    copied!<p>I'm trying to parse out values from a Widget <a href="http://dev.w3.org/2006/waf/widgets/#configuration-document" rel="nofollow noreferrer">config.xml</a> using shell. I do want to use sed for this task. If there is something that <a href="http://suckless.org/" rel="nofollow noreferrer">sucks less</a> than xsltproc, I'd love to know. </p> <p>In this example I am after the <strong>id</strong> attribute value from the <code>config.xml</code> below:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;widget xmlns="http://www.w3.org/ns/widgets" id="http://example.org/exampleWidget" version="2.0 Beta" height="200" width="200"&gt; &lt;name short="123"&gt;Foo Widget&lt;/name&gt; &lt;/widget&gt; </code></pre> <p>I wish it was as simple as <a href="http://docs.jquery.com/Attributes/attr" rel="nofollow noreferrer">Jquery's attr</a>: <code>var id = $("widget").attr("id");</code></p> <p>Currently this shell code utilising <code>xsltproc</code> fails:</p> <pre><code>snag () { TMP=$(tempfile) cat &lt;&lt; EOF &gt; $TMP &lt;xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"&gt; &lt;xsl:output method="text" encoding="utf-8" indent="no"/&gt; &lt;xsl:template&gt; &lt;xsl:value-of select="$1"/&gt; &lt;/xsl:template&gt; &lt;/xsl:stylesheet&gt; EOF echo $(xsltproc $TMP config.xml) rm -f $TMP } ID=$(snag "widget/@id") if test "$ID" = "http://example.org/exampleWidget" then echo Mission accomplished. else echo "&lt;$ID&gt; is wrong." fi </code></pre>
