Element events are issued whenever the XML parser
|
|
encounters start or end tags. There are separate handlers
|
|
for start tags and end tags.

|
Character data is roughly all the non-markup contents of
|
|
XML documents, including whitespace between tags. Note
|
|
that the XML parser does not add or remove any whitespace,
|
|
it is up to the application (you) to decide whether
|
|
whitespace is significant.

PHP programmers should be familiar with processing
|
|
instructions (PIs) already. <?php ?> is a processing
|
|
instruction, where <replaceable>php</replaceable> is called
|
|
the "PI target". The handling of these are
|
|
application-specific, except that all PI targets starting
|
|
with "XML" are reserved.

|
What goes not to another handler goes to the default
|
|
handler. You will get things like the XML and document
|
|
type declarations in the default handler.

<function>xml_set_external_entity_ref_handler</function>

|

|
|
This handler is called when the XML parser finds a
|
|
reference to an external parsed general entity. This can
|
|
be a reference to a file or URL, for example. See <link
|
|
linkend="example.xml-external-entity">the external entity
|
|
example</link> for a demonstration.
