使用特定文本PHP / XPath获取DOMElement

In PHP, i want to get all DOMElement containing a given text.

I get DOMText when $xpath->query("//text()[contains(., 'My String')]"), but which query must i perform for getting DOMElement instead?

    Use:

    (//*[text()
          [contains(., 'My String')]
       ]
     )[1]
    

    This selects the first element in the XML document that has a text node child that contains the string "My String".

    If it is guaranteed that only one such element exist, the above expression can be simplified to:

    //*[text()
          [contains(., 'My String')]
       ]
    

    If the elements you are looking for are guaranteed to have just a single text-node child, this expression can be simplified to:

    (//*[contains(., 'My String')])[1]
    

    respectively:

    //*[contains(., 'My String')]
