  1. POConfiguring an XML Namespace
    text
    copied!<p>I have made an XML generator with a few different options, one is a style option which defines whether to use attributes or elements for primitive data types. </p> <p>XML schemas aren't supported right now, but I need to allow the setup of an XML Namespace, and I have been doing some research. My understanding is the XML namespace can have a prefix, but it doesn't have to. It also needs a unique string attribute value that is <strong>usually</strong> a URI, but doesn't have to be.</p> <p>I am a little bit confused, as I am new to XML namespaces, and I have a few questions about this, if we take a look at an example xml document</p> <pre><code>&lt;?xml version="1.0"?&gt; &lt;root xmlns="some_identifier"&gt; &lt;oneKey&gt;value&lt;/oneKey&gt; &lt;/root&gt; </code></pre> <p>This is using an element style of the key value example, and I'm going to allow the configuration of "some_identifier". In this example is the "oneKey" element under the XML namespace? Or do I have to specify a prefix like <code>xmlns:ns</code> and then prefix "oneKey" with "ns"? </p> <p>Also if we take a look at attribute style:</p> <pre><code>&lt;?xml version="1.0"?&gt; &lt;root xmlns="some_identifier" oneKey="value" /&gt; </code></pre> <p>Do we need to define a similar prefix in oneKey in this example?</p> <p>I apologize if I'm way off the mark in these questions, please let me know if I'm just not making sense,</p> <p>UPDATE:</p> <p>I have found this site: <a href="http://www.rpbourret.com/xml/NamespacesFAQ.htm#exec_1" rel="nofollow">http://www.rpbourret.com/xml/NamespacesFAQ.htm#exec_1</a></p> <p>That says these two are identical:</p> <pre><code>&lt;foo:A xmlns:foo="http://www.foo.org/"&gt; &lt;foo:B&gt;abcd&lt;/foo:B&gt; &lt;/foo:A&gt; </code></pre> <p>and</p> <pre><code>&lt;A xmlns="http://www.foo.org/"&gt; &lt;B&gt;abcd&lt;/B&gt; &lt;/A&gt; </code></pre> <p>which is very useful, but regarding the attribute style. Do I need to prefix attributes? Or will the xmlns default work for these as well?</p>
