Handling Web Tables, Frames, and Dynamic Elements in Selenium Script – Selenium Tutorial #18

In last Selenium WebDriver tutorial we learned various commonly and routinely used Selenium WebDriver commands including important topics like handling iframe and exceptions in Selenium scripts.

Moving ahead in our comprehensive series of tutorials on Selenium, in this tutorial we would discuss about handling Web tables, iframe and dynamic elements which are essential part of any web project.

This tutorial consists of 3 different topics and their handling mechanisms in selenium script.

  1. Web Tables/HTML tables
  2. Frames
  3. Dynamic elements

#1) Web Tables/HTML Tables

In this module we will learn about the web tables or html tables in a web page, tags available in html and how to handle web tables dynamically.

Web tables are basically group of elements that are logically stored in a row and column format. It is used to organize similar information in a web page.

Below is an example of Html table:

Handling web tables in selenium

Below is the snippet of html structure of an html table:

Handling web tables in selenium 1

Below tags are generally defined in an html tables:

1.’table’ tag defines html table.
2.’tbody’ tag defines container for rows and columns.
3.’tr’ defines rows in an html table.
4.’td’/’th’ define column of an html table.

Find the details of a web table:

There are many ways we can handle a web table.

Approach #1:

Below is the xpath of one of the cell in html table. Let’s say “firstname”


tr[1] defines first row and th[1] defines first column.

If number of rows and columns are always constant, let’s say our html table will always have 5 rows and 3 columns.

for(int numberOfRows=1; numberOfRows<=5; numberOfRows++)
for(int numberOfCol=1; numberOfCol <=3; numberOfCol++)

Except row and column number, each component of xpath remains the same. So you can iterate using “for loop” for each row and column as mentioned above.

Approach #2:

First approach is best suitable for the table which doesn’t change its dimensions and always remains the same. Above approach will not be a perfect solution for dynamically changing web tables.

Let’s take above html table as an example:

WebElement htmltable=driver.findElement(By.xpath("//*[@id='main']/table[1]/tbody"));
List<WebElement> rows=htmltable.findElements(By.tagName("tr"));

for(int rnum=0;rnum<rows.size();rnum++)
List<WebElement> columns=rows.get(rnum).findElements(By.tagName("th"));
System.out.println("Number of columns:"+columns.size());

for(int cnum=0;cnum<columns.size();cnum++)

Step 1: First get the entire html table and store this in a variable ‘htmltable’ of type web element.

Step 2: Get all the rows with tag name ‘tr’ and store all the elements in a list of web elements. Now all the elements with tag ‘tr’ are stored in ‘rows’ list.

Step 3: Loop through each row and get the list of elements with tag ‘th’. ‘rows.get(0)’ will give first row and ‘findElements(By.tagName(“th”))’ will give list of columns for the row.

Step 4: Iterate using ‘columns.getsize()’ and get the details of each cell.

Note: Above approach will be best suitable if the table dimensions changes dynamically.

This concludes the topic how to handle web tables in selenium. Next we will learn about handling an element inside frame.

#2) Frames:

In this section we will learn about the frames in a web page and how to identify the frames. Also we will find out how we can handle a frame in selenium WebDriver.

Many developers like to place elements inside frame. Frame is just like a container where few elements can be grouped.

Identification of a frame:

Different ways to know if the element is present inside a frame or not

#1. Right click on the element. Check if “This Frame” option is available. If This frame option is available, it means that the element is inside a frame.


#2. View page source of the web page and check if any tag is available for ‘iframe’.

Handling iframes in selenium

Verify Number of frames in a webpage:

All the frames are having tag name as “iframe”.

List<WebElement> frameList=driver.findElements(By.tagName(“iframe”));

In above example: frameList will have all the list of frames and frameList.size() will give the number of frames.

Handling an element inside frame:

If an element is inside a frame then control has to switch to frame first and then start operating on the elements.

Step 1: To switch inside a frame:

driver.switchTo().frame(1); //pass frame number as parameter.
driver.switchTo().frame(“frame Name”); //pass frame name as parameter.
driver.switchTo().frame(“xpath of the frame”);

Step 2: After switching inside a frame selenium will be able to operate on elements.


