    copied!<p>I am writing an HTML parser, which uses TagSoup to pass a well-formed structure to XMLSlurper.</p> <p>Here's the generalised code:</p> <pre><code>def htmlText = """ &lt;html&gt; &lt;body&gt; &lt;div id="divId" class="divclass"&gt; &lt;h2&gt;Heading 2&lt;/h2&gt; &lt;ol&gt; &lt;li&gt;&lt;h3&gt;&lt;a class="box" href="#href1"&gt;href1 link text&lt;/a&gt; &lt;span&gt;extra stuff&lt;/span&gt;&lt;/h3&gt;&lt;address&gt;Here is the address&lt;span&gt;Telephone number: &lt;strong&gt;telephone&lt;/strong&gt;&lt;/span&gt;&lt;/address&gt;&lt;/li&gt; &lt;li&gt;&lt;h3&gt;&lt;a class="box" href="#href2"&gt;href2 link text&lt;/a&gt; &lt;span&gt;extra stuff&lt;/span&gt;&lt;/h3&gt;&lt;address&gt;Here is another address&lt;span&gt;Another telephone: &lt;strong&gt;0845 1111111&lt;/strong&gt;&lt;/span&gt;&lt;/address&gt;&lt;/li&gt; &lt;/ol&gt; &lt;/div&gt; &lt;/body&gt; &lt;/html&gt; """ def html = new XmlSlurper(new org.ccil.cowan.tagsoup.Parser()).parseText( htmlText ); html.'**'.grep { it.@class == 'divclass' }.ol.li.each { linkItem -&gt; def link = linkItem.h3.a.@href def address = linkItem.address.text() println "$link: $address\n" } </code></pre> <p>I would expect the each to let me select each 'li' in turn so I can retrieve the corresponding href and address details. Instead, I am getting this output:</p> <pre><code>#href1#href2: Here is the addressTelephone number: telephoneHere is another addressAnother telephone: 0845 1111111 </code></pre> <p>I've checked various example on the web and these either deal with XML, or are one-liner examples like "retrieve all links from this file". It's seems that the it.h3.a.@href expression is collecting all hrefs in the text, even though I'm passing it a reference to the parent 'li' node. </p> <p>Can you let me know:</p> <ul> <li>Why I'm getting the output shown </li> <li>How I can retrieve the href/address pairs for each 'li' item</li> </ul> <p>Thanks.</p>
