I want to replace all the text nodes in a html text. I'll explain with an example: $html = "

<div>
    <p>
        text2 text2 word text2
        <span>abcd</span>
        text2 text2 word text2
    <p>
    this is a long, very long statement with punctuations.
</div>

Ben "<span>this is a long, very long statement with punctuations.</span>" ile "<span>text2 text2 word text2</span>" ile "text2 text2 word text2" yerine ve "this is a long, very long statement with punctuations." istiyor

Ne için aynı düzenli ifade olmalıdır?
