encodePath

public static String encodePath(String path,
                                String separator,
                                String enc)

Parameters:

path - path to encode

separator - "." (dot) or "/", it will be not encoded if found

enc - charset

Returns:

the path encoded

decodePath

public static String decodePath(String path,
                                String enc)

decode a path (ex. %D0%9D%D0%B0.%B2%D0%BE%D0%BB%D0%BD)

Parameters:

path - path to decode

enc - charset

Returns:

the path decoded

createExportPath

public static String createExportPath(String path)

Prior to 4.5 Magnolia used to produce export xml filenames where the / (slash) separating sub nodes was replaced by a dot. Since 4.5, Magnolia enables dots in path names, therefore dots which are part of the node name have to be escaped by doubling them. I.e. given a path like this /foo/bar.baz/test../dir/baz..bar, this method will produce .foo.bar..baz.test.....dir.baz....bar.

revertExportPath

public static String revertExportPath(String exportPath)

The opposite of createExportPath(String). I.e. given a path like this .foo.bar..baz.test.....dir.baz....bar, this method will produce /foo/bar.baz/test../dir/baz..bar.
