Java parsing Rich Text processing img Tags

Many projects need to be rich text to add content, like news ah, tourist attractions and so on, need to use rich text to add data, but how I found on this side two questions

1) How can I get the src image of a rich text?

2) Background upload with a relative path, the front-end display needs to be the most to the path

I'll take a look at the two ways to solve these problems.

1): How to get the rich text picture src? Very simple, just one tool

 Public StaticList<string>getimgstr (String htmlstr) {List<String> list =NewArraylist<>(); String img= "";        Pattern P_image;        Matcher M_image; //String regex_img = "]*?> "; //Image Link AddressString regex_img = "]*?> "; P_image=pattern.compile (regex_img, pattern.case_insensitive); M_image=P_image.matcher (HTMLSTR);  while(M_image.find ()) {//get  DataIMG =M_image.group (); //match src data in Matcher m = pattern.compile ("src\\s*=\\s*\"? *?) (\ "|>|\\s+)"). Matcher (IMG);  while(M.find ()) {List.add (M.group (1)); }        }        returnlist; }

You can get the following results

2) Background upload when using a relative path, the front-end display needs is the most to the path, below to see how we dynamically to modify the rich text of the IMG tag src, is also very simple, is a tool can

A jar called Jsoup is needed here, and the MAVEN project can be introduced directly.

<Dependency>            <groupId>Org.jsoup</groupId>            <Artifactid>Jsoup</Artifactid>            <version>1.11.2</version>        </Dependency>

Here is the tool class

 Public Staticstring Documentbody (String newsbody) {Element doc=jsoup.parsebodyfragment (newsbody). body (); Elements PNGs= Doc.select ("img[src]"); String Httphost= "Http://192.168.0.100";  for(Element element:pngs) {String Imgurl= Element.attr ("src"); if(Imgurl.trim (). StartsWith ("/")) {//will go to match the first character of the src relative path of our rich text picture, please note thatImgurl =httphost +Imgurl; Element.attr ("SRC", Imgurl); }        }      returnNewsbody =doc.tostring (); }

You can get the following results

Well, that's the solution to these two problems.

Don't like to spray!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
