<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>
|
|
Semantics legend:
|
|
<p>
|
|
"+" - 1 or more elements
|
|
</p>
|
|
<p>
|
|
"*" - 0 or more elements
|
|
</p>
|
|
<p>
|
|
"?" - optional element

<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>
