Querying Document Nodes

Many methods are available to help quickly locate specific Blade constructs within a document. The following demonstrates how we can quickly retrieve the inner content of all echo statements within a document:

 1<?php
 2 
 3use Stillat\BladeParser\Nodes\EchoNode;
 4use Stillat\BladeParser\Document\Document;
 5 
 6$template = <<<'BLADE'
 7    {{ $hello }} {{ $world }}
 8BLADE;
 9 
10 
11// Returns " $hello  $world "
12Document::fromText($template)
13    ->getEchoes()
14    ->map(fn(EchoNode $e) => $e->innerContent)
15    ->join('');

#Available Methods

The following methods are also available on all NodeCollection instances, in addition to the following node types:

Stillat\BladeParser\Nodes\Components\ComponentNode
Stillat\BladeParser\Nodes\DirectiveNode

Querying nodes on ComponentNode or DirectiveNode instances requires structural analysis. Node queries will be evaluated against each nodes list of children nodes.

If this is your intent, be sure to call the resolveStructures() method on the Document instance first.

#getNodes

Gets the document nodes.

Returns a NodeCollection instance containing the nodes that represent the parsed template.

1<?php
2 
3use Stillat\BladeParser\Nodes\NodeCollection;
4 
5public function getNodes(): NodeCollection;

#getEchoes

Returns all Blade echo nodes in the document.

Retrieves all Blade echo statements from the document. Echo nodes are created after parsing the following types of syntax:

Normal echo: {{ $variable }}
Triple echo: {{{ $variable }}}
Raw Echo: {!! $variable !!}

1<?php
2 
3use Stillat\BladeParser\Nodes\NodeCollection;
4 
5public function getEchoes(): NodeCollection;

Example Use

 1<?php
 2 
 3use Stillat\BladeParser\Document\Document;
 4 
 5$template = <<<'BLADE'
 6    {{ $variableOne }}
 7    {{{ $variableTwo }}}
 8    {!! $variableThree !!}
 9BLADE;
10 
11$doc = Document::fromText($template);
12 
13// Returns 3
14$echoCount = $doc->getEchoes()->count();

#getPhpBlocks

Returns all Blade php/endphp blocks within the document.

Retrieves all raw PHP blocks within the source document that were created using Blade's @php/@endphp directives.
Raw @php directives that contain arguments will not be converted to instances of PhpBlockNode, and will instead become instances of DirectiveNode.

1<?php
2 
3use Stillat\BladeParser\Nodes\NodeCollection;
4 
5public function getPhpBlocks(): NodeCollection;

Example Use

 1<?php
 2 
 3use Stillat\BladeParser\Document\Document;
 4 
 5$template = <<<'BLADE'
 6    @php
 7        $count = 1;
 8    @endphp
 9 
10        @php ($count++)
11 
12    @php
13        echo "The count is: {$count}";
14    @endphp
15BLADE;
16 
17$doc = Document::fromText($template);
18 
19// Returns 2
20$phpBlockCount = $doc->getPhpBlocks()->count();

#getPhpTags

Returns all PHP tags within the document.

PHP tags are created after parsing raw PHP regions within the source template. PHP tags will be created whenever the following types of PHP tags are encountered:

PHP Short Echo: <?= ?>
PHP Open: <?php ?>
If you are looking to retrieve PHP blocks created using Blade's @php @endphp directives you should refer to the getPhpBlocks method instead.
Note: The PHP short echo tags will be parsed even if short tags have been disabled in the PHP configuration.

1<?php
2 
3use Stillat\BladeParser\Nodes\NodeCollection;
4 
5public function getPhpTags(): NodeCollection;

Example Use

 1<?php
 2 
 3use Stillat\BladeParser\Document\Document;
 4 
 5$template = <<<'BLADE'
 6    <?php $count = 1; ?>
 7 
 8        The count is: <?= $count ?>
 9BLADE;
10 
11$doc = Document::fromText($template);
12 
13// Returns 2
14$phpTagCount = $doc->getPhpTags()->count();

#getVerbatimBlocks

Returns all verbatim blocks within the document.

Returns all valid @verbatim/@endverbatim regions within the source document. Unpaired verbatim directives that could not be converted into a valid VerbatimNode instance will either become part of the document's literal content (in the case of the @verbatim directive), or will become a standalone DirectiveNode (in the case of @endverbatim).

1<?php
2 
3use Stillat\BladeParser\Nodes\NodeCollection;
4 
5public function getVerbatimBlocks(): NodeCollection;

Example Use

 1<?php
 2 
 3use Stillat\BladeParser\Document\Document;

 7        {{ $hello }}
 8    @endverbatim

10    Content
11 
12    @verbatim
13        {{ $world }}
14    @endverbatim
15BLADE;
16 
17$doc = Document::fromText($template);
18 
19// Returns 2
20$verbatimCount = $doc->getVerbatimBlocks()->count();

#getLiterals

Returns all literal content nodes within the document.

Returns the source template's content that could not be parsed into a valid Blade construct. If a document contains no Blade code, the parser will return a single instance of LiteralNode.

1<?php
2 
3use Stillat\BladeParser\Nodes\NodeCollection;
4 
5public function getLiterals(): NodeCollection;

Example Use

 1<?php
 2 
 3use Stillat\BladeParser\Document\Document;

 7 
 8BLADE;
 9 
10$doc = Document::fromText($template);
11 
12// Returns 3
13$literalCount = $doc->getLiterals()->count();

#getDirectives

Returns all directives within the document.

Returns all directives from the source document. Some directive pairs, such as the @php/@endphp and @verbatim/@endverbatim pairs will not result in an instance of DirectiveNode, as they are handled by the parser directly.

2 
3use Stillat\BladeParser\Nodes\NodeCollection;

5public function getDirectives(): NodeCollection;
