According to [this document](https://docs.oracle.com/javase/7/docs/api/java/util/Properties.html#load(java.io.Reader), you should only need to escape : = and whitespace, so your .map file should be
volume\:\ 2<br>mute\:\ 0<br>=2
but are you sure that your item’s value is exactly "volume: 2<br>mute: 0<br>"? The MAP transform does not search and replace a larger string with the values in the .map file.
Here is a tiny Java program you can compile with javac Test.java and run by typing java Test . It will read test.map and print out what it mapped:
import java.io.FileReader;
import java.util.Properties;
public class Test {
public static void main(String [] args) {
Properties props = new Properties();
try {
props.load(new FileReader("test.map"));
props.list(System.out);
}
catch (Exception ex) {
ex.printStackTrace();
}
}
}
The rules for map files (from the above java.util.Properties document):
The key contains all of the characters in the line starting with the first non-white space character and up to, but not including, the first unescaped ‘=’, ‘:’, or white space character other than a line terminator. All of these key termination characters may be included in the key by escaping them with a preceding backslash character; for example,
:=
would be the two-character key “:=”. Line terminator characters can be included using \r and \n escape sequences. Any white space after the key is skipped; if the first non-white space character after the key is ‘=’ or ‘:’, then it is ignored and any white space characters after it are also skipped. All remaining characters on the line become part of the associated element string; if there are no remaining characters, the element is the empty string “”. Once the raw character sequences constituting the key and element are identified, escape processing is performed as described above.
As an example, each of the following three lines specifies the key “Truth” and the associated element value “Beauty”:
Truth = Beauty
Truth:Beauty
Truth :Beauty
As another example, the following three lines specify a single property:
fruits apple, banana, pear,
cantaloupe, watermelon,
kiwi, mango
The key is “fruits” and the associated element is:
“apple, banana, pear, cantaloupe, watermelon, kiwi, mango”
Note that a space appears before each \ so that a space will appear after each comma in the final result; the , line terminator, and leading white space on the continuation line are merely discarded and are not replaced by one or more other characters.
As a third example, the line:
cheeses
specifies that the key is “cheeses” and the associated element is the empty string “”.
Characters in keys and elements can be represented in escape sequences similar to those used for character and string literals (see sections 3.3 and 3.10.6 of The Java™ Language Specification). The differences from the character escape sequences and Unicode escapes used for characters and strings are:
Octal escapes are not recognized.
The character sequence \b does not represent a backspace character.
The method does not treat a backslash character, , before a non-valid escape character as an error; the backslash is silently dropped. For example, in a Java string the sequence “\z” would cause a compile time error. In contrast, this method silently drops the backslash. Therefore, this method treats the two character sequence “\b” as equivalent to the single character ‘b’.
Escapes are not necessary for single and double quotes; however, by the rule above, single and double quote characters preceded by a backslash still yield single and double quote characters, respectively.
Only a single ‘u’ character is allowed in a Uniocde escape sequence.
