Method Detail

concatTextNodesXSLImpl

public static java.lang.String concatTextNodesXSLImpl(oracle.xml.parser.v2.XMLNodeList tree)

Concatenates the contents of all text() nodes in the given XML tree.

Parameters:

tree - XMLNodeList containing one element that represents the XML tree.

Returns:

String containing the contents of all text nodes in the given XML tree.

digestXSLImpl

public static java.lang.String digestXSLImpl(java.lang.String message,
                                             java.lang.String algorithm,
                                             java.lang.String output)

Perform a one-way hash on the given string and return either a hexadecimal or base64 representation of the hash.

Parameters:

message - String containing the message to perform the hash on.

algorithm - String indicating which digest algorithm to use.

output - HEX or BASE64.

Returns:

String containing the message hash.

maskXSLImpl

public static java.lang.String maskXSLImpl(java.lang.String input,
                                           java.lang.String mode,
                                           java.lang.String maskChar,
                                           int count)

Perform simple String masking operations.

This method can perform three types of masking operations:

• first: This mask type will mask the first N characters of the given intput string.
• last: This mask type will mask the last N characters of the given intput string.
• all: This mask type will mask the entire input string.

Parameters:

input - String containing the data that must be masked.

mode - String indicating the masking mode: first, last, all.

maskChar - String containing the masking character.

count - An int indicating the character count.

Returns:

String containing the masked data.

Return the named Java System Property.

Parameters:

property - String containing the name of the property that must be returned.

defaultVal - String containing a default value if the property does not exist.

Returns:

String containing the property value or the default value.
