specifics replace substring in string with php function -

In the lesson, I would like to change the div tag li . But not everyone is just some well defined. In this case, people who have the ID "tab- *" starts, I need to use the PHP function easily:

  & lt; Div id = "tab-141285" class = "my-class" & gt; & Lt; Div class = "my-subclass" & gt; & Lt; Div & gt; Advertising Ready Advertising & lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; Div id = "tab-85429" class = "my-class" & gt; & Lt; Div class = "my-subclass" & gt; & Lt; Div & gt; Advertising Ready Advertising & lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt;   
 Get this text  
  & lt; Li id = "tab-141285" class = "my-class" & gt; & Lt; Div class = "my-subclass" & gt; & Lt; Div & gt; Advertising Ready Advertising & lt; / Div & gt; & Lt; / Div & gt; & Lt; / Li & gt; & Lt; Li id = "tab-85429" class = "my-class" & gt; & Lt; Div class = "my-subclass" & gt; & Lt; Div & gt; Advertising Ready Advertising & lt; / Div & gt; & Lt; / Div & gt; & Lt; / Li & gt;   
 Can you advise me?  
 Thanks   
 
 
 Regular expressions for parsing HTML are not sufficient I Any regex trying to use will be fragile. Instead, I suggest this.  
 This idea is:  
 
 all  & lt; Div & gt;  Find elements that start with a  id  attribute  "tab -"   // div [starts (@id, " Tab - ")]   
 For each of them, a new  & lt; Li & gt;  element.  
 All  & lt; Div & gt;  
 
 
 
 
 
 
    
  Li>  >.   
 Because there is no basic element in your string, we will dance a little bit before we put it in one and then make it again.  
 
 Example:  
  $ html = & lt; & Lt; & Lt; 'Html' & lt; Div id = "tab-141285" class = "my-class" & gt; & Lt; Div class = "my-subclass" & gt; & Lt; Div & gt; Advertising Ready Advertising & lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; Div id = "tab-85429" class = "my-class" & gt; & Lt; Div class = "my-subclass" & gt; & Lt; Div & gt; Advertising Ready Advertising & lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt; Html; $ Dom = new DOMDocument (); $ Dom- & gt; Load HTML ("& lt; div> $ html ", LIBXML_HTML_NOIMPLIED); $ Xpath = new DOMXPath ($ dom); $ Node = $ xpath- & gt; Query ('// div [Start-start ('id,' tab- "]] '); Foreign currency ($ node $ as node) {$ li = $ dom- & gt; Create element (' li ' ); While ($ node-> attribute-> length) {$ li-> SetAttiInode ($ node-> Attribute-> Item (0));} while ($ node- & First Child) {$ li-> Epand Chલ્ડ ($ node-> First Child);} $ Node-> parentNode-> Infant ($ li, $ node);} $ Html = ''; Foreign currency ($ dom- & gt; document element-> child nodes $ node form) {$ html. $ = $ Dom-> Save HTML ($ node);} $ Html echo; < / Code>  
 
 OU Put:  
  
 li id ​​= "tab-141285" class = "my-class"> 
 & gt; Lt; div & gt; Ads Ready for Advertising & lt; / div & gt; & lt; / div & gt; & lt; / li & gt; & lt; li id ​​= "tab-85429" class = "My-class"> 
 
 Ad ready to ad & lt; / div & gt; & lt; / div & gt;
