Extract content with Xpath and data attribute

I need to extract the content of the following div tag which has the data-visible=”1″ attribute and contains the div id “line”.

<div class="line-name" id="line-10" data-visible="1">Need to extract</div>

I tried it like that, but I dont get any result.

$xpath->query('//*[contains(@id, "line")]//div[contains(@visible, "1")]');

What is the right way to extract the content with these both conditions and get the result:

Need to extract

Answer

Since this is a single element you should not use // after //*[contains(@id, "line")]. Also it is a data-visible attribute there, not visible.
You can use XPath expression like this:

'//div[contains(@id, "line") and @data-visible="1"]'

Or

'//div[contains(@id, "line")][@data-visible="1"]'
