Catch string inside <a> tag without attributes

Question

I’m using gift in PHP to get the link of a tag , where through "getattribute" I can get that link by the href attribute.

Script by Crawler:

<?php
//carregamento da url
$dom = new DOMDocument();
libxml_use_internal_errors(true);
$dom->loadHTMLFile("http://www.linkdosite.com.br");

//pega somente os links
$links = $dom->getElementsByTagName('a');

//array que armazena o valor do crawler
$getLink = array();

$nlinks = 0;

foreach ($links as $pegalink) {

    //aqui pega cada link 
    $link = $pegalink->getAttribute('href');

    $termo = 'detalhe';//Termo para diferenciar dos demias links e pegar apenas os que contenham o termo

    $pattern = '/' . $termo . '/';//Padrão a ser encontrado na string $link

    if (preg_match($pattern, $link)) {
        $getLink[$nlinks] = $link;//Atribui o link ao array $getLink 

        echo $getLink[$nlinks]."<br>";//Imprime o link na tela

        $nlinks++;
    } 

}

Now, I also need to take the string that is inside the 'a' tag, I couldn’t find any example to help me solve this.

Block I picked up via Crawler:

<a href="link">
  <font style="font-size: 14px;" color="black" face="arial"><b>String que eu quero pegar</b></font>
</a>

Answer 1

To recover the value of the attributes / recover the string within a tag, do the following:

Example:

//carregamento da url
$dom = new DOMDocument();
libxml_use_internal_errors(true);
$dom->loadHTMLFile("http://google.com");

//pega somente os links
$links = $dom->getElementsByTagName('a');
$nlinks = 0;
foreach($links as $link) {
    // Recupera o texto dentro da tag
    echo $link->nodeValue, PHP_EOL;
    // Recupera o valor de um atributo
    echo $links->item($nlinks)->getAttribute('href'), PHP_EOL;
    $nlinks++;
}

In the PHP documentation, you have a contribution note with the example.

Can use strip_tags:

<?php
$text = '<a href="link">
  <font style="font-size: 14px;" color="black" face="arial"><b>String que eu quero pegar</b></font>
</a>
';
echo strip_tags($text);

See on Ideone

There are many ways to achieve the result you are looking for, with Domxpath (as said by @Lacobus and mentioned in the link I sent), can do with DOM... But this kind of thing(scraping) is very specific because it depends on the structure of the target page...

The most universal way would be the following:

<?php
$str = file_get_contents("/questions/229996/pegar-string-dentro-de-tag-a-sem-atributos");
$link = preg_match_all("/<a.*?>(.*?)<\/a\>/",$str, $matches);
print_r($matches[1]);
?>

If it doesn’t fit put the link to the site to see the structure...

Use the method evaluate() class DOMXPath:

<?php

$html = "<a href=\"link\"><font style=\"font-size: 14px;\" color=\"black\" face=\"arial\"><b>String que eu quero pegar</b></font></a>";

$dom = new DOMDocument();

$dom->loadXML($html);

$xp = new DOMXPath($dom);

$str = $xp->evaluate("string(/a)");

echo $str;
