Chapter 1: First Steps with XSLT

Key Points

❑ A stylesheet processor uses built-in rules for processing by default.

❑ You override these rules by using speciﬁc template rules to match elements

in an XML source document with XPath expressions.

❑ You can specify different output methods in a stylesheet — XML, XHTML,

HTML and text — and deﬁne the preferred character encoding too.

❑ Literal result elements and attributes are often used to deﬁne output struc-

tures.

❑ Output element content is usually speciﬁed by selecting values in the source

with XPath expressions.

❑ Always check for default namespace declarations in source ﬁles and set the

xpath-default-namespace

attribute on the

<xsl:stylesheet>

element to

this value.
