How to use ruby regexp to move xml tags in an xml document when they fall between ERB tags? -

i have word docx in document.xml file:

-<w:r><w:tab/>   <w:t><%= @grantor   </w:t></w:r> -<w:r w:rsidr="008e7a5b">   <w:t>1.upcase %>, manager </w:t></w:r> 

i need take xml tags out in between erb tags (<%= , %>) , place them behind closing erb bracket (%>).

move this:

  </w:t></w:r> -<w:r w:rsidr="008e7a5b">   <w:t> 

to end with:

-<w:r><w:tab/>   <w:t><%= @grantor1.upcase %>   </w:t></w:r> -<w:r w:rsidr="008e7a5b">   <w:t>, manager </w:t></w:r> 

i know not idea use regex's parsing xml, trivial. need loop through each set of erb tags, grab between first "<" , last ">" between erb tags, not rest of document...and move them behind %>. work fine because never put "<" or ">" in erb tags reason. of can't done in single regex, i'm not sure how go it. maybe regex /<%=.+%>/ (not sure how make multiline), loop through instances , run regex on each. i'm not sure how moving. newbie, appreciated.

i have word docx

that's first problem. deal plain text files.

but trivial

not true--at all.

i know not idea use regex's parsing xml

your text not valid xml anyway because contains < , > characters in content of tag, instance:

<w:t>   <%= @grantor </w:t> 

so whether xml parser can handle broken xml not certain.

here's more robust solution:

str = %q{ <%= "hello" %>  <w:r>   <w:tab/>   <w:t><%= @grantor</w:t> </w:r> <w:r w:rsidr="008e7a5b">   <w:t>1.upcase %>, manager</w:t> </w:r>  <%= "goodbye" %>  <w:r>   <w:tab/>   <w:t><%= @grantor</w:t> </w:r> <w:r w:rsidr="008e7a5b">   <w:t>2.downcase %>, manager</w:t> </w:r> }   str.gsub!(/<%= (.*?) %>/xms) |match|   erb_contents = regexp.last_match[1]   xml = ""    if erb_contents.gsub!(/< .* >/xms, "")     xml = regexp.last_match[0]   end    "<%=#{erb_contents}%>#{xml}" end  puts str  --output:--  <%= "hello" %>  <w:r>   <w:tab/>   <w:t><%= @grantor1.upcase %></w:t> </w:r> <w:r w:rsidr="008e7a5b">   <w:t>, manager</w:t> </w:r>  <%= "goodbye" %>  <w:r>   <w:tab/>   <w:t><%= @grantor2.downcase %></w:t> </w:r> <w:r w:rsidr="008e7a5b">   <w:t>, manager</w:t> </w:r>
