public static String align(String targetStr, String paddingStr)
See above
public static String align(String targetStr, String paddingStr, String type)
The str:align function aligns a string within another string. The first argument gives the target string to be aligned. The second argument gives the padding string within which it is to be aligned. If the target string is shorter than the padding string then a range of characters in the padding string are repaced with those in the target string. Which characters are replaced depends on the value of the third argument, which gives the type of alignment. It can be one of 'left', 'right' or 'center'. If no third argument is given or if it is not one of these values, then it defaults to left alignment. With left alignment, the range of characters replaced by the target string begins with the first character in the padding string. With right alignment, the range of characters replaced by the target string ends with the last character in the padding string. With center alignment, the range of characters replaced by the target string is in the middle of the padding string, such that either the number of unreplaced characters on either side of the range is the same or there is one less on the left than there is on the right. If the target string is longer than the padding string, then it is truncated to be the same length as the padding string and returned.
- Parameters:
targetStr
- The target stringpaddingStr
- The padding stringtype
- The type of alignment
- Returns:
- The string after alignment
public static String concat(NodeList nl)
The str:concat function takes a node set and returns the concatenation of the string values of the nodes in that node set. If the node set is empty, it returns an empty string.
- Parameters:
nl
- A node set
- Returns:
- The concatenation of the string values of the nodes in that node set
public static String padding(double length)
See above
public static String padding(double length, String pattern)
The str:padding function creates a padding string of a certain length. The first argument gives the length of the padding string to be created. The second argument gives a string to be used to create the padding. This string is repeated as many times as is necessary to create a string of the length specified by the first argument; if the string is more than a character long, it may have to be truncated to produce the required length. If no second argument is specified, it defaults to a space (' '). If the second argument is an empty string, str:padding returns an empty string.
- Parameters:
length
- The length of the padding string to be createdpattern
- The string to be used as pattern
- Returns:
- A padding string of the given length
public static NodeList split(String str, String pattern)
The str:split function splits up a string and returns a node set of token elements, each containing one token from the string. The first argument is the string to be split. The second argument is a pattern string. The string given by the first argument is split at any occurrence of this pattern. For example:str:split('a, simple, list', ', ') gives the node set consisting of:If the second argument is omitted, the default is the string ' ' (i.e. a space).a simple list
- Parameters:
str
- The string to be splitpattern
- The pattern
- Returns:
- A node set of split tokens
public static NodeList tokenize(String toTokenize, String delims)
The str:tokenize function splits up a string and returns a node set of token elements, each containing one token from the string. The first argument is the string to be tokenized. The second argument is a string consisting of a number of characters. Each character in this string is taken as a delimiting character. The string given by the first argument is split at any occurrence of any of these characters. For example:str:tokenize('2001-06-03T11:40:23', '-T:') gives the node set consisting of:If the second argument is omitted, the default is the string ' ' (i.e. whitespace characters). If the second argument is an empty string, the function returns a set of token elements, each of which holds a single character. Note: This one is different from the tokenize extension function in the Xalan namespace. The one in Xalan returns a set of Text nodes, while this one wraps the Text nodes inside the token Element nodes.2001 06 03 11 40 23
- Parameters:
toTokenize
- The string to be tokenizeddelims
- The delimiter string
- Returns:
- A node set of split token elements
