19, SelectNodes
Meaning: The given style matching is applied to the current node and returns a match collection.
Syntax: pnode.selectnodes ("pattern")
Tip: Pattern's writing and
Depart from the root of the document; "//" starts all the nodes of the document; ".."
Indicates that from the parent node of the current node; if you want to search from the current node, you can't have the above special characters.
Example: Number of elements with the same name with the current node in their parent elements
ChildNumber (this.selectnodes ("../" this.nodeename " [end ()] "). Item (0))
Number of elements of the current element name "skill"
ChildNumber ("Skill [end ()]"). Item (0)) 20, Selectsinglenode
Meaning: Similar to SelectNodes, different returns only the first node, not the gathering collection
Syntax: pnode.selectsinglenode ("pattern")
Example: Number of elements with the same name with the current node in their parent elements
ChildNumber (this.selectsinglenode ("./" this.nodeename " [end ()] "))
Number of elements of the current element name "skill"
ChildNumber (this.selectsinglenode ("Skill [end ()]"))
21, Text
Meaning: Return to the text content with its subtree
Syntax: pnode.text
Example: text content in the entire document
this.ownerDocument.text
Current element and its subtree text content
this.Text
Twenty-two, XML
Meaning: return node and its descendants XML
Syntax: pnode.xml
Example: the XML content of the current document
this.ownerDocument.xml

Learn the XSL style method in this issue, you can use the XSL element
The XML is the same as DHTML (dynamic HTML), and these nodes are objects, and these objects are hierarchical, and the root node begins constitutes a hierarchical tree structure, which forms a document object model DOM. Through the properties of the object, the method reaches the purpose of the access control XML node.
We don't intend to explain in detail one by one here, because this can be written into a more than one tutorial, we will discuss some common methods first, in order to have a general understanding of the object method of the DOM.
Note: From this issue, all examples no longer provide complete source code. If you don't understand, please read the seven phases in front of the previous group and do it.
First, End ()
Meaning: Returns the last element in the collection.
Example: Output last resume
Assume that the XML file format is:
...
or
Second, INDEX ()
Meaning: Returns the position of the element in the collection, the return value is an integer, where the first element returns 0
Example: Return to three resumes
Resume [index () $ l $ 3]
Note: Index () is related to the parent element, see the case:
Returns the first
X / y [index () = 0] or x / y [0]
Third, Nodename ()
Meaning: Returns the name of the element, ie the marking name
Example: Select any elements, if its name (ie, the tagname) is equal to "name"
* [nodename () = "name"] or * [name]
Fourth, Number ()
Meaning: Convert value into numerical form, if not numerical, return empty, required parameters
Example: Jeff Weiner (AGE)? 0-year-old resume (Resume)
Resume [Number (AGE) $ LT $ 30] or Resume [AGE $ LT $ 30]
Five, nodetype ()
Meaning: Return the node type, resulting in a value. The following is a list of return values:
Node type node type value node character form description
ELEMENT1 "ELEMENT"
Element Attribute 2 "Attribute"
Markup-Delimited Region of Text 3 "TEXT"
Processing Instruction 7 "Processing_instruction"
Comment8 "comment"
Document Entity9 "Document"
Sixth, value ()
Meaning: Returns the value of elements or attributes
Example: Value () is the default method of the element or attribute, the following representation is equivalent
Name! Value () = "name" with name = "name"
@ attr = "attribute_value" with @ attr = "attribute_value"
Note: @ is a property prefix, @ attr representation is attribute ATTR
7. Attribute ()
Meaning: Returns a collection of all attribute nodes, equivalent to "@ *"
Example: Looking for all Resume elements, the value of at least one property is satisfied is "ABC"
Resume [$ ATTRIBUTE () = "ABC"] or resume [$ any $ @ * = "abc"] Look for all Resume elements, meets at least one child element with a property of "ABC"
Resume [$ ANY $ * / attribute () = "abc"] or resume [$ any $ * / @ * = "abc"]
Eight, comment ()
Meaning: Returns all comment nodes
Example: for example
ResMe [$ any $ comment () = "Qi Xi's resume"]
Represents looking for a comment statement
Elements
Nine, cdata ()
Meaning: Returns a collection of nodes of all CDATA types
Example: for example
Resume [$ any $ cdata () = "Qi Xi's resume"]
Indicates looking for the following statement (must be a direct sub-node)
Elements
Ten, node ()
Meaning: Returns a collection of all nodes other than root nodes and attribute nodes in the current context environment, equivalent
"* | Pi () | comment () | text ()"
Example: Looking for all Elements Resume, the name of its last node is "Skill"
Resume [Node () [end ()]! nodename () = "skill"]
Find the first node of all resume elements: resume / node () [0]
11. TextNode ()
Meaning: Returns a collection of nodes of all text types
Example: Find the second text node of each P element
P / TextNode (1) or P! TextNode (1)
Twelve, text ()
Meaning: Returns all sets of nodes indicating the text string, equivalent to "cdata () | textNode ()";
The content of this issue will be introduced, and another function date () has an error in my machine, making the browser automatically shut down, and a function PI () I have not found an appropriate application method, I don't introduce it. Using the script in XSL in the next period.
