How have you read the HTML file?
Can you post the code you have used?

The purpose of forums is generally to help with specific issues, not to write your code for you. Google can provide literally 1000's of examples or reading though files if you would just put forth the effort to look.

Finding the title tags is just a matter of using the String classes .indexOf() and .subString() methods. You would need to add some extra logic to account for case sensitive situations.

Code:

    String lineFromFile = "  blah blah Blah  <Title>Some Title</Title>";

    int startingPoint = lineFromFile.indexOf("<Title>");

    int endingPoint = lineFromFile.indexOf("</Title>");

    String pageTitle = lineFromFile.subString( (startingPoint +7) , ( endingPoint -1 ) );

Yes. Any thing in a String object can be parsed that way. There are specific API's for parsing XML though that may work better. You can Google for examples of the DOM and SAX APIs. One catch though, you can not assume that HTML will actually be written according to XML syntax standards, so those API's would not be a good option for HTML files.

I am not sure what you mean. If you are talking about reading in the text of the image tag it would be written out the same way it was written in. If you are talking about trying to read the acuatll binarry characters from an image file that would not work. First off I am not even sure how you would do that. Secondly Strings can only hold alpha-numeric data. i.e. numbers, letters, and punchation. It can not hold binary data.

If you want to manipulate or modify image files you should look into using the JAI (Java Advanced Image) API.
