<div class="block">
<span>建立HTML的文档。</span>
<span>此模式的目的是支持浏览和编辑。</span>
<span>因此，由HTML文档描述的结构默认情况下不会完全复制。</span>
<span>由默认建模的元素结构由<code>HTMLDocument.HTMLReader</code>类<code>HTMLDocument.HTMLReader</code> ， <code>HTMLEditorKit.ParserCallback</code>实现了解析器期望的<code>HTMLEditorKit.ParserCallback</code>协议。</span>
<span>要更改结构，可以继承<code>HTMLReader</code> ，并重新实现方法<a href="../../../../javax/swing/text/html/HTMLDocument.html#getReader-int-"><code>getReader(int)</code></a>以返回新的读者实现。</span>
<span>对于文档<code>HTMLReader</code>应征询创建的默认结构的细节。</span>
<span>意图是文档是无损的（虽然重现HTML格式可能会导致不同的格式）。</span>
<p> <span>该文档仅建立HTML，并且不会尝试在其中存储视图属性。</span> <span>元素由<code>StyleContext.NameAttribute</code>标识，该属性应始终具有标识元素种类的类型<code>HTML.Tag</code> 。</span> <span>一些元素（如注释）被合成。</span> <span><code>HTMLFactory</code>使用此属性来确定要构建什么样的视图。</span> </p>
<p> <span>本文档支持增量加载。</span> <span><code>TokenThreshold</code>属性控制在尝试更新文档的元素结构之前缓冲了多少解析。</span> <span>此属性由<code>EditorKit</code>设置，以便子类可以禁用它。</span> </p>
<p> <span><code>Base</code>属性确定相对URL被解析的URL。</span> <span>默认情况下，如果属性的值为URL， <code>Document.StreamDescriptionProperty</code> 。</span> <span>如果遇到&lt;BASE&gt;标签，基地将成为该标签指定的URL。</span> <span>因为基本URL是一个属性，它当然可以直接设置。</span> </p>
<p> <span>此文档的默认内容存储机制是间隙缓冲区（ <code>GapContent</code> ）。</span> <span>可以通过使用执行Content的构造函数来提供<code>Content</code>方法。</span> </p>
<h2> <span>修改HTMLDocument</span> </h2>
<p> <span>除了Document和StyledDocument提供的用于突变HTMLDocument的方法之外，HTMLDocument还提供了一些方便的方法。</span> <span>可以使用以下方法将HTML内容插入到现有文档中。</span> </p>
<ul>
<li> <span><a href="../../../../javax/swing/text/html/HTMLDocument.html#setInnerHTML-javax.swing.text.Element-java.lang.String-"><code>setInnerHTML(Element, String)</code></a></span> </li>
<li> <span><a href="../../../../javax/swing/text/html/HTMLDocument.html#setOuterHTML-javax.swing.text.Element-java.lang.String-"><code>setOuterHTML(Element, String)</code></a></span> </li>
<li> <span><a href="../../../../javax/swing/text/html/HTMLDocument.html#insertBeforeStart-javax.swing.text.Element-java.lang.String-"><code>insertBeforeStart(Element, String)</code></a></span> </li>
<li> <span><a href="../../../../javax/swing/text/html/HTMLDocument.html#insertAfterStart-javax.swing.text.Element-java.lang.String-"><code>insertAfterStart(Element, String)</code></a></span> </li>
<li> <span><a href="../../../../javax/swing/text/html/HTMLDocument.html#insertBeforeEnd-javax.swing.text.Element-java.lang.String-"><code>insertBeforeEnd(Element, String)</code></a></span> </li>
<li> <span><a href="../../../../javax/swing/text/html/HTMLDocument.html#insertAfterEnd-javax.swing.text.Element-java.lang.String-"><code>insertAfterEnd(Element, String)</code></a></span> </li>
</ul>
<p> <span>以下示例说明使用这些方法。</span> <span>每个示例假定HTML文档以以下方式初始化：</span> </p>
<pre> <span>JEditorPane p = new JEditorPane();
p.setContentType("text/html");
p.setText("..."); // Document text is provided below.
