xPointer

xPointer (extended-pointer elements) defines a set of attributes used by all those elements which use the TEI extended pointer mechanism to point at locations which have neither an SGML nor an XML ID.
Member of classes pointer  
Members xptr xref
Declaration 

<!ENTITY % a.xPointer '
      %a.pointer;
      doc ENTITY #IMPLIED
      from %extPtr; "ROOT"
      to %extPtr; "DITTO"'>
Attributes (In addition to global attributes and those inherited from pointer)
doc (document or file) specifies the document within which the desired location is to be found.
Datatype: ENTITY
Values: The name of a system entity associated with the document within which the target of this extended pointer is to be found, by default the current document.
Default: #IMPLIED
Example: 
<xptr doc="Chap2" from="id (e23)"/>
Note

The system entity named by this attribute must be declared in the DTD of the document containing the extended pointer. This should be declared as an external entity (parsed or unparsed); in an SGML document it may be declared as a SUBDOC entity, but this is not recommended.

from specifies the start of the destination of the pointer, as an expression in the TEI extended-pointer notation described in section 14.2.2 Extended Pointer Syntax.
Datatype: %extPtr;
Values: The value specified must be a valid expression in the TEI extended pointer notation defined in section 14.2.2 Extended Pointer Syntax.
Default: ROOT
Example: 






Note



If no value is specified, the target is the whole of the
document identified by the doc attribute.








to
specifies the endpoint of the destination of the pointer, as an
expression in the TEI extended pointer notation.




Datatype: %extPtr;






Values: The value specified must be a valid expression in the TEI
extended pointer notation defined in section 14.2 Extended Pointers.






Default: DITTO






Example: 
<xptr doc="OrbisPictus" from="id (animalia)" to="id (aquaticae)"/> 






Note



This attribute may only be supplied if the from
attribute is also supplied, in which case the destination is defined to
extend from the beginning of the location specified by the
from attribute, up to the end of that specified by the
to attribute.  It is an error for the to
attribute to specify a location whose end precedes the beginning of the
location specified by from; it is not an error for the scopes
to overlap.



If no value is specified, the target is the location specified by the
from attribute.












Note



This class belongs to the larger class pointer,
which means its elements also inherit the attributes of that class.
