I could identify the element is in iframe. Since I am new to selenium java, could you please help me with writing selenium java code to send card number including xpath identification?

You need to send the credit card to the input field after you switch to the iframe. There are several ways to build the xpath, like:
//v1 by containing name, probably the safest option
WebElement iframe_by_name_contains = driver.findElement(By.xpath("//iframe[contains(#name,'__privateStripeFrame')]"));
driver.switchTo().frame(iframe_by_name_contains);
//v2 by name - might not be goood if the 2445 is dynamic
WebElement iframe_by_name = driver.findElement(By.xpath("//iframe[#name='__privateStripeFrame2445']"));
driver.switchTo().frame(iframe_by_name);
//by title - might not be good in case that there are locales and the title is translated
WebElement iframe_by_title = driver.findElement(By.xpath("//iframe[#title='Secure card number input frame']"));
driver.switchTo().frame(iframe_by_title);
//get input field
driver.findElement(By.name("cardnumber")).sendKeys("4242424242424242");
For month/year and CVC
driver.switchTo().defaultContent();
WebElement iframe_by_title_mm_yy = driver.findElement(By.xpath("//iframe[#title='Secure expiration date input frame']"));
driver.switchTo().frame(iframe_by_title_mm_yy);
driver.findElement(By.name("exp-date")).sendKeys("03/24");
driver.switchTo().defaultContent();
WebElement iframe_by_title_cvc = driver.findElement(By.xpath("//iframe[#title='Secure CVC input frame']"));
driver.switchTo().frame(iframe_by_title_cvc);
driver.findElement(By.name("cvc")).sendKeys("123");

Simple way to display currency symbol in html2pdf for iText 7

I updated my code from iText 5.0 to iText 7 and html2pdf 2.0 according to this post. In earlier version rupee symbol was rendering properly, but because of css issue i changed the code. Now complete page is converting properly to pdf except rupee symbol.
Tried adding font in html style tag itself like * { font-family: Arial; }.
Changed value of rupee symbol from &#x20b9, ₹ and also added directly ₹ , but no use.
My Html:
<html>
<head>
<style>
* { font-family: Arial; }
</style>
<title>HTML div</title>
</head>
<body>

Java Code :
public class Test {
final static String DEST = "D://Workspace_1574973//POP//sample_12.pdf";
final static String SRC = "D://Workspace_1574973//POP//src//com//resources//test.html";
public static void main(String[] args) throws Exception {
createPdf(SRC, DEST);
}
public static void createPdf(String src, String dest) throws IOException {
HtmlConverter.convertToPdf(new File(src), new File(dest));
}
}
Earlier code, which was working with symbols.
log.info("Creating file start");
OutputStream file = new FileOutputStream(new File("font_check.pdf"));
Document document = new Document(PageSize.A4);
PdfWriter writer = PdfWriter.getInstance(document, file);
document.open();
InputStream is = new ByteArrayInputStream(fileTemplate.getBytes());
XMLWorkerHelper.getInstance().parseXHtml(writer, document, is);
document.close();
file.close();
log.info("Creating file end");
Is there any simple approach to achieve this, with minimal and optimized code ?
Because I've to generate thousands of pdf in one go, So the performance should not affect.
Please let me know, if anyone achieved this through latest version.
Edit : Also how to set particular paper type in this like A6, A3, A4 etc.

Hope you are not mad, because I don't have reputation to write simple comments... so I'll post a full answer instead. I parse HTML for my work, and I read SO sometimes. There is a lot on the subject regarding UTF-8 here. Most software systems support the "greater than char #256" (UTF-8) codes - for instance the Indian Rupee Symbol. However, most of the time the programmer has to include a specific request for such a desired behavior, explicitly.
In HTML, for instance - adding this line usually helps:
String UTF8MetaTag = "<meta http-equiv='Content-Type' content='text/html; charset=utf-8' />";
Anyway, not having used HTMLToPDF - I might not be the right guy to post answers to your questions - but, because I have dealt with UTF-8 foreign language characters for three years, I know that setting a software setting to handle the 65,000 or so chars is usually VERY EASY, BUT ALSO ALWAYS VERY MANDATORY.
Here is an SO post about using HTMLToPDF and UTF-8 to handle Japanese Kanji characters. Most likely, it should handle all UTF-8, but that is not a guarantee.
HTML2PDF support for japanese language(utf8) is not working
Here are a few posts about it using HTML2PDF in PHP:
Converting html 2 pdf (php) using hebrew returns "???"

How to determine encoding of an ByteArrayOutputStream?

I need to convert ByteArrayOutputStream to String but I can't figure out the encoding. Please help ? I tried Using ICUJ library but It only works for input stream. A conversion from byte array to input stream is also fine.
Here's a sample of what I'm getting using the default encoding. Clearly the new lines are not supposed be there.

