Get the list of object containing text matching a pattern

I'm currently working with the API Apache POI and I'm trying to edit a Word document with it (*.docx). A document is composed by paragraphs (in XWPFParagraph objects) and a paragraph contains text embedded in 'runs' (XWPFRun). A paragraph can have many runs (depending on the text properties, but it's sometimes random). In my document I can have specific tags which I need to replace with data (all my tags follows this pattern <#TAG_NAME#>)
So for example, if I process a paragraph containing the text Some text with a tag <#SOMETAG#>, I could get something like this
XWPFParagraph paragraph = ... // Get a paragraph from the document
System.out.println(paragraph.getText());
// Prints: Some text with a tag <#SOMETAG#>
But if I want to edit the text of that paragraph I need to process the runs and the number of runs is not fixed. So if I show the content of runs with that code:
System.out.println("Number of runs: " + paragraph.getRuns().size());
for (XWPFRun run : paragraph.getRuns()) {
System.out.println(run.text());
}
Sometimes it can be like this:
// Output:
// Number of runs: 1
// Some text with a tag <#SOMETAG#>
And other time like this
// Output:
// Number of runs: 4
// Some text with a tag
// <#
// SOMETAG
// #>
What I need to do is to get the first run containing the start of the tag and the indexes of the following runs containing the rest of the tag (if the tag is divided in many runs). I've managed to get a first version of that algorithm but it only works if the beginning of the tag (<#) and the end of the tag (#>) aren't divided. Here's what I've already done.
So what I would like to get is an algorithm capable to manage that problem and if possible get it work with any given tag (not necessarily <# and #>, so I could replace with something like this {{{ and this }}}).
Sorry if my English isn't perfect, don't hesitate to ask me to clarify any point you want.

Finally I found the answer myself, I totally changed my way of thinking my original algorithm (I commented it so it might help someone who could be in the same situation I was)
// Before using the function, I'm sure that:
// paragraph.getText().contains(surroundedTag) == true
private void editParagraphWithData(XWPFParagraph paragraph, String surroundedTag, String replacement) {
List<Integer> runsToRemove = new LinkedList<Integer>();
StringBuilder tmpText = new StringBuilder();
int runCursor = 0;
// Processing (in normal order) the all runs until I found my surroundedTag
while (!tmpText.toString().contains(surroundedTag)) {
tmpText.append(paragraph.getRuns().get(runCursor).text());
runsToRemove.add(runCursor);
runCursor++;
}
tmpText = new StringBuilder();
// Processing back (in reverse order) to only keep the runs I need to edit/remove
while (!tmpText.toString().contains(surroundedTag)) {
runCursor--;
tmpText.insert(0, paragraph.getRuns().get(runCursor).text());
}
// Edit the first run of the tag
XWPFRun runToEdit = paragraph.getRuns().get(runCursor);
runToEdit.setText(tmpText.toString().replaceAll(surroundedTag, replacement), 0);
// Forget the runs I don't to remove
while (runCursor >= 0) {
runsToRemove.remove(0);
runCursor--;
}
// Remove the unused runs
Collections.reverse(runsToRemove);
for (Integer runToRemove : runsToRemove) {
paragraph.removeRun(runToRemove);
}
}
So now I'm processing all runs of the paragraph until I found my surrounded tag, then I'm processing back the paragraph to ignore the first runs if I don't need to edit them.

How to enter characters one by one in to a text field in selenium webdriver?

How to enter characters one by one in to a text field in selenium webdriver? I have used the below code but it's not working
getDriver().findElement(By.id("PhoneNumber")).sendKeys(Keys.chord("9876544322"));
Can anybody suggest how to resolve this?

Here is how I am sending character by character using Selenium Webdriver (in Java). This way in the back-end, I verify at each letter press if the character exists in the input. Normal element.sendKeys() is not working well for me 2 out of 5 times - the last letter is missing, I guess something is buggy with Selenium Webdriver, I don't know. Try the code below, it works 100% of the time for me.
public void TypeInField(String xpath, String value){
String val = value;
WebElement element = driver.findElement(By.xpath(xpath));
element.clear();
for (int i = 0; i < val.length(); i++){
char c = val.charAt(i);
String s = new StringBuilder().append(c).toString();
element.sendKeys(s);
}
}
As you see, I get the value needed to be typed and in the for loop, I take each character, convert it to string and send it to textbox. Also, I have a search for xpath, you can change that to id, or classname, or whatever you want.

