例子如下: procedure FindAllZips(ANode: TXmlNode); var i: integer; AList: TXmlNodeList; begin AList := TXmlNodeList.Create; try // Get a list of all nodes named 'ZIP' ANode.NodesByName('ZIP', AList); for i := 0 to A
现Find方法返回的Index总是错误的,当时一阵郁闷,随手按下F1键,Find的Help文档展现眼前,对于该 函数是这样描述的: Locates the index for a string in a sorted list and indicates whether a string with that value already exists in the list. 在Note部分又再次强调: Only use Find with sorted lists. For...
