Working with page code
XHTML requirement
Actions Dreamweaver performs
All elements in the document must nest properly:
Generates correctly nested code and, when cleaning up XHTML,
corrects nesting in code that was not generated by Dreamweaver.
<p>This
is a <i>bad example.</p></i> <p>This is
a <i>good example.</i></p>
All element and attribute names must be lowercase.
Forces HTML element and attribute names to be lowercase in the
XHTML code that it generates and when cleaning up XHTML,
regardless of your tag and attribute case preferences.
Every element must have a closing tag, unless it is declared in the DTD Inserts closing tags in the code that it generates, and when cleaning
as EMPTY.
up XHTML.
Empty elements must have a closing tag, or the opening tag must end Inserts empty elements with a space before the closing slash in empty
tags in the code that it generates, and when cleaning up XHTML.
with />. For example, <br> is not valid; the correct form is
<br></br> or <br/>. Following are the empty elements: area,
base, basefont, br, col, frame, hr, img, input, isindex, link,
meta, and param.
And for backwards-compatibility with browsers that are not XMLenabled, there must be a space before the /> (for example, <br />,
not <br/>).
Attributes can’t be minimized; for example, <td nowrap> is not
valid; the correct form is <td nowrap="nowrap">.
Inserts full attribute-value pairs in the code that it generates, and
when cleaning up XHTML.
This affects the following attributes: checked, compact, declare,
defer, disabled, ismap, multiple, noresize, noshade,
nowrap, readonly, and selected.
Note: If an HTML browser does not support HTML 4, it might fail to
interpret these Boolean attributes when they appear in their full form.
All attribute values must be surrounded by quotation marks.
Places quotation marks around attribute values in the code that it
generates, and when cleaning up XHTML.
The following elements must have an id attribute as well as a name Sets the name and id attributes to the same value, whenever the
name attribute is set by a Property inspector, in the code that
attribute: a, applet, form, frame, iframe, img, and map. For
example, <a name="intro">Introduction</a> is not valid; the Dreamweaver generates, and when cleaning up XHTML.
correct form is
<a id="intro">Introduction</a> or <a id="section1"
name="intro"> Introduction</a>.
For attributes with values of an enumerated type, the values must be Forces enumerated type values to be lowercase in the code that it

lowercase.
An enumerated type value is a value from a specified list of allowed
values; for example, the align attribute has the following allowed
values: center, justify, left, and right.
All script and style elements must have a type attribute.
(The type attribute of the script element has been required since
HTML 4, when the language attribute was deprecated.)
All img and area elements must have an alt attribute.
Sets the type and language attributes in script elements, and the
type attribute in style elements, in the code that it generates and
when cleaning up XHTML.
Sets these attributes in the code that it generates and, when cleaning
up XHTML, reports missing alt attributes.
Regular expressions
Regular expressions are patterns that describe character combinations in text. Use them in your code searches to help
describe concepts such as lines that begin with “var” and attribute values that contain a number.
