Symfony version(s) affected

6.1.0

Description

The parser fails to parse multi-line literal syntax in combination with tags.

See the example below.

It should be allowed. E.g. on you find this:

Example 2.23 Various Explicit Tags

---
not-date: !!str 2002-04-28

application specific tag: !something |
 The semantics of the tag
 above may be different for
 different documents.

How to reproduce

The following can be added to ParserTest.
The test will pass, which means the parser does not work correctly.

    public function testTaggedTextAsListItem() {
        $yml = <<<'YAML'
- !text |
  first line
YAML;

        $this->expectException(ParseException::class);
        $this->expectExceptionMessage('Unable to parse at line 3 (near "!text |").');
        $this->parser->parse($yml, Yaml::PARSE_CUSTOM_TAGS);
    }

Without the ->expectException I get this:

1) Symfony\Component\Yaml\Tests\ParserTest::testTaggedValuesAsListItems
Symfony\Component\Yaml\Exception\ParseException: Unable to parse at line 14 (near "!text |-").

Possible Solution

Fix somewhere in Parser.
I have not studied this class enough yet to propose anything better.
