scala Scraper</a> that lets you parse HTML elegantly like this:

<pre><code>// Parse elements from files, URLs or plain strings
val browser = JsoupBrowser()
val doc = browser.parseFile("core/src/test/resources/example.html")
val doc2 = browser.get("http://example.com")
val doc3 = browser.parseString("&lt;html&gt;&lt;h1&gt;parse me&lt;/h1&gt;&lt;/html&gt;")

// Extract the text inside the element with id "header"
doc &gt;&gt; text("#header")

// Extract the &lt;span&gt; elements inside #menu
val items = doc &gt;&gt; elementList("#menu span")

// From each item, extract all the text inside their &lt;a&gt; elements
items.map(_ &gt;&gt; allText("a"))
</code></pre>

How do you load an HTML DOM document into Scala? The XML singleton had errors when trying to load the xmlns tags.

<pre><code>import java.net._
import java.io._
import scala.xml._

object NetParse {

 import java.net.{URLConnection, URL}
 import scala.xml._

 def netParse(sUrl: String): Elem = {
 var url = new URL(sUrl)
 var connect = url.openConnection

 XML.load(connect.getInputStream)
 }
}
</code></pre>

<hr>

Finally I found a solution! - Requires scala 2.7.7 or higher to work (2.7.0 has a fatal bug):

Scala and HTML parsing

如何将HTML DOM文档加载到Scala中？XML singleton在尝试加载xmlns标记时出错。import java.net._import java.io._import scala.xml._object NetParse {   import java.net.{URLConnection, URL}   import scala.xml._   def netParse(sUrl
