Question

我从webclient收到以下字符串，我想将其转换为数组或列表或xml文档，以便我可以遍历它。我尝试转换为Linq.XDocument.Parse（strResponse）但失败并出现错误：根级别的数据无效。第1行，第1位。

转换：

String strResponse = Encoding.UTF8.GetString( response );
XDocument xmldoc = XDocument.Parse( strResponse );

上面的

strResponse看起来像：

array(3) {
    [0]=>
      array(5) {
        ["brand"]=>
        string(6) "Abarth"
        ["range"]=>
        string(3) "500"
        ["model"]=>
        string(8) "500 1.4T"
        ["mm_code"]=>
        string(8) "00815150"
        ["intro_date"]=>
        string(10) "2012-01-12"
      }
      [1]=>
      array(5) {
        ["brand"]=>
        string(6) "Abarth"
        ["range"]=>
        string(3) "500"
        ["model"]=>
        string(17) "500 1.4T esseesse"
        ["mm_code"]=>
        string(9) "008151501"
        ["intro_date"]=>
        string(10) "2012-01-12"
      }
      [2]=>
      array(5) {
        ["brand"]=>
        string(6) "Abarth"
        ["range"]=>
        string(3) "500"
        ["model"]=>
        string(9) "500C 1.4T"
        ["mm_code"]=>
        string(8) "00815180"
        ["intro_date"]=>
        string(10) "2012-01-12"
      }
  }

当我尝试将其转换为xml文档时，是否有人可能会看到上述响应为什么会抛出错误？还有更好的建议吗？

提前致谢。

Answer 1

这看起来像JSON而不是XML，您可以尝试使用JSON序列化程序

Answer 2

您的回复是PHP数组您可以使用Regex或其他逻辑来编写自己的转换器或者使用某些第三方库，例如Conversive.PHPSerializationLibrary
