Introduction to XSL Functions (1)

This issue introduces multiple XSL methods and attributes for VBScript, JScript, to give full play to the XML advantages for < Xsl:script >, < xsl:eval > Markup Expression Authoring or < Xsl:if >, < xsl:when > Expr attribute.

First, Absolutechildnumber

Meaning: Returns the ordinal number of a node relative to all its siblings (regardless of the name)

Syntax: Absolutechildnumber (node)

Parameters: node── object, to return the number of nodes.

Example:

1. Assume that the document structure is:< documents >< head/>< body/></document, where documentation is the top-level node and the following expression outputs

< Xsl:eval >

Absolutechildnumber (This.selectnodes ("/document/body"). Item (0))

</xsl:eval >

2. Determine the serial number of the current node relative to all of its brothers

< Xsl:eval >absolutechildnumber (this) </xsl:eval >

Second, Ancestorchildnumber

Meaning: Returns the ordinal number of the nearest ancestor node (relative to the same node) based on the given ancestor node name, starting at the given node. Returns 0 if the ancestor is not found.

Syntax: Ancestorchildnumber (Bstrnodename, Pnode)

Parameters:

bstrnodename── string. The name of the ancestor node being searched.

pnode── object. The node where the search starts.

Example:

Finds the nearest name of the current node, called the statement ancestor node.

Ancestorchildnumber ("The", this)

Third, attributes

Meaning: Returns a collection of node attributes

Syntax: object.attributes

Parameters: object── Node Object

Example:

Number of current node properties

This.attributes.length

The value of the third property of the current node

This.attributs.item (2). value

or This.attributes.item (2). Text

or This.attributes (2). Text

Note: If the given subscript is larger than the property sum minus 1, the subscript for the first property is 0.

Four, BaseName

Meaning: Returns the base name with a namespace limit, that is, not including the name prefix

Syntax: Object.basename

Parameters: object── Node Object

Example: the base name of the current node: this.basename

Five, Childnumber

Meaning: Returns the ordinal number of a node relative to a sibling of the same name

Syntax: Childnumber (object)

Parameter: object─? Cape Leng Yun?/p>

Example: Assuming that the XML document is structured as follows

< x >< y >< z >< z/>< y/></x >

If the current node is Z, Childnumber (this) returns 1, and Absolutechildnumber (this) returns 3.
