Conditional SimpleXML possible?

I am pulling content from an XML file with SimpleXML.

I was wondering if it is possible to display a certain node depending on the contents of the node, e.g.

<article>
    <title>PHP</title>
    <content>yada yada yada</content>
</article>

<article>
    <title>JAVASCRIPT</title>
    <content>yodo yodo yodo</content>
</article>

Can SimpleXML find a specific title and then display the article for that title?

Display article whose title is 'PHP'.

I really hope this is possible.

Thanks to anyone who replies.

See PHP DevCenter, here is a sample: 

$article_list = new SimpleXMLElement($article_xml);  
foreach ($article_list->xpath("//article[title='PHP']/content") as $content) { 
    print "$content\n";
}

Also if you know the exact location of the article nodes it is better to avoid the // notation which will search in all levels of the XML.

You could use an XPath expression like //article[title='PHP']/content

$article_list = new SimpleXMLElement($article_xml);
foreach($article_list->article as $i => $article) {
    if('PHP' == $article->title) {
        //code to display article.
    }
}

This is assuming the article tags are in a parent element.
