OFXAggregate Class

Properties   Methods   Events   Config Settings   Errors  

The OFXAggregate class supports parsing of XML aggregates that can be retrieved from other classes.

Syntax

class inebank.OFXAggregate

Remarks

The OFXAggregate class supports simple XML aggregate traversal functionality. Simply set the aggregate property to the value received from any aggregate property of any class in the package (e.g. the TxAggregate property from BankStatement or CCStatement). You can then use xpath to walk the Document Object Model (DOM) tree.

Remarks

xpath implements a subset of the XML XPath specification, allowing you to point to specific elements in the XML documents.

The path is a series of one or more element accessors separated by '/'. The path can be absolute (starting with '/') or relative to the current xpath location.

The following are possible values for an element accessor:

'name'A particular element name
name[i]The i-th subelement of the current element with the given name
[i]The i-th subelement of the current element
[last()]The last subelement of the current element
[last()-i]The subelement located at the last location minus i in the current element
name[@attrname="attrvalue"]The subelement containing a particular value for a given attribute (supports single AND double quotes)
..The parent of the current element

When xpath is set to a valid path, x_element points to the name of the element, with x_parent, x_namespace, x_prefix, x_child_name, x_child_namespace, x_child_prefix, x_child_x_text, and x_text providing other properties of the element. The attributes of the current element are provided in the x_attributes_name, x_attributes_namespace, x_attributes_prefix, and x_attributes_value properties.

build_dom must be set to True prior to parsing the document for the xpath functionality to be available.

Example (Setting XPath):

Document rootXML.XPath = "/"
Specific ElementXML.XPath = "/root/SubElement1/SubElement2/"
i-th ChildXML.XPath = "/root/SubElement1[i]"

def set_x_text(value: str) -> None: ...

x_text = property(get_x_text, set_x_text)

Default Value

""

Remarks

The current element is specified via the xpath property.

config Method

Sets or retrieves a configuration setting.

Syntax

def config(configuration_string: str) -> str: ...

Remarks

config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

has_xpath Method

Checks whether a certain XPath exists inside the aggregate.

Syntax

def has_xpath(xpath: str) -> bool: ...

Remarks

Used when there is no assurance that a certain XPath exists inside an aggregate.

on_error Event

Information about errors during data delivery.

Syntax

class OFXAggregateErrorEventParams(object):
  @property
  def error_code() -> int: ...

  @property
  def description() -> str: ...

# In class OFXAggregate:
@property
def on_error() -> Callable[[OFXAggregateErrorEventParams], None]: ...
@on_error.setter
def on_error(event_hook: Callable[[OFXAggregateErrorEventParams], None]) -> None: ...

Remarks

The on_error event is fired in case of exceptional conditions during message processing. Normally the class fails with an error.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

OFXAggregate Config Settings

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the config method.

XML Config Settings

CacheContent:   If true, the original XML is saved in a buffer.

This config controls whether or not the component retains the entire original XML in a buffer. This is used to retain the original XML as opposed to returning generated XML after parsing. The default value is true.

Charset:   Specifies the charset used when encoding data.

This setting specifies the character set used when encoding data. This value will also be used when creating the xml_declaration. The default value is "utf-8".

EOL:   The characters to use for separating lines.

If specified, the class will format the output XML, using the specified characters to separate multiple lines for nested XML elements. The default value is CRLF ("\r\n") .

This option should be combined with Indent for full effect.

ErrorOnEmptyAttr:   If true, passing an invalid attribute to the Attr method will throw an exception.

If an invalid attribute name is passed into the get_attr method, the method will return with an empty string if this is set to false, otherwise an exception is thrown.

ExtraNameChars:   Extra characters for the parser to consider as name characters.

Normally, the parser considers only the following characters as part of an XML identifier: 'A' through 'Z', 'a' through 'z', '0' through '9', and '.', '-', '_', ':'.

If you would like any other characters to be considered as name characters, you may set them as a string into this property.

ExtraSpaceChars:   Extra characters for the parser to consider as white space.

Normally, the parser considers only the following characters as white space: ' ' (space), '\t' (tab), '\ n' (newline), '\r' (carriage return), '\f' (form feed), and '\v' (vertical tab).

If you would like any other characters to be considered as white space, you may set them as a string into this property.

FlushOnEOL:   If set, the parser flushes its text buffer after every line of text.

The FlushOnEOL property controls whether on_characters events are fired for every line of the input text stream or not. Normally lines are buffered internally and delivered in batches, but if the FlushOnEOL flag is set, then a on_characters event is fired for each line.

IgnoreBadAttributePrefixes:   If true, bad (unknown) attribute prefixes are ignored.

Normally a trappable error is generated when an unknown attribute prefix is encountered. This setting suppresses the error. The default value is True.

IgnoreBadElementPrefixes:   If true, bad (unknown) element prefixes are ignored.

Normally a trappable error is generated when an unknown element prefix is encountered. This setting suppresses the error. The default value is True.

IncludeElementPrefix:   Whether to include the prefix in the element name.

This setting specifies whether to include the element prefix in the Element parameter of the on_start_element and on_end_element events.

If False (default) and validate is set to False the prefix is included in the Element parameter. For instance: ds:DigestMethod

If True and validate is set to False the prefix is not included in the Element parameter. For instance: DigestMethod

This setting is only applicable when validate is False.

IncludeXMLDeclaration:   Whether to include the XML declaration when writing XML.

This setting specifies whether the XML declaration is included in the output XML when writing XML. When set to True (default) the XML declaration will be included above any user specified XML. For instance:

<?xml version="1.0" encoding="utf-8" standalone="yes" ?>
...
Indent:   The characters to use for each indentation level.

If specified, the class will format the output XML, using the specified characters to denote each indentation level for nested XML elements.

This option should be combined with EOL for full effect.

Offset:   Current offset of the document being parsed.

This property is useful for determining the location of possible XML errors in the document.

Offset values start at 1.

PreserveWhitespace:   If true, leading and trailing whitespace in element text is preserved.

Normally the leading and trailing whitespace from an element's text is trimmed. When this property is set to true, this leading and trailing whitespace is preserved. The default value is false.

QuoteChar:   Quote character to use for attribute values.

By default, the class will use double quotes around attribute values. This property can be used to specify a different character such as a single quote.

StringProcessingOptions:   Defines options to use when processing string values.

This setting determines what additional processing is performed on string values fired through the on_characters event..

Note: This only applies when build_dom is False.

By default no additional processing is performed and the string is returned as is from the document. Strings may also be XML unescaped. Possible values are:

0 (none - default) No additional processing is performed.
1 Strings are XML unescaped.

For instance, when set to 0 the following text may be fired through the on_characters event:

&amp;&quot;&lt;&gt;

When set to 1 the following text would be fired through the on_characters event:

&"<>

Base Config Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

CodePage:   The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
  • Last Valid Build: The last valid build number for which the license will work.
MaskSensitive:   Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to True to mask sensitive data. The default is True.

This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

ProcessIdleEvents:   Whether the class uses its internal event loop to process events when the main thread is idle.

If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True.

SelectWaitMillis:   The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process.

If there are no events to process when do_events is called, the class will wait for the amount of time specified here before returning. The default value is 20.

UseInternalSecurityAPI:   Tells the class whether or not to use the system security libraries or an internal implementation.

When set to False, the class will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this setting to True tells the class to use the internal implementation instead of using the system security libraries.

On Windows, this setting is set to False by default. On Linux/macOS, this setting is set to True by default.

To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the OpenSSL Notes section.
