+<p><code>htmltidy</code> &mdash; Tidy Up and Test XPath Queries on HTML and XML Content</p>
+<p>Partly inspired by <a href="http://stackoverflow.com/questions/37061873/identify-a-weblink-in-bold-in-r">this SO question</a> and because there&rsquo;s a great deal of cruddy HTML out there that needs fixing to use properly when scraping data.</p>
+<p>It relies on a locally included version of <a href="http://www.html-tidy.org/"><code>libtidy</code></a> and works on macOS, Linux &amp; Windows.</p>
+<p>It also incorporates an <code>htmlwidget</code> to view and test XPath queries on HTML/XML content.</p>
+<p>The following functions are implemented:</p>
+<ul>
+<li>
+<code>tidy_html</code>: Tidy or &ldquo;Pretty Print&rdquo; HTML/XHTML Documents</li>
+<li>
+<code>html_view</code>: HTML/XML pretty printer and viewer</li>
+<li>
+<code>xml_view</code>: HTML/XML pretty printer and viewer</li>
+<li>
+<code>html_tree_view</code>: HTML/XML tree viewer</li>
+<li>
+<code>xml_tree_view</code>: HTML/XML tree viewer</li>
+</ul>

+<p>Let&rsquo;s see what <code><a href="reference/tidy_html.response.html">tidy_html()</a></code> does to it.</p>
+<p>It can handle the <code>response</code> object directly:</p>
+<div class="sourceCode"><pre class="sourceCode r"><code class="sourceCode r"><span class="kw">cat</span>(<span class="kw"><a href="reference/tidy_html.response.html">tidy_html</a></span>(res, <span class="kw">list</span>(<span class="dt">TidyDocType=</span><span class="st">"html5"</span>, <span class="dt">TidyWrapLen=</span><span class="dv">200</span>)))
+## &lt;!DOCTYPE html&gt;
+## &lt;html&gt;
+## &lt;head&gt;
+## &lt;meta name="generator" content="HTML Tidy for HTML5 for R version 5.0.0"&gt;
+## &lt;style&gt;
+## body { font-family: sans-serif; }
+## &lt;/style&gt;
+## &lt;title&gt;&lt;/title&gt;
+## &lt;/head&gt;
+## &lt;body&gt;
+## &lt;b&gt;This is some &lt;i&gt;really&lt;/i&gt; poorly formatted HTML as is this &lt;span id="sp"&gt;portion&lt;/span&gt;&lt;/b&gt;
+## &lt;div&gt;&lt;span id="sp"&gt;&lt;/span&gt;&lt;/div&gt;
+## &lt;/body&gt;
+## &lt;/html&gt;</code></pre></div>
+<p>But, you&rsquo;ll probably mostly use it on HTML you&rsquo;ve identified as gnarly and already have that HTML text content handy:</p>
+<div class="sourceCode"><pre class="sourceCode r"><code class="sourceCode r"><span class="kw">cat</span>(<span class="kw"><a href="reference/tidy_html.response.html">tidy_html</a></span>(<span class="kw">content</span>(res, <span class="dt">as=</span><span class="st">"text"</span>), <span class="kw">list</span>(<span class="dt">TidyDocType=</span><span class="st">"html5"</span>, <span class="dt">TidyWrapLen=</span><span class="dv">200</span>)))
+## &lt;!DOCTYPE html&gt;
+## &lt;html&gt;
+## &lt;head&gt;
+## &lt;meta name="generator" content="HTML Tidy for HTML5 for R version 5.0.0"&gt;
+## &lt;style&gt;
+## body { font-family: sans-serif; }
+## &lt;/style&gt;

+## &lt;/head&gt;
+## &lt;body&gt;
+## &lt;b&gt;This is some &lt;i&gt;really&lt;/i&gt; poorly formatted HTML as is this &lt;span id="sp"&gt;portion&lt;/span&gt;&lt;/b&gt;
+## &lt;div&gt;&lt;span id="sp"&gt;&lt;/span&gt;&lt;/div&gt;
+## &lt;/body&gt;
+## &lt;/html&gt;</code></pre></div>
+<p>NOTE: you could also just have done:</p>
+<div class="sourceCode"><pre class="sourceCode r"><code class="sourceCode r"><span class="kw">cat</span>(<span class="kw"><a href="reference/tidy_html.response.html">tidy_html</a></span>(<span class="kw">url</span>(<span class="st">"http://rud.is/test/untidy.html"</span>), 
+              <span class="kw">list</span>(<span class="dt">TidyDocType=</span><span class="st">"html5"</span>, <span class="dt">TidyWrapLen=</span><span class="dv">200</span>)))
+## &lt;!DOCTYPE html&gt;
+## &lt;html&gt;

