Understanding Input Ports
Stylus Studio interprets input ports differently for different XSLT instructions, as shown in Table 66:

XSLT Instruction
|
Meaning of Input Port
|
|---|
xsl:value-of
|
Used to define the value of the select attribute. For example:
<xsl:value-of select="'Owen'">
|
xsl:for-each
|
Used to define the XPath expression for the select attribute. For example:
<xsl:for-each select="books/book">
|
xsl:if
|
Used to define the value of the test attribute. For example:
<xsl:if test="authors/author= 'Henry'">
See xsl:if and xsl:choose to learn more about when to use this instruction.
|
xsl:choose
|
Used to define the value of the test attribute of the nested xsl:when element. For example:
<xsl:when test="contains(authors/author,'Marchese')">
See xsl:if and xsl:choose to learn more about when to use this instruction.
|
xsl:apply-templates
|
Used to define the value of the select attribute. For example:
<xsl:apply-templates select="subject"/>
|
xsl:call-template
|
Used to define the value of the name attribute. For example:
<xsl:call-template name="newAuthorsTemplate"/>
|
Specifying Values for Input Ports
You can specify values for input ports by:
l Dragging a link from a source document node or from the output port of another block (like that of an XPath function or If block, for example).
l Double-clicking the port and typing a value (a string or an XPath expression, for example) in the Value dialog box.
Tip
|
|
When you mouse over an input port, Stylus Studio displays the value associated with that port.
|
Red Input Ports
If an xsl: instruction's attribute takes a literal or string value (such as xsl:value-of select="'Recommended'"/, for example) and a value has been provided for the attribute, Stylus Studio fills the input port associated with that attribute with a deep red to indicate that a value has been specified.
