Regular Expression in Java for HTML pages
hi,
I need to parse an html web page to extract specific information from the tags in Java. For example,
<b>Species </b> Strain </td>
I need to look for the Strain info (Strain is variable in length) in the page. The whole web page is stored as a huge string. I need a regular expression that can help me identify all the Species and retrieve their corresponding strain info.
Does someone has a clue how to do this or can propose some clever string manipulation methods in Java.
Thank you.

Re: Regular Expression in Java for HTML pages
In general you have two options: the (possibly heavy) use of regular expressions (or other String functions) or the use of a specialized library like jsoup (an HTML parser, search on the web).Originally Posted by pari89
In either cases, you have to clearly know what are the precise rules to find/extract the text you want. For example: is "xyz" (what you want) always at end of <td> tag? Is there always a <b> tag before what you want? Is it possible that there is a <i> (or other) instead of <b>? Do you want only last word or all words at the end? Do you care about surrounding spaces?