Here, we have learned how to handle an element inside frame and next we will cover about the different ways to handle dynamic element.

#3) Dynamic elements:

In this section we will learn different ways to handle dynamic element and construct generic Xpath.

In few scenarios, element attributes change dynamically. It can be ‘id’, ’name’ etc.

Example: let’s say ‘id’ of a username field is ‘username_123’ and the xpath will be

//*[@id=’username_123′] but when you open the page again the ‘id’ of ‘username’ field might have changed and the new value may be ‘username_234’.

In this case the test will fail because the selenium could not find the xpath you have passed earlier as the id of the field has changed to some other value.

There are many approaches depending upon the type of problem:

Problem Type 1: If part of the attribute value changes.

Example: As in the above example, id value changes but few fields remains constant.
‘username_123’ changed to ‘username_234’ but ‘username’ always remained constant.

You can construct xpath as below:


‘contains’ is a java method which checks if id contains the substring username.
starts-with() checks if any attribute starts with “user”.

Problem Type 2: If entire value of the attribute changes dynamically.

Again in this case, there could be different approaches:

Handling Dynamic elements in selenium
For example: if id of ‘login’ field changes dynamically and there is no constant value to use contains method.

Solution: Use of sendKeys.
Selenium provides different api to use function keys. For example tab key, enter keys, F5 etc.

Step 1: Enter password

Step 2: Use key functions to navigate to element.


Web tables, frames and dynamic elements are essential part of any web project. It is always desirable to write effective code to handle web tables and dynamic elements.

Understanding the construction of generic xpath which is very helpful while handling dynamic elements. In case of a frame, your script has to switch the frame and then operate on the element.

Next tutorial #19: In next Selenium tutorial we will learn about types of exceptions and how to handle exceptions in java in Selenium scripts.

Please post your queries related to Web tables, frames and handling dynamic element if you have any.

In #1 Approach to find the data from web table.the xpath is not working which is as shown :

However, I checked it, it is td[1] NOT th[1].
In other words it should be:

#6 Naveen

Excellent solutions !!! Please keep posting on such new stuff in Selenium

#7 MAX

Table data can be fetched in another way…its quite simple for me….

WebDriver dr=new FirefoxDriver();

List td=dr.findElements(By.xpath(“//td”));
String data[]=new String[td.size()];
for(int i=0;i<td.size()-1;i++){
WebElement wel=td.get(i);
String x=data[i]=wel.getText();

#8 Monisha


Please clarify by below doubt.

I need to select a row in the table based on the value present in a particular cell. Currently, I am using xpath as driver.findElement(By.xpath(“//div//table[@id=”]/tbody[1]/tr[12]/td[1]”)); to select that particular row.

Is it possible to select the row by giving the value present in the particular cell instead of giving row id like tr[12]?

Please help.

#27 Ak

How to get Html table data which is not having Id, class name and having multiple tables divs using c#Selinium

#28 ak

first needs to traverse the table row and traverse row’s column saved it list now you can play with list and can get the particular cell value
//find the table
Arraylist tab =table.findElements(By.tagName(“tr”));

//store the table row’s in table_row object
ArrayList table_row =(ArrayList) table.findElements(By.tagName(“tr”));
//get the row count
int rowcount=table_row.size();
//traverse the row to get column
for(int row=1;row<rowcount;row++)
//store the row's colmun in row_column object

ArrayList row_column =(ArrayList) table_row.get(row).findElements(By.tagName(“td”));
//get the column size
int columncount=row_column.size();
System.out.println(row+”rows column count is”+columncount);
//traverse row’s column’s
//for(int col=0;col<columncount;col++)
//get the cell value
String cellValue=row_column.get(col).getText();


// if you want to reduce the table row's column
you can reduce the for loop condition statement
for(int row=1;row<rowcount;row++)
you can change the rowcount to actual need row_count

same for column
for(int col=0;col<columncount;col++)
change the columncount to actual need columncount
