It all depends on what you want to achieve. It is usually better to use the DOM for parsing HTML/XML. In few occasions where you can't load it due to parsing errors, a regular expression may get you there, but it can also cause a lot of headaches. Some things just are not possible with a regular expression.

Suppose i want to find anchor tag ->href value only from large file set no of files

so is reliable to go with Dom / Regex.
because Regex is faster then Dom in text processing

Do a speed test and find out. Using the DOM will be more reliable.
