bash - Using sed with html data -

I have some problems in using sed in conjunction with HALM I show the following sample problem:

  html = "& lt; html> gt; body & gt; enterlet & lt; / body & gt; & lt; html & gt;" Table = "& lt; table & gt; & lt; / table & gt;" Echo $ HTML | Sed -es / enter / $ table /  

This output:

  sed: -e expression # 1, char 18: unknown option for s '  
 If I leave  /  to  $ table , then it will be  and lt; Table & gt; & Lt; Table & gt;  This works fine. 
 
 Any ideas about fixing it? 
 
  Update  
 Here is a sample that can reproduce the problem: / P> 
 template.html: 
 
 < Code> & lt; Html & gt; & Lt; Body & gt; & Lt; Table & gt; Entries & lt; / Table & gt; & Lt; / Body & gt; & Lt; / Html & gt;  
 
 gui_template: 
 
  & lt; Tr & gt; & Lt; Td square = "td_tut_title" & gt; TITLE & lt; / Td> & Lt; Td square = "td_tut_content" & gt; & Lt; A href = "../ tutorial / GUI / FILENAME" & gt; & Lt; Img src = "img / bbp.png" alt = "bbp" /> & Lt; / A & gt; & Lt; / TD & gt; & Lt; / TR & gt;  
 
 genhtml.sh: 
 
  #! / Bin / bash html = `cat template.html` entries =` cat gui_template | Sed -e s / FILENAME / test / | Sed -e s / TITLE / title / `DELIM = $ '\ 377' resonance $ HTML | Sed -e "$ {DELIM} entrees $ {DELIM} $ ENTRIES $ {DELIM}"  
 
 Output: 
 
  ~ / htmlgen $ ./ Genhtml .sh sed: -e expression # 1, variable 14: aborted 's command'  
 

For example, use @ different delimiter

  $ HTML echo Sed -es @ Entry @ $ TABLE @
