Get content between two tags and then return full string

how can i get some text between each two tags(<tagname></tagname>) and after changed the text of these two tags i need the complete string along with changes.think,this is the java string content.

before change

"Lorem ipsum dolor <tagname>text to be changed 1</tagname> amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud <tagname>text to be changed 2</tagname> laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint <tagname>text to be changed 3</tagname> cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum."

after changed, should be like this

"Lorem ipsum dolor <tagname>text changed 1</tagname> amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud <tagname>text changed 2</tagname> laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint <tagname>text changed 3</tagname> cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum."

actually i need a method like this,

String getChangedString(String toBeChanged){
   //process
   return changedString;
}

how can i get this.

thanks.

There is a flawless string parsing based utility available in org.apache.commons.lang.StringUtils, below code worked perfectly for me.

String title = StringUtils.substringBetween(testHtml, "<title>", "</title>");
System.out.println("title:" + title); // good

I was looking for the same, maybe this question can help you, take a look: Java regex to extract text between tags

It uses a regular expression to get the text content between tags. In my case, I was interested on getting the text from the first tags found on my xml, not from each tags

Assuming that the tags are within an XML file, you should use one of the existing XML parsers such as DOM or SAX instead of reinventing the wheel.

String getChangedString(String toBeChanged){
   String changedString = toBeChanged;

   while (changedString.indexOf("<tagname>") >= 0)
   {
     changedString = changedString.substring(0, changedString.indexOf("<tagname>")) +
       "whatever replacement string" +
       changedString.substring(changedString.indexOf("</tagname>") + "</tagname>".length());
   }


   return changedString;
}
