A Scala XML EntityRef example (unicode character)

This page shows a good Scala XML EntityRef example:

import scala.xml._
val xml = <body>Hello{EntityRef("#8198")}World</body>

That page states that 8198 is the unicode value for a tiny space character.

That code isn't too helpful unless you can see it in the REPL, so here it is:

A Scala XML XPath example

I'm not going to take any time to describe the following Scala XML/XPath example, other than to say that when it's run, it produces the following output, which is a simulated receipt for an order at a pizza store:

How to load an XML URL in Scala (contents of an XML web page)

Scala XML FAQ: How do I load an XML URL in Scala? (How do I read/download the contents of an XML URL in Scala?)

To load the contents of an XML URL (web page) in Scala, such as an RSS news feed or RESTful web service, just use the load method of the Scala XML class:

Scala XML examples: XML literals, mixing XML and Scala source code, XPath searching

A really terrific feature about Scala is that XML handling is built into the language. This means you don't have to deal with XML as String objects, you deal with it as XML objects.

Here are just a few examples of using XML in Scala. First, you can create an XML literal like this:

scala> val hello = <p>Hello, world</p>
hello: scala.xml.Elem = <p>Hello, world</p>

Again, note that this is not a String, there are no double quotes; we've just defined an XML literal in Scala.

Scala cookbook recipes

Wow, I began by writing a few Scala programming tutorials just because I like the language, and as I look here a couple of months later I now have more than sixty tutorials. As a result, I thought I'd start organizing them here in the form a Scala Programming Cookbook.

Here's my current collection of Scala FAQs and recipes, in a "cookbook" format.

Scala XML - Searching XMLNS namespaces, XPath, and more

In my earlier tutorial on creating a Scala REST client using the Apache HttpClient library, I demonstrated how to download the contents of a Yahoo Weather API URL, and then parse those contents using the Scala XML library. I didn't discuss the XML searching/parsing process used in that source code, so in this article I'll take a few moments to look at that code.
