SLAX-1.1 includes complete support for all XSLT elements.
The apply-imports statement applies any templates imported from other files.
Read more in the docs.
The attribute statement creates an attribute, giving the name and
value for the attribute. This is used when the attribute name is not
static.
<data> {
attribute $type _ $number {
expr value;
}
}
Read more in the docs.
The attribute-set statement defines a set of attributes.
Read more in the docs.
The copy-node statement copies a node, while allowing additional
content to be supplied.
copy-node . {
<new> "content";
}
Read more in the docs.
The decimal-format statement defines details about the formatting of
numbers.
Read more in the docs.
The element statement creates an element, giving a name and contents
for that element. This is used when the element name is not static.
element $type _ $number {
expr "content";
}
Read more in the docs.
The fallback statement is used when an extension element or function
is not available.

The preserve-space statement defines elements for which internal
whitespace is to be preserved.
Read more in the docs.
The sort statement defines the order in which the for-each or
apply-templates statements visit a set of nodes.
Read more in the docs.
The strip-space statement defines elements for which internal
whitespace is to be removed.

SLAX-1.1 introduces mutable variables, whose values can be changed. Mutable variables are not part of XSLT and their use can make your script unportable to other XSLT engines. See Mutable Variables for associated issues.
The append statement appends a value to a mutable variable.
append $mvar += <new> "content";
Read more in the docs.
The mvar statement declares a mutable variable.
mvar $mvar;
Read more in the docs.
The set statement sets the value of a mutable variable.
set $mvar = <my> "content";
Read more in the docs.
The while statement is a control statement that loops until the text
expression is false. Note that this is only possible if the test
expression contains a mutable variable.
while (count($mvar) < 10) {
/* do more work */
}

SLAX-1.1 defines a new set of statements, providing additional functionality for SLAX scripts.
The for statement is a control statement that iterates thru a set of
values, assigning each to a variable before evaluating a block of statements.
for $i ($min ... $max) {
<elt> $i;
}
Read more in the docs.
The function statement defines an extension function, usable in
XPath expressions.
function my:lesser ($a, $b) {
if ($a < $b) {
result $a;
} else {
result $b;
}
}
Functions use the EXSLT function package.
Read more in the docs.
The result statement defines the result value for a function.

The trace statement allows trace data to be written to the trace
file.
trace "my debug value is " _ $debug;
trace {
if ($debug/level > 4) {
<debug> {
copy-of $data;
}
}
}

The sequence operator ("...") creates a sequence of elements between two integer values. Two values are used, with the "..." operator between them. The values are both included in the range. If the first value is less than the second one, the values will be in increasing order; otherwise the order is decreasing.
for $tens (0 ... 9) {
message "... " _ tens _ "0 ...";
for $ones (0 ... 9) {
call test($value = $tens * 10 + $ones);
}
}

The node-set assignment operator (":=") assigns a node-set while avoiding the evils of RTFs. This allows the assigned value to be used directly without the need for the node-set() function.
var $data := {
<one> 1;
<two> 2;
<three> 3;
<four> 4;
}
var $name = $data/*[. == $count];

The ternary operator ("?:") makes a simple inline if/else test, in the pattern of C/Perl. Two formats are supported. The first format gives a condition, the value if the condition is true, and the value if the condition is false. The second format uses the first value if the condition is true and the second if it is false.
var $class = (count(items) < 10) ? "small" : "large"; var $title = data/title ?: "unknown";

SLAX supports the use of "#!/path/to/slaxproc" as the first line of a SLAX script. This allows scripts to be directly executable from the unix shell.
