XML Signature (also called XMLDSig, XML-DSig, XML-Sig) defines an XML syntax for digital signatures and is defined in the W3C recommendation XML Signature Syntax and Processing. Functionally, it has much in common with PKCS #7 but is more extensible and geared towards signing XML documents.
In the table below, the column "ISO 8859-1" shows how the file signature appears when interpreted as text in the common ISO 8859-1 encoding, with unprintable characters represented as the control code abbreviation or symbol, or codepage 1252 character where available, or a box otherwise. In some cases the space character is shown as ␠.
XML Signature: an XML syntax for digital signatures; XML for Analysis: data access in analytical systems, such as OLAP and Data Mining; XML pipeline: a language expressing how XML transformations are connected together; XML-RPC: a remote procedure call protocol which uses XML to encode its calls and HTTP as a transport mechanism
XPath is widely used in other core-XML specifications and in programming libraries for accessing XML-encoded data. XQuery (XML Query) is an XML query language strongly rooted in XPath and XML Schema. It provides methods to access, manipulate and return XML, and is mainly conceived as a query language for XML databases. XML Signature defines ...
XAdES-B-LT (Signature with Long Term Data), Certificates and revocation data are embedded to allow verification in the future even if their original source is not available. XAdES-B-LTA (Signature with Long Term Data and Archive timestamp), By using periodical timestamping (e.g. each year) compromising is prevented which could be caused by ...
One of the purposes of an electronic signature is to secure the data that it is attached to it from being modified. This can be done by creating a dataset that combines the signature with its signed data or to store the detached signature to a separate resource and then utilize an external process to re-associate the signature with its data.
Beautiful Soup is a Python package for parsing HTML and XML documents, including those with malformed markup. It creates a parse tree for documents that can be used to extract data from HTML, [3] which is useful for web scraping. [2] [4]
In SGML, HTML and XML documents, the logical constructs known as character data and attribute values consist of sequences of characters, in which each character can manifest directly (representing itself), or can be represented by a series of characters called a character reference, of which there are two types: a numeric character reference and a character entity reference.