If you want to make your sendKeys more human like, I've used something like this:
private static void sendHumanKeys(WebElement element, String text) {
Random r = new Random();
for(int i = 0; i < text.length(); i++) {
try {
Thread.sleep((int)(r.nextGaussian() * 15 + 100));
} catch(InterruptedException e) {}
String s = new StringBuilder().append(text.charAt(i)).toString();
element.sendKeys(s);
}
}
It sends the keys with a 100ms delay, but only an average of 100ms. It creates a normal distribution with average 100ms and std. deviation 15ms.

sendKeys() does enter characters in sequence, but it can at times run quickly enough to be perceived as a copy/paste action. Though, it is in fact intended to simulate a user entering text by typing. Per the sendKeys() JavaDoc:
/** Use this method to simulate typing into an element, which may set its value. */
If you wanted to slow it down, you could make a method that accepts WebElement and String args, convert the String to charsequence[], then use a for loop and enter each index of the array in the .sendKeys() followed by a Thread.sleep(). This seems horribly inefficient, though, as sendKeys() recognizes Strings as charsequence[] (String is a charsequence[] in Java). Adding the Thread.sleep() will only slow your test needlessly.
Honestly, sendKeys() fits your described needs. It's the best way to simulate a user at a keyboard, it just does it really fast.

.chord() will press all keys simultaneously. Not very well suited for field input.
The .sendKeys() method will accept a String. Simply pass your input as such and have a go with it.
driver.findElement(By.id("element")).sendKeys("Field Input Text");

I created a Python function of the Java Selenium code.
Find attached below and tweak based on the elements you want to use:
def TypeInField(xpath, myValue):
val = myValue
elem = driver.find_element_by_xpath(xpath)
c = ""
for i in range(0, len(val)):
c += val[i]
elem.send_keys(c)
time.sleep(3)
elem.send_keys(Keys.ENTER)

I use this function in my test when I want to type a string letter by letter.
public void typeOnLetterByLetter(WebElement webElement, String value, long waitBetweenLetters, ChronoUnit unitTime) {
clear(webElement);
Arrays.asList(value.toCharArray()).forEach(letter -> {
typeOn(webElement, String.valueOf(letter));
pause(waitBetweenLetters, unitTime);
});
}
private void pause(long time, ChronoUnit unitTime) {
try {
Thread.sleep(Duration.of(time, unitTime).toMillis());
} catch (InterruptedException ignore) {
}
}

Here is how I did it in C#
public void TypeInFieldCharByChar(IWebElement element,string text)
{
var strBuilder = new StringBuilder();
for (int i = 0; i < text.Length; i++)
{
Thread.Sleep(100);
strBuilder.Append(text[i]);
element.SendKeys(strBuilder.ToString());
strBuilder.Clear();
}
}

Remove Hightlight matching String content

Ok, few days ago I made one post regarding to the remove of Hightlighted text in JTextArea:
Removing Highlight from specific word - Java
The thing is, that time I made one code to remove Hightlights macthing its size...but now I have a lot of words with the same size in my app and obviously the application isnt running right.
So I ask, Does anyone know a library or a way to do this removal macthing the content of each highlighted string?

You could write a method to get the text for a given highlighter:
private static String highlightedText(Highlight h, Document d) {
int start = h.getStartIndex();
int end = h.getEndIndex();
int length = end - start;
return d.getText(start, length);
}
Then your removeHighlights method would look like this:
public void removeHighlights(JTextComponent c, String toBlackOut) {
Highlighter highlighter = c.getHighlighter();
Highlighter.Highlight[] highlights = h.getHighlights();
Document d = c.getDocument();
for (Highlighter.Highlight h : highlights)
if (highlightedText(h, d).equals(toBlackOut) && h.getPainter() instanceof TextHighLighter)
highlighter.removeHighlight(h);
}

How many times a text appears in webpage - Selenium Webdriver

Hi I would like to count how many times a text Ex: "VIM LIQUID MARATHI" appears on a page using selenium webdriver(java). Please help.
I have used the following to check if a text appears in the page using the following in the main class
assertEquals(true,isTextPresent("VIM LIQUID MARATHI"));
and a function to return a boolean
protected boolean isTextPresent(String text){
try{
boolean b = driver.getPageSource().contains(text);
System.out.println(b);
return b;
}
catch(Exception e){
return false;
}
}
... but do not know how to count the number of occurrences...

