A variation on this, which works equally well, is to delimit the text with empty
The effect of this is that the extra newlines and spaces now belong to whitespace-only nodes, which are stripped from the stylesheet and ignored.
Examples
Here are two simple examples using
1.
Output first-name and last-name, separated by a space:
Another way to achieve the same effect is to use the
concat()
function:
2.
Output a comma-separated list of values:
The purpose of the empty
elements is to split the comma and the following newline character into separate text nodes; this ensures that the newline character becomes part of a whitespace-only node and is therefore not copied to the output. The final
Another way to achieve this is with the separator attribute of

Why is it useful to have two names for the same thing? Probably because it's the easiest way for a standards committee to keep all its members happy. More seriously, the existence of these two names is indicative of the fact that some people see XSLT as being primarily a language for transforming trees, while others see its main role as defining presentation styles. Take your pick.

Changes in 2.0
In XSLT 2.0 the value to be output can be obtained by evaluating a contained sequence constructor as an alternative to using the
select
attribute.
A
separator
attribute has been added, allowing a sequence of values to be output separated by spaces, commas, or any other convenient string.
Format
select? = expression
separator? = { string}
disable-output-escaping? = “yes” | “no”>

Attributes
| Name | Value | Meaning |
| select optional | XPath Expression | The value to be output. |
| separator optional | Attribute value template returning a string | A string to be used to separate adjacent items in the output. |
| disable-output-escaping optional, deprecated |  yes orno | The valueyesindicates that special characters in the output (such as<) should be output as is, rather than using an XML escape form such as<. The default value isno. |
