<p><code>SwiftSoup</code> is a pure Swift library, cross-platform (macOS, iOS, tvOS, watchOS and Linux!), for working with real-world HTML. It provides a very convenient API for extracting and manipulating data, using the best of DOM, CSS, and jQuery-like methods.
|
||
<code>SwiftSoup</code> implements the WHATWG HTML5 specification, and parses HTML to the same DOM as modern browsers do.</p>
|
||
<ul>
|
||
<li>Scrape and parse HTML from a URL, file, or string</li>
|
||
<li>Find and extract data, using DOM traversal or CSS selectors</li>
|
||
<li>Manipulate the HTML elements, attributes, and text</li>
|
||
<li>Clean user-submitted content against a safe white-list, to prevent XSS attacks</li>
|
||
<li>Output tidy HTML
|
||
<code>SwiftSoup</code> is designed to deal with all varieties of HTML found in the wild; from pristine and validating, to invalid tag-soup; <code>SwiftSoup</code> will create a sensible parse tree.</li>
|
||
</ul>

<p>The <code>parse(_ html: String, _ baseUri: String)</code> method parses the input HTML into a new <code>Document</code>. The base URI argument is used to resolve relative URLs into absolute URLs, and should be set to the URL where the document was fetched from. If that's not applicable, or if you know the HTML has a base element, you can use the <code>parse(_ html: String)</code> method.</p>
|
||
<p>As long as you pass in a non-null string, you're guaranteed to have a successful, sensible parse, with a Document containing (at least) a <code>head</code> and a <code>body</code> element.</p>
|
||
<p>Once you have a <code>Document</code>, you can get at the data using the appropriate methods in <code>Document</code> and its supers <code>Element</code> and <code>Node</code>.</p>

<p>The <code>parseBodyFragment</code> method creates an empty shell document, and inserts the parsed HTML into the <code>body</code> element. If you used the normal <code>SwiftSoup(_ html: String)</code> method, you would generally get the same result, but explicitly treating the input as a body fragment ensures that any bozo HTML provided by the user is parsed into the <code>body</code> element.</p>
|
||
<p>The <code>Document.body()</code> method retrieves the element children of the document's <code>body</code> element; it is equivalent to <code>doc.getElementsByTag("body")</code>.</p>

<p>A cross-site scripting attack against your site can really ruin your day, not to mention your users'. Many sites avoid XSS attacks by not allowing HTML in user submitted content: they enforce plain text only, or use an alternative markup syntax like wiki-text or Markdown. These are seldom optimal solutions for the user, as they lower expressiveness, and force the user to learn a new syntax.</p>
|
||
<p>A better solution may be to use a rich text WYSIWYG editor (like <a href="http://ckeditor.com" rel="nofollow">CKEditor</a> or <a href="https://www.tinymce.com" rel="nofollow">TinyMCE</a>). These output HTML, and allow the user to work visually. However, their validation is done on the client side: you need to apply a server-side validation to clean up the input and ensure the HTML is safe to place on your site. Otherwise, an attacker can avoid the client-side Javascript validation and inject unsafe HMTL directly into your site</p>
|
||
<p>The SwiftSoup whitelist sanitizer works by parsing the input HTML (in a safe, sand-boxed environment), and then iterating through the parse tree and only allowing known-safe tags and attributes (and values) through into the cleaned output.</p>
|
||
<p>It does not use regular expressions, which are inappropriate for this task.</p>
|
||
<p>SwiftSoup provides a range of <code>Whitelist</code> configurations to suit most requirements; they can be modified if necessary, but take care.</p>
|
||
<p>The cleaner is useful not only for avoiding XSS, but also in limiting the range of elements the user can provide: you may be OK with textual <code>a</code>, <code>strong</code> elements, but not structural <code>div</code> or <code>table</code> elements.</p>

<p>Use the attribute setter methods <code>Element.attr(_ key: String, _ value: String)</code>, and <code>Elements.attr(_ key: String, _ value: String)</code>.</p>
|

<p>If you need to modify the class attribute of an element, use the <code>Element.addClass(_ className: String)</code> and <code>Element.removeClass(_ className: String)</code> methods.</p>

<p>The <code>Elements</code> collection has bulk attribute and class methods. For example, to add a <code>rel="nofollow"</code> attribute to every <code>a</code> element inside a div:</p>

<p>The text setter methods mirror the [[HTML setter|Set the HTML of an element]] methods:</p>
|
||
<ul>
|
||
<li><code>Element.text(_ text: String)</code> clears any existing inner HTML in an element, and replaces it with the supplied text.</li>
|
||
<li><code>Element.prepend(_ first: String)</code> and <code>Element.append(_ last: String)</code> add text nodes to the start or end of an element's inner HTML, respectively
|

The text should be supplied unencoded: characters like <code><</code>, <code>></code> etc will be treated as literals, not HTML.</li>

<p>Elements provide a range of DOM-like methods to find elements, and extract and manipulate their data. The DOM getters are contextual: called on a parent Document they find matching elements under the document; called on a child element they find elements under that child. In this way you can window in on the data you want.</p>

<p>SwiftSoup elements support a <a href="https://www.w3.org/TR/2009/PR-css3-selectors-20091215/" rel="nofollow">CSS</a> (or <a href="http://jquery.com" rel="nofollow">jQuery</a>) like selector syntax to find matching elements, that allows very powerful and robust queries.</p>
|
||
<p>The <code>select</code> method is available in a <code>Document</code>, <code>Element</code>, or in <code>Elements</code>. It is contextual, so you can filter by selecting from a specific element, or by chaining select calls.</p>
|
||
<p>Select returns a list of <code>Elements</code> (as <code>Elements</code>), which provides a range of methods to extract and manipulate the results.</p>

<li><code>:has(seletor)</code>: find elements that contain elements matching the selector; e.g. <code>div:has(p)</code></li>
|
||
<li><code>:not(selector)</code>: find elements that do not match the selector; e.g. <code>div:not(.logo)</code></li>
|
||
<li><code>:contains(text)</code>: find elements that contain the given text. The search is case-insensitive; e.g. <code>p:contains(swiftsoup)</code></li>
|
||
<li><code>:containsOwn(text)</code>: find elements that directly contain the given text</li>
|
||
<li><code>:matches(regex)</code>: find elements whose text matches the specified regular expression; e.g. <code>div:matches((?i)login)</code></li>
|
||
<li><code>:matchesOwn(regex)</code>: find elements whose own text matches the specified regular expression</li>
|
||
<li>Note that the above indexed pseudo-selectors are 0-based, that is, the first element is at index 0, the second at 1, etc</li>
