<h1 class="topictitle1">Editing in the Source view</h1>
<div><p>You can use the Source view to view and work with a file's source
code directly.</p>
<div class="section"><p> The Source view has many text editing features, such as:</p>
<dt class="dlterm">Syntax highlighting</dt>
<dd>Each tag type is highlighted differently, enabling you to easily find
a certain kind of tag for editing. In addition, syntax highlighting is valuable
in locating syntax errors. For example, if you begin a comment in the middle
of the document with <samp class="codeph">&lt;!--</samp> everything until the next <samp class="codeph">--&gt;</samp> is
considered a comment, and will be highlighted accordingly. The large highlighted
area will indicate that you need to add <samp class="codeph">--&gt;</samp> to close the
comment.<p>You can customize the syntax highlighting. Refer to the related
tasks for more information.</p>
<dt class="dlterm">Unlimited undo and redo</dt>
<dd>These options allow you to incrementally undo and redo every change made
to a file for the entire editing session. For text, changes are incremented
one character or set of selected characters at a time.</dd>
<dt class="dlterm">Content assist</dt>
<dd>Content assist helps you finish tags and insert macros. Refer to the related
task for more details.</dd>
<dt class="dlterm">Template</dt>
<dd>You can access templates (using content assist) to help you quickly add
regularly-used tagging combinations. Refer to the related task for more details.</dd>
<dt class="dlterm">Node selection</dt>
<dd>Based on the location of your cursor (or selection in the Outline view),
the node selection indicator highlights the line numbers that include a node
(for example, an element or attribute), in the vertical ruler in the left
area of the Source view.</dd>
<dt class="dlterm">Pop-up menu options</dt>
<dd>From the editor's pop-up menu, you have many of the same editing options
available as you do from the workbench <strong>Edit</strong> menu. You can select menu
options such as: <span class="uicontrol">Cleanup Document,</span> to open the <span class="uicontrol">Cleanup</span>
dialog, which contains settings to update a document so that it is well-formed
and formatted and <span class="uicontrol">Format,</span> which formats either the
entire document or selected elements.</dd>
<dt class="dlterm">"Smart" double clicking</dt>
<dd>You can use double-click to select attribute values, attribute-value pairs,
and entire tag sets to quickly update, copy, or remove content.</dd>
<p>To open an XML file to edit, right-click the file in the
Navigator view and select <span class="uicontrol">Open With &gt; XML Editor</span>. Click
the <span class="uicontrol">Source</span> to see the Source view.</p>
<p>Edit the code
as necessary, using any of the available features. As you move the cursor
within your XML file (or select items from the Outline view), the node selection
indicator will highlight the line numbers that encompass the node (for example,
an element or attribute). You can use smart double-clicking behavior to select
attribute values, attribute-value pairs, and entire tag sets to quickly update,
copy, or remove content. If desired, validate and save the XML

Design view and the Outline view.</p>
