How to select multiple checkboxes in selenium(java)?

I am trying to select all checkboxes whose value is matched to my value.
Code is working fine when the web page has no vertical scroll. But if web page has some more data then the checkbox is not selected as I want.
Here is my code-
List<WebElement> rselect = tagdis1.findElements(By.className("row-selection-checkbox"));
System.out.println("Row selection Size- " + rselect.size());
List<WebElement> record = driver.findElements(By.id("$ctrl.item.id"));
System.out.println("Size- " + record.size());
int DocNameCount = 0;
for (int j = 0; j < record.size(); j++) {
String Pname = record.get(j).getText();
System.out.println("Pdf name- " + Pname);
if (Pname.equals(docName + ".pdf")) {
// here total 4 records i get but able to click only on 3 records
System.out.println(j + " " + Pname);
rselect.get(j).click();
Thread.sleep(2000);
}
}

Please use scroll option in your operation,
/*
* By
* scroll to the element and wait
*/
public void scroll(By element){
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("arguments[0].scrollIntoView(true);",driver.findElement(element));
log.info("Scrolling down");
}

How to get value in the cell that included tagName is "td" or "mat-cell"

My table has tagName "td" and "mat-cell". I have implement source as below sample that just get the value of the cell that has tagName is "td".
How to I got data that included tagName is "td" or "mat-cell"?
WebElement table = driver.findElement(taskListTablexpath);
List<WebElement> rows = table.findElements(By.tagName("tr"));
int row_count = rows.size();
System.out.println("Total Row: " + row_count);
for (int row = 0; row < row_count; row = row + 2) {
**List<WebElement> columns = rows.get(row).findElements(By.tagName("td"));**
int columns_count = columns.size();
System.out.println("Number of cells In Row " + row + " are " + columns_count);
for (int column = 0; column < columns_count; column++) {
String celtext = columns.get(column).getText();
if (celtext == null)
continue;
System.out
.println("Cell Value of row number " + row + " and column number " + column + " Is " + celtext);
}
System.out.println("-------------------------------------------------- ");
}
}

There can be only one tag, if you want to match <td> elements which have mat-cell class attribute - you need to amend your selector to be something like:
./td[contains(#class,'mat-cell')]

Also be aware of Table class available via HtmlElements framework, it makes working with Tables inlcuding Angular Material tables much easier

findElements(By.Xpath(".//td | .//mat-cell"))

After selecting the second option from dropdown, the WebElement is still showing the record of first option

There is a dropdown list where each selection has a different URL under the dropdown buttons. Suppose when I select first option then it shows 10 hyperlink and select the second option it shows 5 hyperlinks, etc.
Problem - When I select the second option, it is still showing 10 hyperlinks instead of 5 and shows
org.openqa.selenium.StaleElementReferenceException: Element not found
in the cache - perhaps the page has changed since it was looked up
Select select = new Select(selectdropdown);
List<WebElement> options = select.getOptions();
int isize = options.size();
for (int i = 0; i < isize; i++)
{
String value = select.getOptions().get(i).getText();
driver.manage().timeouts().implicitlyWait(100, TimeUnit.SECONDS);
WebElement WebElementer = driver.findElement(By.xpath("//*[#id='content-inner']"));
List<WebElement> elementList = new ArrayList<>();
elementList = WebElementer.findElements(By.cssSelector("a[href]"));
System.out.println("Total number of links found" + elementList.size());
System.out.println("to check wheather link is working or not");
for (WebElement element : elementList)
{
try
{
System.out.println("URL: " + element.getAttribute("href").trim() + " returned "
+ islinkBroken(new URL(element.getAttribute("href").trim())));
}
catch (Exception exp)
{
System.out.println("At " + element.getAttribute("innerHTML")
+ " Exception occured -> " + exp.getMessage());
}
}
}

where you selecting the element ?? (C# syntax example)
IList<IWebElement> accountsDDL = driver.FindElements(By.XPath("//select[#id='yourSelectId']/option"));
for (int i = 1; i < accountsDDL.Count; i++)
{
new SelectElement(driver.FindElement(By.Name("yourSelectId"))).SelectByText(accountsDDL[i].Text); // Selecting the element
}
In java

