PI: importxml
The purpose of an importxml PI is to produce an XML-fragment
and replace the PI with this fragment.
<?_wxt importxml xpath="" location="" transformation=""?>
The parameters are:
|
xpath (mandatory) |
Any xpath expression that identifies a nodeset that
will be treated like a XML-fragment. |
|
location mandatory, but optional in templates |
The URI of the file we want to import from. WXT will if necessary
attempt to tidy the source.
In templates the location parameter is usually skipped.
In this case all content files owned by the module in the script are
searched for appropriate content unless you reduce
the search with parameter id, see below.
|
|
transformation (optional) |
A transformation identifier
(see:
Transformation
).
This transformation may have parameters:
T(name='ole' address='halden'). This transformation is applied before
we attempt to extract with xpath.
|
|
encoding (optional) |
You can spesify expected encoding if you expect the import
to be without XML-header stating the encoding.
Default encoding is UTF-8 if not set otherwise in script (option: default-encoding).
|
|
id (optional) |
An id that match the id of the actual xmlimport
in script. Has only meaning when
this element has no location. One reason to use an id is
processing time if you have many contentfiles to a module.
Another reason may be that you have similar structures in different contentfiles and you
want to be selective.

<?_wxt importxml xpath="//div[@class='main']/*"?>
<?_wxt importxml

xpath="//div[@class='main']/*"?>
<?_wxt importxml uri="../quotes/q.xml"
