修改XML以从结果中删除字符

Question

我有一个生成属性标记的xml：

<Entity ITEMTYPE="PipeRun">
  <Attribute ItemTagFormat="(TagPrefix)-(OperFluidCode)-(NominalDiameter)-(TagSequenceNo)-(PipingMaterialsClass)-(InsulThick)(InsulationSpec)" FixedLength="()()()(4)()()()" FillingString="()()()(0)()()()" Alignment="(Right)(Right)(Right)()()()()" ProgID="()(ValidateNomDiam.ForeignCalc)()()(PipeSpec.CommodityCodeValidator)(SmartPlantInsulList.SPForeignCalc)(ProgramInsulList.SPForeignCalc)" /> 
  </Entity>

（NominalDiameter）返回一个“格式为。即2”的值

有没有办法修剪返回的值，以便“不会显示在结果中。即2
