I want to find a regx and occurrences of it in the page source using language Java. The value I am trying to search is as given in the program below. There might be one or more spaces between tags. I am not able to form a regx for this value. Can some one please help me to find the regx for this value? My program which checks regx is as given below-
String regx=""<img height=""1"" width=""1"" style=""border-style:none;"" alt="""" src=""//api.adsymptotic.com/api/s/trackconversion?_pid=12170&_psign=3841da8d95cc1dbcf27a696f27ccab0b&_aid=1376&_lbl=RT_LampsPlus_Retargeting_Pixel""/>";
WebDrive driver = new FirefoxDriver();
driver.navigate().to("abc.xom");
int count=0, found=0;
source = driver.getPageSource();
source = source.replaceAll("\\s+", " ").trim();
pattern = Pattern.compile(regx);
matcher = pattern.matcher(source);
while(matcher.find())
{
count++;
found=1;
}
if(found==0)
{
System.out.println("Maximiser not found");
pixelData[rowNumber][2] = String.valueOf(count) ;
pixelData[rowNumber][3] = "Fail";
}
else
{
System.out.println("Maximiser is found" + count);
pixelData[rowNumber][2] = String.valueOf(count) ;
pixelData[rowNumber][3] = "Pass";
}
count=0; found=0;

Hard to tell without the original text and expected result, but your Pattern
clearly won't compile as is.
You should single-escape double quotes (\"
) and double-escape special characters (i.e. \\?
) for your code and your Pattern
to compile.
Something in the lines of:
String regx="<img height=\"1\" width=\"1\" style=\"border-style:none;\" " +
"alt=\"\" src=\"//api.adsymptotic.com/api/s/trackconversion" +
"\\?_pid=12170&_psign=3841da8d95cc1dbcf27a696f27ccab0b" +
"&_aid=1376&_lbl=RT_LampsPlus_Retargeting_Pixel\"/>";
Also consider scraping markup with appropriate framework (i.e. JSoup for HTML) instead of regex.