+## &lt;/head&gt;
+## &lt;body&gt;
+## &lt;b&gt;This is some &lt;i&gt;really&lt;/i&gt; poorly formatted HTMLas is this &lt;span id="sp"&gt;portion&lt;/span&gt;&lt;/b&gt;
+## &lt;div&gt;&lt;span id="sp"&gt;&lt;/span&gt;&lt;/div&gt;
+## &lt;/body&gt;
+## &lt;/html&gt;</code></pre></div>
+<p>You&rsquo;ll see that this differs substantially from the mangling <code>libxml2</code> does (via <code>read_html()</code>):</p>
+<div class="sourceCode"><pre class="sourceCode r"><code class="sourceCode r">pg &lt;-<span class="st"> </span><span class="kw">read_html</span>(<span class="st">"http://rud.is/test/untidy.html"</span>)

+<p>But, you&rsquo;re probably better off running it on plain HTML source.</p>
+<p>Since it&rsquo;s C/C++-backed, it&rsquo;s pretty fast:</p>
+<div class="sourceCode"><pre class="sourceCode r"><code class="sourceCode r">book &lt;-<span class="st"> </span><span class="kw">readLines</span>(<span class="st">"http://singlepageappbook.com/single-page.html"</span>)
+<span class="kw">sum</span>(<span class="kw">map_int</span>(book, nchar))
+## [1] 207501
+<span class="kw">system.time</span>(tidy_book &lt;-<span class="st"> </span><span class="kw"><a href="reference/tidy_html.response.html">tidy_html</a></span>(book))
+##    user  system elapsed 
+##   0.021   0.001   0.022</code></pre></div>
+<p>(It&rsquo;s usually between 20 &amp; 25 milliseconds to process those 202 kilobytes of HTML.) Not too shabby.</p>

+    
+    <p>HTML documents can be beautiful and pristine. They can also be
+wretched, evil, malformed demon-spawn. Now, you can tidy up that HTML and XHTML
+before processing it with your favorite angle-bracket crunching tools, going beyond
+the limited tidying that &#39;libxml2&#39; affords in the &#39;XML&#39; and &#39;xml2&#39; packages and
+taming even the ugliest HTML code generated by the likes of Google Docs and Microsoft
+Word. It&#39;s also possible to use the functions provided to format or &quot;pretty print&quot;
+HTML content as it is being tidied. Utilities are also included that make it
+possible to view formatted and &quot;pretty printed&quot; HTML/XML
+content from HTML/XML document objects, nodes, node sets and plain character HTML/XML
+using &#39;vkbeautify&#39; (by Vadim Kiryukhin) and &#39;highlight.js&#39; (by Ivan Sagalaev).
+Also (optionally) enables filtering of nodes via XPath or viewing an XML document
+in &quot;tree&quot; view using &#39;xml-viewer&#39; (by Julian Gruber). See
+<a href = 'https://github.com/vkiryukhin/vkBeautify'>https://github.com/vkiryukhin/vkBeautify</a> and
+<a href = 'https://github.com/juliangruber/xml-viewer'>https://github.com/juliangruber/xml-viewer</a> for more information about &#39;vkbeautify&#39;
+and &#39;xml-viewer&#39;, respectively.</p>

+      <p>File <a href = 'an issue'>https://github.com/hrbrmstr/htmltidy/issues</a> if there are other <code>libtidy</code>
+options you&#39;d like supported.</p>
+      <p>It is likely that the most used options will be:</p>
+      <p><ul>
+<li><code>TidyXhtmlOut</code> (logical),
+  </li>
+<li><code>TidyHtmlOut</code> (logical) and
+  </li>
+<li><code>TidyDocType</code> which should be one of &quot;<code>omit</code>&quot;,
+    &quot;<code>html5</code>&quot;, &quot;<code>auto</code>&quot;, &quot;<code>strict</code>&quot; or &quot;<code>loose</code>&quot;.
+</li>
+</ul></p>
+      <p>You can clean up Microsoft Word (2000) and Google Docs HTML via logical settings for
+<code>TidyWord2000</code> and <code>TidyGDocClean</code>, respectively.</p>
+      <p>It may also be advantageous to remove all comments with <code>TidyHideComments</code>.</p>
