This document introduces simple CNXML tags that are easy to use in Edit-in-Place.
This module also contains information derived from The Advanced CNXML by Ricardo Radaelli-Sanchez .

Starting with cnxml

To create the bare bones of content in Connexions, the author interface provides a variety of creation tools: the Document Importer, Edit-In-Place, and even a full-source editor. However, a basic knowledge of our markup language can help make small edits into tremendous enhancements to your material!

Connexions uses the Connexions Markup Language ( CNXML ) as its primary language for marking up and storing documents. CNXML is lightweight XML for marking up educational content. Unlike the well-known HTML, the goal of CNXML is to conveythe content of the material and not a particular presentation. For example, say you have the following sentence: I like cupcakes very much. However, you feel that you enthusiasm for cupcakes has not been fully expressed. In HTML, you would use bold, underline, italic, etc.; in CNXML, you would use the emphasis tag .

Inline tags

Inline tags, such as emphasis, are used to embed content and functionality inside the structural tags, such as paragraphs. Some of the more commonly used tags are discussed below.

Emphasis

As mentioned previously , the emphasis tag is used to accent certain text. Note that this refers to semantic emphasis and not a typeface. Different stylesheets can render emphasis with different typefaces.

<para id='intro'>Gardenias are my absolute<emphasis>favorite</emphasis>flower. Their petals are soft, and their bloom has anabsolutely<emphasis>heavenly</emphasis>scent.</para>

The above markup will display as:

Gardenias are my absolute favorite flower. Their petals are soft, and their bloom has an absolutely heavenly scent.

Term

The term tag is used to mark words or phrases which are being defined. However, itsuse is confined to either a para or definition tag. The term tag has one optional attribute : URL - a URL specifying the source or definition of theterm.

<para id='gardenia'><term url="http://en.wikipedia.org/wiki/Gardenia">Gardenias</term>can be tricky to maintain. The soil around the roots of a<term>gardenia</term>must remain moist always, but too much water can damage the plant. Also,<term>gardenias</term>enjoy the sun, but if the<emphasis>foliage</emphasis>gets wet to bring the gardenia into the shade.</para>

The above markup will display as:

Gardenias can be tricky to maintain. The soil around the roots of a gardenia must remain moist always, but too much water can damage the plant. Also, gardenias enjoy the sun, but if the foliage gets wet to bring the gardenia into the shade.

Note

The note tag creates an "out of line" note to the reader. The type of note is specified by an optional type attribute. If a type is not specified, the default is Note . The type attribute can contain any of the following values:

  • note
  • aside
  • warning
  • tip
  • important

<para id='pollen'>Receiving flowers is, on the whole, a wonderful thing. However, sometimes pollen from the flowers can causeproblems. In particular, the clean up of a bit of pollen can be tricky.<note type="Important">Do not use water when cleaning up pollen! This can lead tocounter-top and clothing stains!</note>Your best bet is to use a dry method of cleaning with a paper-towel.</para>

The above markup will display as:

Receiving flowers is, on the whole, a wonderful thing. However, sometimes pollen from the flowers can cause problems. In particular, the clean up of a bit of pollen can be tricky.

Do not use water when cleaning up pollen! This can lead to counter-top and clothing stains!
Your best bet is to use a dry method of cleaning, with a paper-towel, for example.
