XPath

(XML PATH) A sublanguage in an XSL style sheet that is used to identify XML elements for processing. It is also used to calculate numbers and manipulate strings. XPath and XSLT expressions are intertwined. For example, although XPath can reference a variable, the variable must be created and given a value in XSLT. XPath syntax is somewhat like the directory addressing in Unix, which uses a slash for the root directory as well as the separator between hierarchies. See XSL and XQuery.

Tudor [23] proposed an optimization model for XML data processing based on a heuristic algorithm to extract data from XPath views.
In other words, it is possible for users to access and extract data with either SQL or XPath from heterogeneous models (Relational and XML case), so they do not need to control the use of the two different types of query languages to retrieve data on different database systems.
The goal in Karma is to enable data-sawy users (for example, spreadsheet users) to model sources, shielding them from the complexities of the underlying technologies (for example, SQL, SPARQL, graph patterns, XSLT, XPath, and so on).
Some of these technologies are SOAP [4], WSDL [5], UDDI [6], XML Schema [7], document object model (DOM) Application Program Interface (API) [8], Extensible Style sheet Language (XSL) [9], XSL Transformations (XSLT) [10], XML Path language (XPath) [11] and many more.
Threat Protection: Protect APIs against unintentional or intentional attacks and abuse including Denial-of-Service, SQL and JavaScript or XPath Query attacks.

(1) When new documents are entered into the system, the Absolute Document XPath Indexing (ADXPI) [34] indexer parses and analyzes the name of each element and its position to build inverted lists for each index in this system.

Even protected by WS-Security, a SOAP-based Web service was still vulnerable to various types of newly found attacks including XML external entity attacks, XML bombs, malicious SOAP attachment, and XPath injections (Jaamour, 2005).
