No, it can be matched as often as you like. Suppose the source document has: > <book title="All About Foo" author="Dr. Quux"/> > and I want to place the title in one part of the result tree > and the author > in another. To do so, I might have > <xsl:apply-templates select="book[@title]"/> > in one place, and > <xsl:apply-templates select="book[@author]"/> > in the other.

Several points here: - if you want to have one template for each attribute, you can: <xsl:template match="book/@title"> <xsl:apply-templates select="book/@title"> <xsl:template match="book/@author"> <xsl:apply-templates select="book/@author"> - normally this isn't necessary. Instead of matching the attribute with a template, why not just access its value using <xsl:value-of select="book/@title"/> ? In addition, the > template > rule triggered by these two apply-templates tags cannot > distinguish which > apply-templates "call" triggered the rule, so it doesn't know which > attribute > to style (I'm guessing that this can be handled with a variable). You could distinguish the calls using a parameter, or using modes. But in this situation, you don't need to: think in terms of processing the attributes as nodes, not the elements they belong to. > > Am I missing or misunderstanding something? Yes!
