EPScript
Data Types
Strings and characters
These are contained within either double quotes ("") or single quotes (''). There is no difference between the two, but it may be easier to use one sort when inside an XML attribute. For example:
<when test="type = 'patent'"> ... </when>
Numbers
Logical Operators
and
<if test="type = 'book' and is_set( creators )"> ... </if>
or
<if test="type = 'book' or type = 'patent'"> ... </if>
not
<if !is_set( creators )"> ... </if>
Comparison Operators
lt
<if test="length(editors) lt 6"> ... </if>
gt
<if test="length(editors) gt 1"> ... </if>
equals
<if test="type = 'patent'"> ... </if>
Control Structures
if
<if test="date_effective">(<print expr="date_effective" opts="res=year" />)</if>
choose/when/otherwise
<choose> <when test="title"><print expr="title" /></ep:when> <otherwise><print expr="type" /> #<print expr="eprintid" /></otherwise> </choose>
Procedures
<print expr="isbn" />
