public final class XMPPathParser extends Object
|Modifier and Type||Method and Description|
Split an XMPPath expression apart at the conceptual steps, adding the root namespace prefix to the first property component.
public static XMPPath expandXPath(String schemaNS, String path) throws XMPException
In the most verbose case steps are separated by '/', and each step can be of these forms:
The logic is complicated though by shorthand for arrays, the separating '/' and leading '*' are optional. These are all equivalent: array/* array/ array* array All of these are broken into the 2 steps "array" and "".
The value portion in the array selector forms is a string quoted by ''' or '"'. The value may contain any character including a doubled quoting character. The value may be empty.
The syntax isn't checked, but an XML name begins with a letter or '_', and contains letters, digits, '.', '-', '_', and a bunch of special non-ASCII Unicode characters. An XML qualified name is a pair of names separated by a colon.
schemaNS- schema namespace
path- property name
XMPException- Thrown if the format is not correct somehow.
