我有一个XML文件....现在我想根据我在NSIS SCRIPT中的要求解析它并将数据存储到结构数组中。 

  This is my XML:-

  <?xml version="1.0" ?>

请任何人帮我解析并存储到NSIS脚本中的结构数组......

我被困在这里......

感谢您的回复，但我没有得到这个.......
我用这个方法解析了XML

现在我希望将数据存储到结构数组中而不是简单的数组.......因为XML是动态的，并且可以增加大小（标签）所以我认为将数据存储到结构数组中（不是单独的阵列）将是更好的aproach .....

2 个答案:

答案 0 :(得分：1)

NSIS没有对数组的本机支持，但您可以使用here列出的替代方案之一。

答案 1 :(得分：1)

首先，您需要使用一些XML插件解析XML中的数据（例如：http://nsis.sourceforge.net/XML_plug-in）。

然后使用一些http://nsis.sourceforge.net/Arrays_in_NSIS插件将数据保存在数组中（建议使用nsArray插件）。

你想将整个树保存在数组中吗？我认为这是一项非常艰巨的任务，因为有很多可能性：你想保存所有元素还是只保存非空元素？ 或者你只是想读一些值？

请更具体地说明数组的外观。

编辑:(示例）

只需在循环中遍历已加载的树并保存数据：

  IntOp $R1 0 + 0 ; Set $R1 to zero at beginning

  ${While} End_Of_XML_Tree

    ; Fill $your_value with the data you want (element name, value or even whole node path)

    nsArray::Set your_array /key=$R1 $your_value ; Save value to your_array at key = $R1
    IntOp $R1 $R1 + 1 ; Increase $R1 (next key)
  ${EndWhile}

nsArray :: Set在value添加key，用该键替换任何现有值。
