XMLStarlet is a set of command line utilities (toolkit) to query, transform, validate, and edit XML documents and files using a simple set of shell commands in a way similar to how it is done with UNIX grep, sed, awk, diff, patch, join, etc commands.
The main difference is that XPath 1.0 was more relaxed about type conversion, for example comparing two strings ("4" > "4.0") was quite possible but would do a numeric comparison; in XPath 2.0 this is defined to compare the two values as strings using a context-defined collating sequence.
The Java package javax.xml.xpath has been part of Java standard edition since Java 5 [8] via the Java API for XML Processing. Technically this is an XPath API rather than an XPath implementation, and it allows the programmer the ability to select a specific implementation that conforms to the interface.
All elements in an XML document can contain sub elements, text and attributes. The tree represented by an XML document starts at the root element and branches to the lowest level of elements. Although there is no consensus on the terminology used on XML Trees, at least two standard terminologies have been released by the W3C :
Compared to XPath 2.0, XPath 3.0 adds the following new features: . Inline function expressions Anonymous functions can be created in an expression context. For example, the expression function ($ a as xs:double, $ b as xs:double) as xs:double {$ a * $ b} creates a function that returns the product of its two arguments.
A bounded wildcard is one with either an upper or a lower inheritance constraint. The bound of a wildcard can be either a class type, interface type, array type, or type variable. Upper bounds are expressed using the extends keyword and lower bounds using the super keyword. Wildcards can state either an upper bound or a lower bound, but not both.
Subsequently, over fifty implementations were created in various programming languages. The JSONPath Comparison Project lists many of these implementations and compares their behavior. [2] JSONPath is widely used in the Java ecosystem. [3] In 2024, the IETF published a standard for JSONPath as RFC 9535. [4]
These terms are references to terms in the XSLT 2.0 and XQuery 1.0 specification. A processor that is "schema-aware" is able to use a W3C XML Schema to define the data types of the various elements in the source XML document(s). These data types can then be used in XPath 2.0 and XSLT 2.0 commands. A "basic" XSLT 2.0 processor is unable to use ...
