xmerl_eventp - Simple event-based front-ends to xmerl_scan for processing
Contents
Data Types
option_list():
Options allow to customize the behaviour of the scanner. See also tutorial on customization
functions.
Possible options are:
{acc_fun,Fun}:
Call back function to accumulate contents of entity.
{continuation_fun,Fun}|{continuation_fun,Fun,ContinuationState}:
Call back function to decide what to do if the scanner runs into EOF before the document is
complete.
{event_fun,Fun}|{event_fun,Fun,EventState}:
Call back function to handle scanner events.
{fetch_fun,Fun}|{fetch_fun,Fun,FetchState}:
Call back function to fetch an external resource.
{hook_fun,Fun}|{hook_fun,Fun,HookState}:
Call back function to process the document entities once identified.
{close_fun,Fun}:
Called when document has been completely parsed.
{rules,ReadFun,WriteFun,RulesState}|{rules,Rules}:
Handles storing of scanner information when parsing.
{user_state,UserState}:
Global state variable accessible from all customization functions
{fetch_path,PathList}:
PathList is a list of directories to search when fetching files. If the file in question is not in
the fetch_path, the URI will be used as a file name.
{space,Flag}:
'preserve' (default) to preserve spaces, 'normalize' to accumulate consecutive whitespace and
replace it with one space.
{line,Line}:
To specify starting line for scanning in document which contains fragments of XML.
{namespace_conformant,Flag}:
Controls whether to behave as a namespace conformant XML parser, 'false' (default) to not otherwise
'true'.
{validation,Flag}:
Controls whether to process as a validating XML parser: 'off' (default) no validation, or
validation 'dtd' by DTD or 'schema' by XML Schema. 'false' and 'true' options are obsolete (i.e.
they may be removed in a future release), if used 'false' equals 'off' and 'true' equals 'dtd'.
{schemaLocation,[{Namespace,Link}|...]}:
Tells explicitly which XML Schema documents to use to validate the XML document. Used together with
the {validation,schema} option.
{quiet,Flag}:
Set to 'true' if xmerl should behave quietly and not output any information to standard output
(default 'false').
{doctype_DTD,DTD}:
Allows to specify DTD name when it isn't available in the XML document. This option has effect only
together with {validation,'dtd' option.
{xmlbase,Dir}:
XML Base directory. If using string/1 default is current directory. If using file/1 default is
directory of given file.
{encoding,Enc}:
Set default character set used (default UTF-8). This character set is used only if not explicitly
given by the XML declaration.
{document,Flag}:
Set to 'true' if xmerl should return a complete XML document as an xmlDocument record (default
'false').
{comments,Flag}:
Set to 'false' if xmerl should skip comments otherwise they will be returned as xmlComment records
(default 'true').
{default_attrs,Flag}:
Set to 'true' if xmerl should add to elements missing attributes with a defined default value
(default 'false').
xmlElement()=#xmlElement{}:Description
Simple event-based front-ends to xmerl_scan for processing of XML documents in streams and for parsing in
SAX style. Each contain more elaborate settings of xmerl_scan that makes usage of the customization
functions.
Exports
file_sax(Fname::string(),CallBackModule::atom(),UserState,Options::option_list())->NewUserState
Parse file containing an XML document, SAX style. Wrapper for a call to the XML parser xmerl_scan
with a hook_fun for using xmerl export functionality directly after an entity is parsed.
stream(Fname::string(),Options::option_list())->xmlElement()
Parse file containing an XML document as a stream, DOM style. Wrapper for a call to the XML parser
xmerl_scan with a continuation_fun for handling streams of XML data. Note that the
continuation_fun, acc_fun, fetch_fun, rules and close_fun options cannot be user defined using
this parser.
stream_sax(Fname,CallBack::CallBackModule,UserState,Options)->xmlElement()
Types:
Fname = string()
CallBackModule = atom()
Options = option_list()
Parse file containing an XML document as a stream, SAX style. Wrapper for a call to the XML parser
xmerl_scan with a continuation_fun for handling streams of XML data. Note that the
continuation_fun, acc_fun, fetch_fun, rules, hook_fun, close_fun and user_state options cannot be
user defined using this parser.
string_sax(String::list(),CallBackModule::atom(),UserState,Options::option_list())->xmlElement()
Parse file containing an XML document, SAX style. Wrapper for a call to the XML parser xmerl_scan
with a hook_fun for using xmerl export functionality directly after an entity is parsed.
