I'm looking to get this value 'B00DS4KJR4' enclosed in tags from a url by using file_get_contents() function in PHP. However, I'm failing to write the correct regex to find the value from this html source code the page:
<span class="a-text-bold">ASIN:
</span>
<span>B00DS4KJR4</span>
Can you help me to write the correct regex to find that particular value on the page ?
You can use a regular expression like the following also presented on Regex101 . This looks for a <span>
with any attributes, containing the string ASIN:
in the innerHTML followed by another <span>
and captures the contents of the second <span>
.
$html ='<span class="a-text-bold">ASIN:
</span>
<span>B00DS4KJR4</span>';
if (preg_match('/<span\s[^><]*>\s*ASIN:\s*<\/span>\s*<span>\s*([^><]*)\s*<\/span>/i', $html, $m)) {
$asin = $m[1];
print $asin;
}
preg_match_all('/<span>(.*)<\/span>/',$the_html,$the_result_array);
第一个span
与正则表达式不匹配,因为它具有类,其他的则写成<span>anything</span>
。
