Question

我有以下特性:一毫升一米的读物。如果我打印出读物,则通常以重心印制。

reader = XML::Reader.new(File.open("somefile.xml", "r"))
reader.read
reader.read
...
p reader.node

=> ... Full_Name="Univisión Network - East Feed" ...

但是,如果我这样做,那就逃了。

p reader.node["Full_Name"]
=> "UnivisixC3xB3n Network - East Feed"

当我试图将这一价值转换为json laater时,我有以下错误。

Encoding::UndefinedConversionError: "xC3" from ASCII-8BIT to UTF-8

本文件的xml行文如下:

<?xml version="1.0" encoding="ISO-8859-1"?>

我没有控制Xml文件本身。我怎么能将这种单条编码特性重新归为 j子,或改成一种格式 j子?

Full_Name="Univisi&#243;n Network - East Feed"

Answer 1

EDIT
so i ve been trying figuring this out for quite some time now. funny thing: your code works without error in ruby 1.8 (at least here). so i think the error has to do with ruby 1.9 s new encoding handling. somehow it cannot figure out that the parsed and read XML is in (libxml s internal) utf-8 format (the document encoding doesn t matter here: in 1.8 it works with both iso-8859-1 and utf-8, even with the wrong xml encoding declaration). instead, it treats it as ASCII-8BIT, or BINARY. in other words, it doesn t know the encoding. which is why to_json fails trying to convert it to utf-8.

解决该问题最容易的方法可能是将1.8瓦.降为1.8瓦.。

alternatively, your approach of force_encoding( UTF-8 ) seems to be reasonable.

您可以尝试将适当的编码传递给读者:

reader = XML::Reader.new(File.open("somefile.xml", "r"), 
  XML::Encoding::ISO_8859_1)

因此,我仍然完全丧失了为什么我可以推测出“权利”的方式去做,但帮助找到了“在Sting阶级采用的方法。由于我的代码涉及将属性复制成斜体,因此,它并不大要打<条码>force_encoding<>/code>。当我复制价值时。

我加倍地确保我作为“UTF-8”拯救了档案,并将正确的Xml声明摆在首位。它仍然失败。

无论如何,在我能够说明如何解决实际问题之前,该法典确定了这一问题。

  object = { type: node.name }      
  node.attributes.each do |attribute|
    name = attribute.name.gsub /_/,""
    value = attribute.value.force_encoding( UTF-8 )

    object[name] = value
  end

请注意,如果我已经不需要将 no子复制成 has,那是不适当的,因为它肯定不值得所有麻烦。如果是,

object.to_json

它没有问题。感谢你们的帮助! 你们是否有什么想法,我怎么能够强迫 x在xml上?

Answer 3

但是,如果这样做的话,就逃了。

情况并非如此。你所看到的是UTF-8的产出,它被解释为一种 by。

问题是,你的XML文件says,其编号为ISO-8859-1,而实际上是UTF-8。找出问题,应该发挥作用。
