Explanation of XSL series functions

The function | is reproduced in: China XML Forum

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.

VI. DataType

Meaning: Sets or reads the data type of a node

Syntax: Setting the data type of a node object.datatype=objvalue

Read the data type of the node objvalue=object.datatype

Parameters: object── Node Object

Example: Reading the data type of the current node

Dttype=this.datatype

Seven, depth

Meaning: Specifies the depth at which the node appears on the document tree, where the node is at the top level of the document, and the top-level node is located in the

The first layer, the root node (that is, the node represented by "/") is located on the No. 0 floor.

Syntax: Depth (pnode)

Parameters: pnode── Node Object

Example: The depth of the current node

Depth (this)

Viii. FirstChild, LastChild

Meaning: Returns the first child node (or last child node) of a node.

Syntax: Pnode.firstchild

Pnode.lastchild

Parameters: pnode── Node Object

Example: The name of the first node in the current node

This.firstChild.nodeName

Nine, Formatindex

Meaning: The supplied integer is formatted with the specified count system.

Syntax: Formatindex (lindex, Bstrformat)

Parameters:

lindex── integer value or variable

bstrformat── data format, optional values are a, a, I, I, 1, 01 (in 0-based numerical form, if required fixed-length numbers such as 0001, 0002 is very useful)

Example: uppercase Roman numeral number for the current node

Formatindex (Childnumber (this), "I")

Ten, FormatNumber

Meaning: Outputs a value in the specified format.

Syntax: FormatNumber (Dblnumber, Bstrformat)

Parameters: Description Same as FormatNumber, except that the format can be decimal

Example: The value of variable A is formatted as two decimal formatnumber (A, "#.00")

Xi. HasChildNodes

Meaning: Returns True (-1) If the node has a child node, or False (0)

Syntax: Pnode.haschildnodes ()

Note: Unlike the function described earlier, this function must be preceded by an empty bracket

Example: determining whether the current node has child nodes

This.haschildnodes

12, NamespaceURI, prefix

Meaning: Returns the global resource identifier (or prefix) of the node namespace

Syntax: Pnode.namespaceuri

Pnode.prifix

13, NextSibling, PreviousSibling, parentnode

Meaning: Returns the next sibling of the node (or the parent node of the previous sibling, or node)

Syntax: pnode.nextsibling

Pnode.previoussibling

Pnode.parentnode

Note: Applying the ParentNode method to the root node (that is, "/"), applying the PreviousSibling method to the first child node, and applying the NextSibling method to the last child node will result in an error that can be passed through the relational operator = = (equals) and the!= (Not equal) to determine whether a node is a specified node, in the form of pNode1 = PNode2 or PNode2!= pNode2.

14, NodeName

Meaning: Returns a specific string of elements, attributes, entry names, or other types of nodes

Syntax: Pnode.nodename

Example: The name of the current node

This.nodename

XV, NodeType, nodetypestring

Meaning: Returns the numeric form (or string form) of the type of the knot.

Syntax: Pnode.nodetype or pnode.nodetypestring

return value:

Node type
Node type number node type string

Elements
1
"Element"

Element attributes
2
"Attribute"

markup-delimited Region of Text
3
"Text"

Processing instruction
7
"Processing_instruction"

Comment
8
"Comment"

Document Entity
9
"Document"

16, nodetypedvalue

Meaning: Returns the value of a node as a node-predefined data type

Syntax: pnode.nodetypedvalue

Example: Assuming the data type of the current node is fixed.14.4, the following example returns the value of the node as a number, rather than a literal string

this.nodetypedValue

17, nodevalue

Meaning: Returns the text of a node

Syntax: Pnode.nodevalue

Note: This method is not used for element class nodes and can be used for attributes, CDATA, annotations, text, and so on.

Example: The value of the first property of the current element

This.attributes (0). Nodevalue

The text within the current element (assuming that there is only text in the element, no other elements, that is, < Mark >text</mark), and it is recommended that you try to master its exact usage several times.

This.firstChild.nodeValue

18, Ownerdocument

Meaning: Returns the root of the document that contains the node

Syntax: pnode.ownerdocument

Note: This method is used for document root node errors

19, SelectNodes

Meaning: The given style match applies to the current node and returns a matching set of nodes

Syntax: pnode.selectnodes ("pattern")

Tip: Pattern writing is similar to the value of the Select property of < Xsl:for-each >, which begins with "/"

Searches from the root of the document, traversing all nodes of the document with a "//" beginning table; Beginning

Represents the beginning of the parent node of the current node, and cannot have the above special characters if you want to search down from the current node.

Example: the number of elements with the same name as the current node within their parent element

Childnumber (This.selectnodes) (". /"+this.nodename+" [end ()]]. Item (0))

Number of elements in the current element whose name is "skill"

Childnumber (This.selectnodes ("Skill[end ()]"). Item (0))

20, selectSingleNode

Meaning: Similar to selectnodes, different returns only the first node of the match, not the set of nodes.

Syntax: Pnode.selectsinglenode ("pattern")

Example: the number of elements with the same name as the current node within their parent element

Childnumber (This.selectsinglenode) (". /"+this.nodename+" [end ()]))

Number of elements in the current element whose name is "skill"

Childnumber (This.selectsinglenode ("Skill[end ())")

21, text

Meaning: Returns the text content within the node and its subtree

Syntax: Pnode.text

Example: text content throughout a document

This.ownerDocument.text

The text content of the current element and its subtree

This.text

22, XML

Meaning: XML representation that returns the node and its descendants

Syntax: Pnode.xml

Example: XML content for the current document

This.ownerDocument.xml
