Attributes

Attributes of elements follow the style of XML. The attribute name is followed by an equal sign (=) and the value of the attribute.



<element attr1="one" attr2="two">;

Where XSLT allows attribute value templates using curly braces, SLAX uses the normal expression syntax. Attribute values can include any XPath syntax, including quoted strings, parameters, variables, numbers, and the SLAX concatenation operator, which is an underscore (_).



<location state=$location/state zip=$location/zip5 _ "-" _ $location/zip4>;

The XSLT equivalent:



<location state="{$location/state}" 
                 zip="{concat($location/zip5, "-", $location/zip4}"/>

Curly braces placed inside quote strings are not interpreted as attribute value templates. Instead, they are interpreted as plain-text curly braces.

An escape sequence causes a character to be treated as plain text and not as a special operator. For example, in HTML, an ampersand (&) followed by lt causes the less-than symbol (<) to be printed.

In XSLT, the double curly braces ({{ and }}) are escape sequences that cause opening and closing curly braces to be treated as plain text. When a SLAX script is converted to XSLT, the curly braces inside quote strings are converted to double curly braces:



<avt sign="{here}">;

The XSLT equivalent:



<avt sign="{{here}}"/>
