toxmldemo's Introduction

toxmldemo

Small demo project which is written in GO and using NEX (improved LEX written in GO) and YACC approach to parse and convert to XML hierarchial data with the following format:

AmpQueryRepChoice {

   tradeRep {                                   

      tradeId {                                 
         tradeNo = 20160711-000000060000
         speedIndex = -1 
         \{\}
         fake1 = 123
         fake2 =
      }
      p1 = 098
      p2 = SDF
      p3 =
      p4 = RTY 
GHT
FRE
      statics {                                 
         chainId = 1                            
         buyOrderId {                           
            orderDate = 20160711                
            orderNo = 936                       
         }
         gol1 = qwdef
         gol2 = fsdsfsfsfsffs
         sellOrderId {                          
            so1 = 11111                         
            2222
            so2 =                               
         }
         gol3 = asdrethheaw
      }
   }
}

As you can see value of the properties can have many "words" which can be located on the different lines. There is no special delimiter to mark end of the property's value.

To use converter:

./toxmldemo <testdata/test.txt | xmllint --format -

Formatted XML, generated from the data above:

<?xml version="1.0"?>
<AmpQueryRepChoice>
  <tradeRep>
    <tradeId>
      <tradeNo>20160711-000000060000</tradeNo>
      <speedIndex>-1 \{\}</speedIndex>
      <fake1>123</fake1>
      <fake2/>
    </tradeId>
    <p1>098</p1>
    <p2>SDF</p2>
    <p3/>
    <p4>RTY GHT FRE</p4>
    <statics>
      <chainId>1</chainId>
      <buyOrderId>
        <orderDate>20160711</orderDate>
        <orderNo>936</orderNo>
      </buyOrderId>

        <so2/>
      </sellOrderId>
      <gol3>asdrethheaw</gol3>
    </statics>
  </tradeRep>
</AmpQueryRepChoice>
