Finding exact match without knowing position

I have seen examples of finding matches when that string is duplicated on a page and you know the position of the intended target. I have a case where the position won’t always be known. In some cases, it might be the first found string, while in other cases, it might be the second or third because there is overlap with other strings that have additional text.

Is it possible to force an exact string match with xpath?:

    {
      "Command": "verifyElementPresent",
      "Target": "xpath=//*[@id=\"list\"]/tbody/tr/td[text()[contains(.,'FINDEXACTMATCH')]]/..//input[@type='checkbox']",
      "Value": "",
      "Description": ""
    },

td[contains(text(), “FINDEXACTMATCH”)]

Unfortunately, that is not working. In my test case of using the above, UI vision still ended up targeting the first element containing the text (ex: “FINDEXACTMATCH-MORETEXT”) rather than the exact match of only “FINDEXACTMATCH”.