HTMLDocument d = (HTMLDocument) p.getDocument();</span> </pre>
<p> <span>使用以下HTML内容：</span> </p>
<pre> <span>&lt;html&gt;
&lt;head&gt;
&lt;title&gt;An example HTMLDocument&lt;/title&gt;
&lt;style type="text/css"&gt;
div { background-color: silver; }
ul { color: red; }
&lt;/style&gt;
&lt;/head&gt;
&lt;body&gt;
&lt;div id="BOX"&gt;
&lt;p&gt;Paragraph 1&lt;/p&gt;
&lt;p&gt;Paragraph 2&lt;/p&gt;
&lt;/div&gt;
&lt;/body&gt;
&lt;/html&gt;</span> </pre>
<p> <span>所有修改HTML文档的方法都需要一个<a href="../../../../javax/swing/text/Element.html" title="javax.swing.text中的接口"><code>Element</code></a> 。</span> <span>可以使用方法<a href="../../../../javax/swing/text/html/HTMLDocument.html#getElement-javax.swing.text.Element-java.lang.Object-java.lang.Object-"><code>getElement(Element e, Object attribute, Object value)</code></a>从HTML文档中获取元素。</span> <span>它以深度优先顺序返回包含具有给定值的指定属性的第一个后代元素。</span> <span>例如， <code>d.getElement(d.getDefaultRootElement(), StyleConstants.NameAttribute, HTML.Tag.P)</code>返回第一个段落元素。</span> </p>
<p> <span>定位元素的方便快捷方式是方法<a href="../../../../javax/swing/text/html/HTMLDocument.html#getElement-java.lang.String-"><code>getElement(String)</code></a> ;</span> <span>返回一个其<code>ID</code>属性与指定值匹配的元素。</span> <span>例如， <code>d.getElement("BOX")</code>返回<code>DIV</code>元素。</span> </p>
<p> <span><a href="../../../../javax/swing/text/html/HTMLDocument.html#getIterator-javax.swing.text.html.HTML.Tag-"><code>getIterator(HTML.Tag t)</code></a>方法也可用于查找文档中指定的HTML标签的所有出现。</span> </p>
<h3> <span>插入元素</span> </h3>
<p> <span>可以使用方法<code>insertAfterStart</code>和<code>insertBeforeEnd</code>将元素插入任何非叶元素的现有子元素之前或之后。</span> <span>例如，如果<code>e</code>是<code>DIV</code>元素， <code>d.insertAfterStart(e, "&lt;ul&gt;&lt;li&gt;List Item&lt;/li&gt;&lt;/ul&gt;")</code>插入<code>d.insertAfterStart(e, "&lt;ul&gt;&lt;li&gt;List Item&lt;/li&gt;&lt;/ul&gt;")</code>之前的列表，并且<code>d.insertBeforeEnd(e, "&lt;ul&gt;&lt;li&gt;List Item&lt;/li&gt;&lt;/ul&gt;")</code>在最后一段之后插入列表。</span> <span><code>DIV</code>块成为新插入元素的父代。</span> </p>
<p> <span>通过使用方法<code>insertBeforeStart</code>和<code>insertAfterEnd</code>可以在任何元素之前或之后插入<code>insertBeforeStart</code> <code>insertAfterEnd</code> 。</span> <span>例如，如果<code>e</code>是<code>DIV</code>元素， <code>d.insertBeforeStart(e, "&lt;ul&gt;&lt;li&gt;List Item&lt;/li&gt;&lt;/ul&gt;")</code>插入列表之前的<code>DIV</code>元素，而<code>d.insertAfterEnd(e, "&lt;ul&gt;&lt;li&gt;List Item&lt;/li&gt;&lt;/ul&gt;")</code>插入列表后的<code>DIV</code>元素。</span> <span>新插入的元素成为<code>DIV</code>元素的兄弟。</span> </p>
<h3> <span>更换元素</span> </h3>
<p> <span>可以使用方法<code>setInnerHTML</code>和<code>setOuterHTML</code>来代替<code>setInnerHTML</code>及其<code>setOuterHTML</code> 。</span> <span>例如，如果<code>e</code>是<code>DIV</code>元素， <code>d.setInnerHTML(e, "&lt;ul&gt;&lt;li&gt;List Item&lt;/li&gt;&lt;/ul&gt;")</code>用列表替换所有的孩子段落，并且<code>d.setOuterHTML(e, "&lt;ul&gt;&lt;li&gt;List Item&lt;/li&gt;&lt;/ul&gt;")</code>替换<code>DIV</code>元素本身。</span> <span>在后一种情况下，列表的父项是<code>BODY</code>元素。</span> </p>
<h3> <span>概要</span> </h3>
<p> <span>下表显示了上述各种方法的示例文档和结果。</span> </p>
