<preformat> Preformatted Text

Text in which spaces, tabs, and line feeds must be preserved. Content is typically displayed in monofont to preserve character alignment.

Usage/Remarks

The <preformat> element is typically used for machine-related communication such as man-machine dialogs and error message reports with descriptions, in which whitespace such as tabs, line feeds, and spaces should be preserved.
The MathML elements to describe equations are not permitted within <preformat>. If equations are encountered within computer code, they can be tagged using the element <named-content> to preserve the fact that they were equations or the element <styled-content> to preserve that fact that they were set in a math font.
Position
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 fragments are typically anchored whereas longer preformats such as ASCII art are typically placed elsewhere such as in a separate window or at the end of the document.
Related Elements
Best Practice: Although it is possible to use <preformat> to tag any format-preserving object, some of these objects have semantic elements that should be used in preference. For example:
  • Poetry and verse should usually be tagged with the <verse-group> element, which may not preserve the exact indentation, but is likely to be displayed in a proportional font.
  • Programming code, pseudo-code, DTDs and Schemas, and XML instances should be tagged with the <code> element, making full use of its attributes to identify the type of code.
  • Equations and math are typically tagged with <disp-formula> or <inline-formula>.

  <preformat>... who would fardels bear,
   To grunt and sweat under a weary life,
   But that the dread of something after death,
   The undiscover&rsquo;d country from whose bourn
   No traveller returns, puzzles the will
   And makes us rather bear those ills we have
