Get regex pattern

hi,

i want check "new incorrect id , label value element ref" in xml file using regex pattern ("\<ref id\=\"r|\"\>\r\n\<label\>|\<\/label\>") not worked.

regex regitem = new regex(@"\<ref id\=\"r|\"\>\r\n\<label\>|\<\/label\>"); please check regex , give me right pattern

for example: input: <ref-list id="appj.rl1"> <title>references for appendix j</title> <ref id="appj.r1"> <label>1</label> <citation citation-type="journal"> <ref id="appj.r4"> <label>4</label>  output: <ref id="appj.r1"> <label>1</label> <ref id="appj.r4"> <label>4</label>

            string filepath = @"c:\msdn\textfile.txt";             stringbuilder sbfiletext1 = new stringbuilder(file.readalltext(filepath));             string pat01 = @"(<ref.*.r\d.>)|(<label>.+<\/label>)";                                      matchcollection matches = regex.matches(sbfiletext1.tostring(), pat01);             foreach (match match in matches)             {                 console.writeline(match.value);             }              console.readkey();

output:

<ref id="appj.r1">
<label>1</label>
<ref id="appj.r4">
<label>4</label>
