Question

我试图将XML转换为JSON，但我在这样做时丢失了数据。

在XML我最两件事护理：

​​

1. 的cint:variable-id="11734028"
2. 真实文本值 - American Indian or Alaska Native

当我转换使用Hash.from_xml(xml).to_json XML以JSON它似乎失去了价值标签内的信息。

的XML是这样的：

xml = '<?xml version="1.0" encoding="utf-8" standalone="no"?> 
<surveys xmlns:cint="http://www.cint.com/"> 
    <sss version="2.0" languages="x-native" xmlns:cint="http://www.cint.com/"> 
    <date>2017-06-28</date> 
    <time>17:00:35</time> 
    <survey> 
     <title>Ethnicity<text xml:lang="x-native">Ethnicity</text></title> 
     <record ident="c" cint:category-id="63608"> 
     <variable ident="451539" type="single" cint:sort-order="1" cint:hide-on="Registration" cint:country-language-question-id="2222"> 
      <name>Ethnicity - US &amp; Canada only</name> 
      <label>How would you define yourself as it relates to your ethnicity? (US and Canada only)<text xml:lang="x-native">How would you define yourself as it relates to your ethnicity?</text></label>

      <value code="3" cint:variable-id="11734030" cint:global-variable-id="2742" cint:country-language-variable-id="36690">Black or African American<text xml:lang="x-native">Black or African American                                                                     </text></value>

      <value code="5" cint:variable-id="11734032" cint:global-variable-id="2744" cint:country-language-variable-id="36692">Native Hawaiian or Pacific Islander<text xml:lang="x-native">Native Hawaiian or Pacific Islander                                                                   </text></value> 
      <value code="6" cint:variable-id="11734033" cint:global-variable-id="2745" cint:country-language-variable-id="36693">White<text xml:lang="x-native">White                                                                          </text></value> 
      <value code="98" cint:variable-id="11734034" cint:global-variable-id="2746" cint:country-language-variable-id="36694">Other<text xml:lang="x-native">Other                                                                          </text></value> 
      <value code="99" cint:variable-id="11734035" cint:global-variable-id="2747" cint:country-language-variable-id="36695">I prefer not to answer<text xml:lang="x-native">Prefer not to say                                                                       </text></value> 
      </values> 
     </variable> 
     </record> 
    </survey> 
    </sss> 
</surveys>' 

输出JSON是这样的：

"{\"surveys\":{\"xmlns:cint\":\"http://www.cint.com/\",\"sss\":{\"version\":\"2.0\",\"languages\":\"x-native\",\"xmlns:cint\":\"http://www.cint.com/\",\"date\":\"2017-06-28\",\"time\":\"17:00:35\",\"survey\":{\"title\":\"Ethnicity\",\"record\":{\"ident\":\"c\",\"cint:category_id\":\"63608\",\"variable\":{\"ident\":\"451539\",\"type\":\"single\",\"cint:sort_order\":\"1\",\"cint:hide_on\":\"Registration\",\"cint:country_language_question_id\":\"2222\",\"name\":\"Ethnicity - US \\u0026 Canada only\",\"label\":\"How would you define yourself as it relates to your ethnicity? (US and Canada only)\",\"position\":{\"start\":\"1\"},\"values\":{\"value\":[\"American Indian or Alaska Native\",\"Asian\",\"Black or African American\",\"Hispanic or Latino\",\"Native Hawaiian or Pacific Islander\",\"White\",\"Other\",\"I prefer not to answer\"]}}}}}}}" 

任何想法如何，我可以将此转换为JSON没有价值标签内丢失的信息？

Answer 1

the documentation中有关于Hash.from_xml无法正确解析属性的说明。

使用真正的XML解析器（如Nokogiri）可能会带来更好的运气。