I spent a little time cleaning up your code and added a few things. See if this works. As Leon said, I think one of the issues was that you didn't have code that actually changed the selected option.
Select select = new Select(selectdropdown);
for (int i = 0; i < select.getOptions().size(); i++)
{
select.selectByIndex(i); // you were missing this line?
// String value = select.getFirstSelectedOption().getText(); // this variable is never used
// driver.manage().timeouts().implicitlyWait(100, TimeUnit.SECONDS); // this doesn't do what you think it does
// I think this next line should work. I combined the two locators into one.
List<WebElement> elementList = driver.findElements(By.cssSelector("#content-inner a[href]"));
System.out.println("Total number of links found" + elementList.size());
System.out.println("to check wheather link is working or not");
for (WebElement element : elementList)
{
try
{
String href = element.getAttribute("href").trim();
System.out.println("URL: " + href + " returned " + islinkBroken(new URL(href)));
}
catch (Exception exp)
{
System.out.println("At " + element.getAttribute("innerHTML") + " Exception occured -> " + exp.getMessage());
}
}
}
Suggestion: It might be useful to you to add the selected option text to your exception message.

unable to get theaders

im currently having a problem in getting the headers title of a table to make a validation, it work great until column 6, because when it goes to next one which isn't visible the .getText() is blank. I no the xpath is correct.
public void getAndSaveDataOfTable (final String tabla) throws FileNotFoundException{
WebElement element = driver.findElement(By.xpath(tabla));
List<WebElement> elements = element.findElements(By.xpath("th"));
Assert.assertTrue(elements.size() > 1);
int cantelements = elements.size();
for (int i = 1; i <= cantelements; i++) {
String data = driver.findElement(
By.xpath(".//div[#class='ui-datatable-scrollable-header-box']//table/thead/tr/th["+ i + "]/span[1]")).getText();
System.out.println("EL nombre del encabezado " + i + " " + data);
datosFila.put(i, data);
}
So between column 7and 20 I can't get the text of the header.

If you are going to be using the JavascriptExecutor several times (you said your issue is on multiple columns 7-20) I would suggest you can optimize by running JS only once and then iterating through in Java, rather than running JS again for every operation. The JavascriptExecutor is slow, and you'll save whole seconds on the total test time by avoiding even 12+ extra JS executions.
// JavaScript to get text from tHeads
String getTheadTexts =
"var tHeads = []; " +
"for (i = o; i < 20; i++) { " +
"var cssSelector = 'div.ui-datatable-scrollable-header-box table thead tr th' + i + ' span:nth-of-type(1)'; " +
"var elem = document.querySelector(cssSelector); " +
"var elemText = ''; " +
"if ((elem.textContent) && (typeof (elem.textContent) != 'undefined')) { " +
"tHeads.push(elem.textContent); " +
"} else { " +
"tHeads.push(elem.innerText); " +
"} " +
"} " +
"return tHeads; ";
// Execute the JS to populate a List
List<String> tHeadTexts = (ArrayList<String>) js.executeScript(getTheadTexts);
// Do some operation on each List item
int i = 0;
for (String data: tHeadTexts){
System.out.println("EL nombre del encabezado " + i + " " + data);
datosFila.put(i, data);
i++;
}

I ran into what sounds like what you're running into. Take a look at my post on
WebElement getText() is an empty string in Firefox if element is not physically visible on the screen
I ended up solving it by using a little bit of JavaScript to columns "into view". Hopefully this helps you out.
private void scrollToElement(WebElement element){
((JavascriptExecutor) driver).executeScript("arguments[0].scrollIntoView(true);", element);
}

