## Package wwsrc_app_xml

This package contains the HTTP interface to wwsrc_xmlgen which can be used for representing Portal Items, Pages and ACLs as XML documents. It also includes the APIs for generating the XSDs for these XML documents.
See the wwsrc_xmlgen package spec for details of the APIs to this package.
The package provides access to the following:
o HTTP API for XML for a portal Item, Page, ACL or Taxonomy
o HTTP API for an XSD for the XDB, Portal or Custom XML Schema Documents
It is designed to granted to PUBLIC and so can be used via the HTTP interface as an entrypoint to Portal for a content crawler.
For the crawler to be accessible via mod_plsql the following must be executed in SQL*Plus:
grant execute on wwsrc_app_xml to public
/

Scope:
  Public

Constant Detail

### BOOL_FALSE

    BOOL_FALSE constant pls_integer := 0

  Indicates False value for a True/False parameter in the URL. Some parameters passed in the URL take True/False values, this constant should be used as the value for False.

### BOOL_TRUE

    BOOL_TRUE constant pls_integer := 1

  Indicates True value for a True/False parameter in the URL. Some parameters passed in the URL take True/False values, this constant should be used as the value for True.

### DEBUG_CONSUMER

    DEBUG_CONSUMER constant varchar2(61) := 'SBR_QUEUE_PEEK'

  The name of the debug consumer used in sbr_queue_peek().

Function/Procedure Detail

### get

    procedure get(
        p_page_site_id in number default null,
        p_page_id in number default null,
        p_thing_site_id in number default null,
        p_thing_id in number default null,
        p_language in varchar2 default null,
        p_acl_uid in varchar2 default null,
        p_taxonomy_uid in varchar2 default null,
        p_xml_declaration in pls_integer default bool_true,
        p_include_metadata in pls_integer default bool_true,
        p_include_contents in pls_integer default bool_false,
        p_include_acls in pls_integer default bool_false,
        p_include_children in pls_integer default bool_true,
        p_depth in number default null,
        p_allprops in number default null
    )

  Return an XML representation of a resource to a client via mod_plsql. This function returns an XML representation of a resource (item, page or ACL) to a client (such as an XML enabled Web Browser) via htp calls. It can be called from a browser by entering a URL such as http://portal:port/pls/dad/schema.wwsrc_app_xml.get ?p_page_site_id=1&p_page_id=1&p_thing_id=12345
  If no parameters are passed in, the top level XML is returned with ChildURL elements containing URLs to all of the root pages of the page groups in the portal. This should be used as the starting point for all crawls.
  To request a page use:
  p_page_site_id, p_page_id
  To request an item use:
  p_page_site_id, p_page_id, p_thing_site_id, p_thing_id
  To request an ACL use:
  p_acl_uid
  To request a Taxonomy Element use:
  p_taxonomy_uid
  If only p_page_site_id and p_page_id are passed in then the XML representation of that page is produced, if the p_thing_site_id and p_thing_id are also passed in, then the XML representation of that item is produced.
  If p_language is not passed in, or the language is not available, then the default language of the page group is used to produce the XML. In the normal case, p_language and p_user would be null.
  If p_acl_uid is passed in, then the ACL identified by this parameter value is generated as a stand alone resource. The other parameters have no effect in this case.
  Note that if p_acl_uid is passed in, the p_page_site_id, p_page_id, p_thing_site_id, p_thing_id, p_taxonomy_uid are not permitted to be passed in (an internal exception will be raised). The other parameters will be ignored.
  If p_taxonomy_uid is passed in, then the Taxonomy Element identified by this parameter value is generated as a stand alone resource. The other parameters have no effect in this case.
  Note that if p_taxonomy_uid is passed in, the p_page_site_id, p_page_id, p_thing_site_id, p_thing_id, p_acl_uid are not permitted to be passed in (an internal exception will be raised). The other parameters will be ignored.
  Examples:
  1) Top Level call to start the crawl:

       http://portal:port/pls/dad/schema.wwsrc_app_xml.get

  2) Request for the XML for a specific page in the portal

       http://portal:port/pls/dad/schema.wwsrc_app_xml.get
       ?p_page_site_id=1&p_page_id=1

  3) Request for the XML for a specific item in the portal

       http://portal:port/pls/dad/schema.wwsrc_app_xml.get
       ?p_page_site_id=1&p_page_id=1&p_thing_id=12345

  4) Request for the XML for a specific item in the portal in French including the base64 encoded contents in the XML

       http://portal:port/pls/dad/schema.wwsrc_app_xml.get
       ?p_page_site_id=1&p_page_id=1&p_thing_id=12345&p_language=fr
       &p_include_xml=1

  5) Request for the XML for a standalone ACL

       http://portal:port/pls/dad/schema.wwsrc_app_xml.get
       ?p_acl_uid=P33_43674

  6) Request for the XML for a standalone Taxonomy Element

       http://portal:port/pls/dad/schema.wwsrc_app_xml.get
       ?p_taxonomy_uid=C0_30

  This method is also used for the Oracle Ultrasearch Specific Crawl returning XML in a DAV PROPFIND-like format.

        Depth 0, allprops 0 (href of current resource only)

        Depth 0, allprops 1 (href + metadata of current resource only)

        Depth 1, allprops 0 (href of current resource only + children)

        Depth 1, allprops 1 (href + metadata of current resource + children)

  If p_depth is null, then it is assumed to be a normal crawl request.
  For all requests:
  If any errors occur such as being unable to find a resource a 404 HTTP response (NOT FOUND) will be returned, and if the ESE user doesn't have enough permission to view the resource then a 403 HTTP response (PERMISSION DENIED) will be returned. If any unexpected exceptions occur a 500 HTTP response (INTERNAL SERVER ERROR) will be returned instead.
  The diagnostics log file should indicate what has gone wrong. 404s can be safely ignored (unless they occur all of the time), 403s mean that something is wrong with the Search Engine OID Authentication, 500s mean that an internal error has occurred in Portal whilst trying to provide the response.

  Parameters:
    `p_page_site_id` - The page site id
    `p_page_id` - The page id in the site
    `p_thing_site_id` - The thing site id (defaults to p_page_site_id)
    `p_thing_id` - The thing id of the item
    `p_language` - The language of the resource
    `p_acl_uid` - The ACL Identifier
    `p_taxonomy_uid` - The Taxonomy Identifier
    `p_xml_declaration` - True - include <? xml /> and <PortalContent> in XML False - don't include xml decl and <PortalContent>
    `p_include_metadata` - True - Include resource metadata False - Don't include resource metadata
    `p_include_contents` - True - Include tag with base64 encoded document contents False - Don't include document contents
    `p_include_acls` - True - Include Access Control List False - Don't include ACLs
    `p_include_children` - True - Include tags holding links to resource's children (for crawling) False - Don't include links to child resources
    `p_depth` - GET Depth (0 or 1 - Ultrasearch, null otherwise)
    `p_allprops` - For Ultrasearch, indicate whether to get the properties or just the links to the resources Use, 0 for no properties, 1 for all properties or null when not applicable (when p_depth is null this setting is ignored).