I tried Using ICUJ library but It only works for input stream.
You can get the byte array from the ByteArrayOutputStream, and then wrap it in a ByteArrayInputStream ... and pass that to the ICUJ method.
(Bear in mind that there is a chance that ICUJ will intuit the wrong encoding. Or that the bytes might not represent text in any known encoding.)

It won't much help but java.nio.charset.CharsetDecoder has a detectedCharset() method to auto identify charset of character encoded bytes. But unfortunately current impl of CharSetDecoder in Java SE7 (the one that is received by calling the method Charset.newDecoder()) is not an auto detecting charset decoder so calling detectedCharSet() method throws UnsupportedOperationException.

Regarding the Link / text / image that stays static even when the webpage is scrolled

are there any Java script or any sample available for the Link / text / image that stays static even when the webpage is scrolled.
I am looking for something similar to the one on the bottom left side of the webpage borders(Helpful?, "Yes", "No").

Try this code this may help you. but this code required lot more css and javascript code to make this same as ehow.
<style>
.mainDiv {
height: 1000px;
border: solid 1px #000000;
}
.fixDiv {
height: 250px;
width: 20px;
border: solid 1px #000000;
position: fixed;
margin-top: 200px;
}
</style>
<html>
<body>
<div class="fixDiv">h e l p f u l l? Yes No</div>
<div class="mainDiv">Gaurav</div>
</body>
</html>

This can be done using simple css
create a style for div with id="poll" and give this style
div#poll {
position: fixed;
left: 0;
top: 100px;
}
<div id="poll">
<img src="image.jpg" alt="image" class="contimage" border="0"/></div>
This div will be shown in the left side of the window

Creating CSS from a HTML file

I have an html file which contains many elements:
<div>
<div id="imgElt11289447233738dIi15v" style="BORDER-RIGHT: 0px; BORDER-TOP: 0px; Z-INDEX: 1; LEFT: 795px; BORDER-LEFT: 0px; WIDTH: 90px; CURSOR: auto; BORDER-BOTTOM: 0px; POSITION: absolute; TOP: 186px; HEIGHT: 93px" lineid="lineid" y2="279" y1="186" x2="885" x1="795">

As can be seen, 1 div has many divs in it. Now I want to create a css file that will contain all the styling of this html page (need not be same). Have to write something in java code. I have the DOM object of this file available to me.
Basically, I want all the styles to be removed from here and will be kept under a CSS file like for div with id = imgElt11289447233738dIi15v css will be:
#imgElt11289447233738dIi15v{BORDER-RIGHT: 0px; BORDER-TOP: 0px; Z-INDEX: 1; LEFT: 795px; BORDER-LEFT: 0px; WIDTH: 90px; CURSOR: auto; BORDER-BOTTOM: 0px; POSITION: absolute; TOP: 186px; HEIGHT: 93px}
I am don't till this part but since I don't know how many levels of hierarchy of elements will be there is there any way to do the same for all child elements as well?
I used the following code
public static Document getStyleInCSSfile(Document aoDoc, String aoPathToWrite, String aoFileName) throws ApplicationException {
String loValue = null;
String loID = null;
String lsContent = "";
Element loRoot = aoDoc.getRootElement();
List loTempElementList = loRoot.getChildren();
int liCounter;
for (liCounter = 0; liCounter < loTempElementList.size(); liCounter++) {
Element loTemplateEle = (Element) loTempElementList.get(liCounter);
String loId=loTemplateEle.getAttribute("id").getValue();
loID = loTemplateEle.getAttributeValue("id");
if(null != loID)
{
loValue = loTemplateEle.getAttributeValue("style");
if(loValue!=null && loValue.trim().length()>0)
{
loTemplateEle.removeAttribute("style");
lsContent = lsContent.concat("#"+loID+"{"+loValue+"}\n");
}
}
}
SaveFormOnLocalUtil.writeToFile(aoPathToWrite,aoFileName,lsContent);
return aoDoc;
}
Edit : got to know that some regular expression may help by getting a string of SAX parser object and and using regular expression on it... any idea? any one? how to implement it

is it effective to define a style for each single tag?
if i were you i'd checked if any other tag has the same style and if all elements with one style had the same 'tag_name' i'd used the following:
tag_name{text-transform:uppercase;text-align:center;}
and every element with this tag name (if its' style isn't set in any other way) would have this style.
if there's a lot of different tags with the same style:
.class_name{text-transform:uppercase;text-align:center;}
<tag class="class_name">content</tag>

I think you should use SAX instead of DOM. In SAX you can register the handler that is called every time the parser sees new tag, attribute etc. In this case every time you see attribute "style" you should extract its value to CSS file.
The next approach is using Digester from jakarta.apache.org. It uses SAX and allows XML configuration (see DigesterDigester) that maps your value object directly yo your XML document.
Absolutely different solution may made using unix shell commands like grep and sed. The preference to one of the solution depends on your system requirements and how often do you have to run this code. If it is one time transformation use unix shell scripting. If it must be something robust and change the pages on the fly use java solution.