Get the Beginning Position Of a field

Hi Guys I am writing a code that reads a text file in this format:
City |First Name| Second Name|Last Name|
The output I currently have is :
Column 1 is 17--------City
Column 2 is 10--------First Name
Column 3 is 12--------Second Name
Column 4 is 9---------Last Name
I need the Begin Position Also Of each Field in the Text File for example:
Column 1 is 17--------City : Position 1
Column 2 is 10--------First Name: Position 18
Column 3 is 12--------Second Name: Position 31
Column 4 is 9---------Last Name: Position 44
Here Is the Code I currently Have. Is there a way to achieve This?
package stanley.column.reader;
import java.io.*;
public class StanleyColumnReader {
public static void main(String[] args) throws IOException {
System.out.println("Developed By Stanley Mungai");
File f = new File("C:/File/");
if (!f.exists()) {
f.createNewFile();
} else {
f.delete();
}
String [] files = f.list();
for (int j = 0; j < files.length; j++){
FileInputStream fs = new FileInputStream("C:/File/" + files[j]);
BufferedReader br = new BufferedReader(new InputStreamReader(fs));
String result = "_result";
BufferedWriter is = new BufferedWriter(new FileWriter("C:/File/" + files[j] + result + ".txt"));
for (int i = 0; i < 0; i++) {
br.readLine();
}
String line = br.readLine();
String[] split = line.split("|");
for (int i = 0; i < split.length; i++) {
int k = i + 1;
System.out.println("Calculating the size of field " + k );
is.write("Column " + k + " is " + split[i].length());
is.flush();
is.newLine();
}
}
System.out.println("Success");
System.out.println("Output Saved to C:/File");
}
}

You could do that with a bit more advanced regexp group matching and get the group start index. But might be overkill and too advanced considering the question.
But a quick simple way in your case that might work is to just use indexOf on the line.
That is change your output to include:
" Position "+(line.indexOf(split[i])+1)
As long as a last name, first name and city aren't repeated on the same line...
You hardly need to flush on each line by the way, I suggest to move it outside the loop.
The regexp solution:
//first declare the pattern once in the class
static final Pattern pattern = Pattern.compile("\\s*(.*?)\\s*\\|");
...
//instead of the split loop:
String line = "City |First Name| Second Name|Last Name| Foo |Bar |"; //br.readLine();
Matcher matcher = pattern.matcher(line);
int column = 1;
while (matcher.find(column == 1 ? 0 : matcher.end())) {
String match = matcher.group(1);
System.out.println("Column " + column + " is " + match.length() + "---" + match + ": Position " + (matcher.start() + 1));
column++;
}
Possibly, depending on the exact position you want, you might want to change (matcher.start()+1) to (matcher.start(1)+1)

IS this an assignment? Please tag it properly.
You haven't said whether the delimiters are "|" in the data too but seeing your code, I am assuming it is.
What I don't understand is how the position you mentioned for Column 3 is 31 and column 4 is 44? Column 3 should be 10+17+1 =28 and column 4 should be 10+17+12+1=40. If I am getting it wrong, you need to post your original data too.
String[] split = line.split("|");
int pos=1; //initial position
for (int i = 0; i < split.length; i++) {
System.out.println("Calculating the size of field " + (i+1));
is.write("Column " + (i+1) + " is " + pos+" : Position "+pos);
pos=pos+split[i].length+1; //starting position for next column data
is.flush();
is.newLine();
}
Or you could find position by using indexOf method : line.indexOf(split[i])+1

If I understand what you need. Maybe you can use the indexOf method. This brings you the first coincidence. After finding this, change the pipe for something different and call indexOf pipe in the next iteration again.
String line = br.readLine();
for (int i = 0; i < split.length; i++) {
System.out.println("Calculating the position " + line.indexOf("|") );
line[line.indexOf("|")] = ",";
}
