That's a bit convoluted way to do what you probably want to accomplish. It's better to just pick the text you want instead of the entire page's content. Give the span that contains the number an id:

<td><span id="stock">5</span> <b>Stock</b><br /></td>

Then target the span specifically:

document.getElementById( 'stock' ).innerText = '11';

var settotal = document.querySelector("[class='pcs']");
settotal.value = document.getElementById( 'stock' ).innerText;

Although depending on what you're doing it'd be better to not use document contents as a data store at all:

var stock = 11;
document.getElementById( 'stock' ).innerText = stock;

var settotal = document.querySelector("[class='pcs']");
settotal.value = stock;
