regex - Replacing the contents of a list of items using regular expressions -


given following string:

lorem ipsum dolor sit amet, consectetur adipiscing elit. nulla rhoncus ipsum eros tincidunt ultricies...  [menu] item 1|http://stackoverflow.com/1 item 2|http://stackoverflow.com/2 item 3|http://stackoverflow.com/3 [/menu]  lorem ipsum dolor sit amet, consectetur adipiscing elit. nulla rhoncus ipsum eros tincidunt ultricies...

i'm trying generate regular expression returns:

lorem ipsum dolor sit amet, consectetur adipiscing elit. nulla rhoncus ipsum eros tincidunt ultricies...  <ul> <a href="http://stackoverflow.com/1">item 1</a> <a href="http://stackoverflow.com/2">item 2</a> <a href="http://stackoverflow.com/3">item 3</a> </ul>  lorem ipsum dolor sit amet, consectetur adipiscing elit. nulla rhoncus ipsum eros tincidunt ultricies...

there 1 or more menu blocks in each string , unknown number of links within each block. i'm able swap whole block, falling on over replacing individual links within block.

is there way of doing in 1 or more regular expressions (i prefer avoid splitting string array if @ possible). i'm using vbscript, generic example useful.

one (a bit complicated) way it:

option explicit  dim g_reitem ' sorry, must global  class cremagic   private m_remenu   private sub class_initialize()     set m_remenu = new regexp     m_remenu.global     = true     m_remenu.ignorecase = true     m_remenu.multiline  = true     m_remenu.pattern    = "^\[menu\]([\s\s]+?)^\[/menu\]$"     set g_reitem = new regexp     g_reitem.global     = true     g_reitem.ignorecase = true     g_reitem.multiline  = true ' item 1|http://stackoverflow.com/1 ' <a href="http://stackoverflow.com/1">item 1</a>     g_reitem.pattern    = "^\s*([^|]+)\|(http:.+?)(\r)$"   end sub   public function replace(sinp)     replace = m_remenu.replace(sinp, getref("menurpl"))   end function end class  function menurpl(sm, sg1, npos, ssrc)   menurpl = "<ul>" & g_reitem.replace(sg1, getref("itemrpl")) & "</ul>" end function  function itemrpl(sm, sg1, sg2, sg3, npos, ssrc)   itemrpl = vbcrlf & "<a href=""" & sg2 & """>" & sg1 & "</a>" end function    dim sinp : sinp = join(array( _        "lorem ipsum dolor sit amet, consecte" _      , "" _      , "[menu]" _      , "item 1|http://stackoverflow.com/1" _      , "item 2|http://stackoverflow.com/2" _      , "item 3|http://stackoverflow.com/3" _      , "[/menu]" _      , "" _      , "[mune]" _      , "item 1|http://stackoverflow.com/1" _      , "item 2|http://stackoverflow.com/2" _      , "item 3|http://stackoverflow.com/3" _      , "[/mune]" _      , "[menu]" _      , "item 4|http://stackoverflow.com/4" _      , "[/menu]" _      , "" _      , "lorem ipsum dolor sit amet, consecte" _   ), vbcrlf)   wscript.echo sinp   wscript.echo "------------------"    dim oremagic : set oremagic = new cremagic   wscript.echo oremagic.replace(sinp)   wscript.echo "------------------"

output:

lorem ipsum dolor sit amet, consecte  [menu] item 1|http://stackoverflow.com/1 item 2|http://stackoverflow.com/2 item 3|http://stackoverflow.com/3 [/menu]  [mune] item 1|http://stackoverflow.com/1 item 2|http://stackoverflow.com/2 item 3|http://stackoverflow.com/3 [/mune] [menu] item 4|http://stackoverflow.com/4 [/menu]  lorem ipsum dolor sit amet, consecte ------------------ lorem ipsum dolor sit amet, consecte  <ul> <a href="http://stackoverflow.com/1">item 1</a> <a href="http://stackoverflow.com/2">item 2</a> <a href="http://stackoverflow.com/3">item 3</a> </ul>  [mune] item 1|http://stackoverflow.com/1 item 2|http://stackoverflow.com/2 item 3|http://stackoverflow.com/3 [/mune] <ul> <a href="http://stackoverflow.com/4">item 4</a> </ul>  lorem ipsum dolor sit amet, consecte ------------------
