Preformatted Text


Used for preformatted text, such as computer code, in which white space (such as tabs, line feeds, and spaces) should be preserved.

This element’s content typically is displayed or printed in a monofont to preserve character alignment.


Authoring and Conversion Note: The position attribute may be used to indicate whether this element must be anchored at its exact location within the text or whether it may float, for example, to the top of the next page, next column, to the end of a logical file, or within a separate window. For the typical <preformat> element, the “float or anchor” decision will be governed by the size of the object. For example, short code fragments are typically anchored whereas full programs are typically placed elsewhere, such as in a separate window or at the end of the article.

<p>Trees, of course, are hardly a random choice for our
methodology.... Hierarchical trees have been understood as a
way of viewing document structures since the earliest days of
SGML development. Our initial tree structure was very simple:
&lt;!ELEMENT  implications  (tree+) &gt;

&lt;!ELEMENT  root          (term, synonym?) &gt;
&lt;!ELEMENT  branches      (term | (term, synonym) | tree)* &gt;
Terms are the literal strings for which the Ferret engine searches; they
are the most specific expressions to be found in real documents of the
concepts on which classifications rules act.</p>...
