What should I do if I intercept the image name of a webpage?

There are a lot of code for capturing a webpage's image name: HTMLcode & lt; ahref = & quot;/index. php/Image: EISL_1.1.6.gif & quot; class = & quot; image & quot; title = & quot; Image: Capture of the Image name of a webpage by EIS
There are many Web page codes:

HTML code

  
Homogeneous pool for paving and stirring

Perforated flow channel homogeneous pool

Now I only need to get the image name (EISL 1.1.6.gif). What should I do?
What else can I do with regular expression truncation? Guidance
