<h2>What is XPath?</h2>
|
|
<p>XPath is a query language used for selecting nodes from XML and processing them.<br>
|
|
It may perform operations on strings, numbers and boolean values.<br></p>

|
|
<p><b>XPath 2.0 introduced many new features XQuery-cośtam:</b><br>
|
|
- Added support for all XML simple types<br>
|
|
- Many new functions (tripled instruction count)<br>
|
|
- All expressions evaluate to sequence<br>
|
|
- Introduces conditional expressions and for-loops<br>
|
|
</p>
|
|
<p><b>XPath 3.0</b><br>
|
|
- Dynamic function calls (function may be called without being referenced by name (find
|
|
function in collection and call)<br>
|
|
- Inline functions<br>
|
|
- Namespace literals - Namespace may be embedded into function name<br>
|
|
- Support for union types - collections containing elements of different types<br>
|
|
- Mapping operator - '!' performs evaluation for each element in sequence and
|
|
concatenates results<br>
|
|
- Introduced maps <br>
|
|
</p>
|
|
<p><b>XPath 3.1</b><br>
|
|
- New operator for function chaining '=>' <br>
|
|
- Introduced maps that store data in pair 'key:value' - 'map{ key : value, key : value
|
|
}'<br>
|
|
- Introduced arrays - they differ from sequences in that they can be nested 'array{1, 5, 7,
|
|
(10 to 20)}'<br>

The lang function returns true or false depending on whether the language of the context node as specified by xml:lang attributes is the same as or is a sublanguage of the language specified by the argument string. The language of the context node is determined by the value of the xml:lang attribute on the context node, or, if the context node has no xml:lang attribute, by the value of the xml:lang attribute on the nearest ancestor of the context node that has an xml:lang attribute. If there is no such attribute, then lang returns false. If there is such an attribute, then lang returns true if the attribute value is equal to the argument ignoring case, or if there is some suffix starting with - such that the attribute value is equal to the argument ignoring that suffix of the attribute value and ignoring case. <br>
