How to click on the checbox from a list of checkboxes available inside a table using selenium - selenium

Question

I have been trying to click on the one particular checkbox, but all the checkboxes have the same tags and parameters inside. Only the text which is the name of the check box is varying, but unfortunately couldn't get that also to be used. Kindly do help me with this.
Html code:
<tr class="ng-scope" ng-repeat="group in groupsList | orderBy:'groupName'">
<td class="col-xs-4 ng-binding">
<input class="ng-scope ng-pristine ng-valid" type="checkbox" checklist-value="group" ng-model="checked"/>
Checkbox1 name
<br/>
</td>
</tr>
<!-- end ngRepeat: group in groupsList | orderBy:'groupName' -->
<tr class="ng-scope" ng-repeat="group in groupsList | orderBy:'groupName'">
<td class="col-xs-4 ng-binding">
<input class="ng-scope ng-pristine ng-valid" type="checkbox" checklist-value="group" ng-model="checked"/>
Checkbox2 name
<br/>
</td>
</tr>
<!-- end ngRepeat: group in groupsList | orderBy:'groupName' -->
<tr class="ng-scope" ng-repeat="group in groupsList | orderBy:'groupName'">
<td class="col-xs-4 ng-binding">
<input class="ng-scope ng-pristine ng-valid" type="checkbox" checklist-value="group" ng-model="checked"/>
Checkbox3 name
<br/>
</td>
</tr>
<!-- end ngRepeat: group in groupsList | orderBy:'groupName' -->
<tr class="ng-scope" ng-repeat="group in groupsList | orderBy:'groupName'">
<td class="col-xs-4 ng-binding">
<input class="ng-scope ng-pristine ng-valid" type="checkbox" checklist-value="group" ng-model="checked"/>
Checkbox4 name
Answers would be very much helpful and appreciated.
The xpaths I have tried:
//table/tbody/tr/td/input/following-sibling::text()
this is highlighting all the texts i.e names of checkboxes
//table/tbody/tr/td/input/following-sibling::br/preceding::text()='Checkbox name'
//table/tbody/tr/td/input/text()\[preceding::br and contains(../text(),'Checkbox name')\][1]

Answer 1

You should try using following xPath to select checkbox which is based on visible text :-
//td[contains(., 'Checkbox1 name')]/input

Answer 2

As you mentioned in the question, your purpose is to click on the checkbox.
You can select the input tag with the exact text:
//input[.="Checkbox1 name"]
or if you think there could be some extra spaces or text around the text, then you can use contains function:
//input[contains(., "Checkbox1 name")]

Answer 3

Also you can select by index:
element(by.tagName('table')).all(by.tagName('input')).get(INDEX).click();

Answer 4

Check this - protractor allows to search byCssContaining text -
http://www.protractortest.org/#/api?view=ProtractorBy.prototype.cssContainingText
It might be better than xPath.
Here is for your question:
function clickCheckboxByName (name) {
var checkbox = element(by.cssContainingText("input[type='checkbox']", name));
checkbox.click();
}