The problem with using getPageSource(), is there could be id's, classnames, or other parts of the code which match your String, but those don't actually appear on the page. I suggest just using getText() on the body element, which will only return the page's content, and not HTML. If I'm understanding your question correctly, I think that is more what you are looking for.
// get the text of the body element
WebElement body = driver.findElement(By.tagName("body"));
String bodyText = body.getText();
// count occurrences of the string
int count = 0;
// search for the String within the text
while (bodyText.contains("VIM LIQUID MARATHI")){
// when match is found, increment the count
count++;
// continue searching from where you left off
bodyText = bodyText.substring(bodyText.indexOf("VIM LIQUID MARATHI") + "VIM LIQUID MARATHI".length());
}
System.out.println(count);
The variable count contains the number of occurrences.

There are two different ways to do this:
int size = driver.findElements(By.xpath("//*[text()='text to match']")).size();
This will tell the driver to find all of the elements that have the text, and then output the size.
The second way is to search the HTML, like you said.
int size = driver.getPageSource().split("text to match").length-1;
This will get the page source, the split the string whenever it finds the match, then counts the number of splits it made.

You can try to execute javascript expression using webdriver:
((JavascriptExecutor)driver).executeScript("yourScript();");
If you are using jQuery on your page you can use jQuery's selectors:
((JavascriptExecutor)driver).executeScript("return jQuery([proper selector]).size()");
[proper selector] - this should be selector that will match text you are searching for.

Try
int size = driver.findElements(By.partialLinkText("VIM MARATHI")).size();

caret position into the html of JEditorPane

The getCaretPosition method of JEditorPane gives an index into the text only part of the html control. Is there a possibility to get the index into the html text?
To be more specific suppose I have a html text (where | denotes the caret position)
abcd<img src="1.jpg"/>123|<img src="2.jpg"/>
Now getCaretPosition gives 8 while I would need 25 as a result to read out the filename of the image.

I had mostly the same problem and solved it with the following method (I used JTextPane, but it should be the same for JEditorPane):
public int getCaretPositionHTML(JTextPane pane) {
HTMLDocument document = (HTMLDocument) pane.getDocument();
String text = pane.getText();
String x;
Random RNG = new Random();
while (true) {
x = RNG.nextLong() + "";
if (text.indexOf(x) < 0) break;
}
try {
document.insertString(pane.getCaretPosition(), x, null);
} catch (BadLocationException ex) {
ex.printStackTrace();
return -1;
}
text = pane.getText();
int i = text.indexOf(x);
pane.setText(text.replace(x, ""));
return i;
}
It just assumes your JTextPane won't contain all possible Long values ;)

The underlying model of the JEditorPane (some subclass of StyledDocument, in your case HTMLDocument) doesn't actually hold the HTML text as its internal representation. Instead, it has a tree of Elements containing style attributes. It only becomes HTML once that tree is run through the HTMLWriter. That makes what you're trying to do kinda tricky! I could imagine putting some flag attribute on the character element that you're currently on, and then using a specially crafted subclass of HTMLWriter to write out until that marker and count the characters, but that sounds like something of an epic hack. There is probably an easier way to get what you want there, though it's a bit unclear to me what that actually is.

I had the same problem, and solved it with the following code:
editor.getDocument().insertString(editor.getCaretPosition(),"String to insert", null);

I don't think you can transform your caret to be able to count tags as characters. If your final aim is to read image filename, you should use :
HTMLEditorKit (JEditorPane.getEditorKitForContentType("text/html") );
For more information about utilisation see Oracle HTMLEditorKit documentation and this O'Reilly PDF that contains interesting examples.
