Method Details

buildXPath

public static String buildXPath(Object object)

Builds an absolute XPath expression for a given element or attribute within a JDOM XML structure. For each element that is not the root element, the XPath will also contain a position predicate. For all namespaces commonly used in MyCoRe, their namespace prefixes will be used.

Parameters:

object - a JDOM element or attribute

Returns:

absolute XPath of that object. In case there is a root Document, it will begin with a "/".

buildXPath

public static String buildXPath(Attribute attribute)

Builds an absolute XPath expression for the given attribute within a JDOM XML structure. For each element that is not the root element, the XPath will also contain a position predicate. For all namespaces commonly used in MyCoRe, their namespace prefixes will be used.

Parameters:

attribute - a JDOM attribute

Returns:

absolute XPath of that attribute. In case there is a root Document, it will begin with a "/".

buildXPath

public static String buildXPath(Element element)

Builds an absolute XPath expression for the given element within a JDOM XML structure. For each element that is not the root element, the XPath will also contain a position predicate. For all namespaces commonly used in MyCoRe, their namespace prefixes will be used.

Parameters:

element - a JDOM element

Returns:

absolute XPath of that element. In case there is a root Document, it will begin with a "/".

buildChildPath

public static String buildChildPath(Element element)

Builds a local XPath fragment as combined namespace prefix, local element name and position predicate

getNamespacePrefix

public static String getNamespacePrefix(Element element)

Returns the namespace prefix for this element, followed by a ":", or the empty string if no namespace prefix known.
