6 XML::DOM::CharacterData - Common interface for Text, CDATASections and
7 Comments
8
10 XML::DOM::CharacterData extends XML::DOM::Node
11
12 The CharacterData interface extends Node with a set of attributes and
13 methods for accessing character data in the DOM. For clarity this set
14 is defined here rather than on each object that uses these attributes
15 and methods. No DOM objects correspond directly to CharacterData,
16 though Text, Comment and CDATASection do inherit the interface from it.
17 All offsets in this interface start from 0.
18
19 METHODS
20 getData and setData (data)
21 The character data of the node that implements this interface. The
22 DOM implementation may not put arbitrary limits on the amount of
23 data that may be stored in a CharacterData node. However,
24 implementation limits may mean that the entirety of a node's data
25 may not fit into a single DOMString. In such cases, the user may
26 call substringData to retrieve the data in appropriately sized
27 pieces.
28
29 getLength
30 The number of characters that are available through data and the
31 substringData method below. This may have the value zero, i.e.,
32 CharacterData nodes may be empty.
33
34 substringData (offset, count)
35 Extracts a range of data from the node.
36
37 Parameters:
38 offset Start offset of substring to extract.
39 count The number of characters to extract.
40
41 Return Value: The specified substring. If the sum of offset and
42 count exceeds the length, then all characters to the end of the
43 data are returned.
44
45 appendData (str)
46 Appends the string to the end of the character data of the node.
47 Upon success, data provides access to the concatenation of data and
48 the DOMString specified.
49
50 insertData (offset, arg)
51 Inserts a string at the specified character offset.
52
53 Parameters:
54 offset The character offset at which to insert.
55 arg The DOMString to insert.
56
57 deleteData (offset, count)
58 Removes a range of characters from the node. Upon success, data
59 and length reflect the change. If the sum of offset and count
60 exceeds length then all characters from offset to the end of the
61 data are deleted.
62
63 Parameters:
64 offset The offset from which to remove characters.
65 count The number of characters to delete.
66
67 replaceData (offset, count, arg)
68 Replaces the characters starting at the specified character offset
69 with the specified string.
70
71 Parameters:
72 offset The offset from which to start replacing.
73 count The number of characters to replace.
74 arg The DOMString with which the range must be replaced.
75
76 If the sum of offset and count exceeds length, then all characters
77 to the end of the data are replaced (i.e., the effect is the same
78 as a remove method call with the same range, followed by an append
79 method invocation).
