You can use the / step operator to separate element names when you want to refer to a child of a particular node. For example, say that you want to create a rule that applies to only those < NAME > elements that are children of <PLANET> elements. In that case, you can match the expression "PLANET/NAME" . Heres a rule that surrounds the text of such elements in a <H3> HTML element:
<xsl:template match="PLANET/NAME"> <H3> <xsl:value-of select="."/> </H3> </xsl:template>
You also can use the * character as a wildcard, standing for any element. (* can match only elements, although note that the pattern @* can match any attribute.) For example, the following rule applies to all <NAME> elements that are grandchildren of <PLANET> elements:
<xsl:template match="PLANET/*/NAME"> <H3> <xsl:value-of select="."/> </H3> </xsl:template>
