| XPath | | public class XPath implements Cloneable(Code) | | The root of the parse tree for an XPath expression. This is a
participant in the Visitor Pattern [Gamma et al, #331]. You create
an XPath object (which parses an XPath expression into a parse
tree), create a Vistor object, and pass the visitor to the
XPath.accept method.

| Method Summary | |
| public Object | clone()
A one-level clone in which the steps list is cloned but not the steps objects themselves.
It is OK for different XPaths to share Steps because they are immutable. | | public static XPath | get(String xpathString)
Return the xpath parse-tree object for this expression.
This may be either a newly
created object or a cached copy. | | public static XPath | get(boolean isAbsolute, Step[] steps)
Create an XPath from some steps. | | public String | getIndexingAttrName()
Return the attribute name in a trailing [@attrName] predicate. | | public Enumeration | getSteps()
| | public boolean | isAbsolute()
| | public boolean | isStringValue()
| | public static boolean | isStringValue(String xpathString)
| | public String | toString()
|
| clone | | public Object clone()(Code) | | A one-level clone in which the steps list is cloned but not the steps objects themselves.
It is OK for different XPaths to share Steps because they are immutable.
|
| get | | public static XPath get(String xpathString) throws XPathException(Code) | | Return the xpath parse-tree object for this expression.
This may be either a newly
created object or a cached copy.
|
| get | | public static XPath get(boolean isAbsolute, Step[] steps)(Code) | | Create an XPath from some steps.
The value of steps.length must be >= 1
|
| getIndexingAttrName | | public String getIndexingAttrName() throws XPathException(Code) | | Return the attribute name in a trailing [@attrName] predicate.
For example if the Xpath expression was "/a/b[@p='pp']/c[@q]"
then the indexing attribute name would be "q"
|
| isAbsolute | | public boolean isAbsolute()(Code) | | Does this path begin with a '/' or '//' ?
|
| isStringValue | | public boolean isStringValue()(Code) | | Does xpath evaluate to a string values (attribute values or
text() nodes)
