ExpressionDOMParser (Geotools modules 31-SNAPSHOT API)

Object
- ExpressionDOMParser

```
public final class ExpressionDOMParser
extends Object
```
parses short sections of gml for use in expressions and filters. Hopefully we can get away without a full parser here.

  - expression
```
public Expression expression(Node root)
```
    parses an expression for a filter.
    
    Parameters:
    
    root - the root node to parse, should be an filter expression.
    
    Returns:
    
    the geotools representation of the expression held in the node.

```
public Geometry gml(Node root)
```
  - coords
```
public List<Coordinate> coords(Node root)
```
    Parses a dom node into a coordinate list.
    
    Parameters:
    
    root - the root node representation of gml:coordinates.
    
    Returns:
    
    the coordinates in a list.
