xquery4 1.6.12
these previous versions should be considered unusabl e due to the lack of proper parser implementation features. Versions 2.0 and above are a closer match to the standards.
See the version list below for details.
dotnet tool install --global xquery4 --version 1.6.12
dotnet new tool-manifest
dotnet tool install --local xquery4 --version 1.6.12
#tool dotnet:?package=xquery4&version=1.6.12
nuke :add-package xquery4 --version 1.6.12
xquery
Command-line XQuery 3.1/4.0 processor for .NET. Query XML documents from the terminal using the PhoenixmlDb XQuery engine.
Installation
dotnet tool install -g xquery4
Usage
# Query an XML file
xquery '//book/title' library.xml
# Count elements
xquery 'count(//item)' catalog.xml
# Read from a query file
xquery -f transform.xq input.xml
# Query a directory of XML files
xquery 'collection()//product[price > 50]' ./data/
# JSON output
xquery -o json 'map { "count": count(//item) }' data.xml
# Read from stdin
cat data.xml | xquery '//item/@name'
# Show execution plan
xquery --plan 'for $x in 1 to 10 return $x * $x'
# Show timing breakdown
xquery --timing '//item' large-catalog.xml

Six fixes, four of them found by running XSpec's 284-suite corpus against the engine. Two are
the reason this release exists: without them the XSLT engine cannot report XSpec results
correctly.
### `namespace-node()` matched every node kind
`ItemType` had no `Namespace` member, so the parser mapped `namespace-node()` to `ItemType.Node`
— the test that matches ANY node. `$x instance of namespace-node()` therefore answered true for
elements, attributes, text, comments and documents alike.
XSpec decides whether a result can be wrapped in a document node with:
$item instance of node()
and not($item instance of attribute() or $item instance of namespace-node())
With the second test always true, that predicate was always false. No result was ever wrapped,
so the context item for every `x:expect` predicate stayed a parentless element rather than a
document node. An assertion written as `//foo`, the idiomatic XSpec style, could never match,
and one written as `/foo` raised XPDY0050.
Measured against the XSpec corpus: 4 more suites run to completion, 64 more assertions pass.
### `xs:integer()` crashed on a value wider than `long`
`BigInteger` does not implement `IConvertible`, and the constructor's fallback called
`Convert.ToInt64`. The catch clauses covered `FormatException` and `OverflowException` but not
`InvalidCastException`, so a CLR message reached the user:
Unable to cast object of type 'System.Numerics.BigInteger' to type 'System.IConvertible'
The value came from `xs:unsignedLong`, which returns a `BigInteger` above `long.MaxValue` by
design — a producer and a type matcher that already agreed, with the constructor between them
disagreeing.
### `xs:integer` is unbounded
`xs:integer` has no upper bound in XSD, but the constructor capped it at `long` and reported
`FORG0001 ... value out of range` for values the type permits. `MatchesItemType` already
accepted a `BigInteger` for `ItemType.Integer`, so widening the constructor aligns it with the
rest of the engine rather than adding a representation. Literals wider than `long` now parse.
### `fn:trace` rendered the container, not the value
`fn:trace` interpolated its argument, so `ToString()` on a container answered with the CLR type
— `System.Object[]` rather than the sequence. A diagnostic that hides the value defeats its own
purpose. Adds `XdmShape.Render`.
### `except`, `union` and `intersect` did not say what the bad operand was
An operand of the except operator is not a node
That message repeats the error code and omits both facts a user needs: WHICH of the two operands,
and what it actually held. It is emitted from two separate throw sites, so it could not even
distinguish left from right. It now reads:
The left operand of the except operator is not a node: the string ''
Found while tracing an XSpec failure through four wrong hypotheses; the improved message
identified the value on the first run afterwards.
### The CLI aborted on a spec-defined error
`XQueryException`, the family raised by built-in functions, had no catch arm and fell to a
catch-all whose `throw` aborted the process. `xquery "xs:integer('nope')"` exited 134 with a
stack dump. It now reports `Runtime error [FORG0001]` and exits 3.
