我正在寻求一些帮助，尝试将从亚马逊产品 API 检索到的 XML 转换为 CSV(逗号分隔值)格式。
我在这里找到了一个类似的主题:XML to CSV conversion issue但它使用 PHP，我想改用 javascript。
这是我所拥有的示例:

我正在尝试使用 Javascript 将此数据格式化为 CSV 格式的表格。
有人可以帮忙吗？
提前致谢! 普拉尼
最佳答案
经过长时间的调查，我发现了一些可能对您有所帮助的东西。
从重新发明轮子是如此愚蠢和耗时的任务开始，我一直在寻找其他优秀程序员已经在互联网上构建的东西。
不幸的是，我无法找到一个从 XML 到 CSV 的直接转换器，作为您在 PHP 中提供的示例。
在我的工作示例中，XML 必须像这样首先从 JSON 传递:
我在这里和那里取了一些片段，我将在这个答案的末尾添加我实际获取用于构建演示的所有代码片段的引用。通过这种方式，您将能够获得一份漂亮而干净的文档，帮助您改进此工具。
这里是一个简单的演示:
function xmlTocsv() {
var data = $("#xmlArea").val();
var xml = "";
if (data !== null && data.trim().length !== 0) {
try {
xml = $.parseXML(data);
} catch (e) {
throw e;
}
var x2js = new X2JS();
data = x2js.xml2json(xml);
jsonTocsvbyjson(data);
}
}
function jsonTocsvbyjson(data, returnFlag) {
arr = [];
flag = true;
var header = "";
var content = "";
var headFlag = true;
try {
var type1 = typeof data;
if (type1 != "object") {
data = processJSON($.parseJSON(data));
} else {
data = processJSON(data);
}
} catch (e) {
if (returnFlag === undefined || !returnFlag) {
console.error("Error in Convert to CSV");
} else {
console.error("Error in Convert :" + e);
}
return false;
}
$.each(data, function(k, value) {
if (k % 2 === 0) {
if (headFlag) {
if (value != "end") {
header += value + ",";
} else {
// remove last colon from string
header = header.substring(0, header.length - 1);
headFlag = false;
}
}
} else {
if (value != "end") {
var temp = data[k - 1];
if (header.search(temp) != -1) {
content += value + ",";
}
} else {
// remove last colon from string
content = content.substring(0, content.length - 1);
content += "\n";
}
}
});
if (returnFlag === undefined || !returnFlag) {
$("#csvArea").val(header + "\n" + content);
} else {
return (header + "\n" + content);
}
}
function processJSON(data) {
$.each(data, function(k, data1) {
var type1 = typeof data1;
if (type1 == "object") {
flag = false;
processJSON(data1);
arr.push("end");
arr.push("end");
} else {
arr.push(k, data1);
}
});
return arr;

我有一个Ruby程序，它使用rubyzip压缩XML文件的目录树。gem。我的问题是文件开始变得很重，我想提高压缩级别，因为压缩时间不是问题。我在rubyzipdocumentation中找不到一种为创建的ZIP文件指定压缩级别的方法。有人知道如何更改此设置吗？是否有另一个允许指定压缩级别的Ruby库？ 最佳答案 这是我通过查看rubyzip内部创建的代码。level=Zlib::BEST_COMPRESSIONZip::ZipOutputStream.open(zip_file)do|zip|Dir.glob("**/*")d

很好奇，就使用rubyonrails自动化单元测试而言，你们正在做什么？您是否创建了一个脚本来在cron中运行rake作业并将结果邮寄给您？git中的预提交Hook？只是手动调用？我完全理解测试，但想知道在错误发生之前捕获错误的最佳实践是什么。让我们理所当然地认为测试本身是完美无缺的，并且可以正常工作。下一步是什么以确保他们在正确的时间将可能有害的结果传达给您？ 最佳答案 不确定您到底想听什么，但是有几个级别的自动代码库控制:在处理某项功能时，您可以使用类似autotest的内容获得关于哪些有效，哪些无效的即时反馈。要确保您的提
假设我做了一个模块如下:m=Module.newdoclassCendend三个问题:除了对m的引用之外，还有什么方法可以访问C和m中的其他内容？我可以在创建匿名模块后为其命名吗(就像我输入“module...”一样)？如何在使用完匿名模块后将其删除，使其定义的常量不再存在？ 最佳答案 三个答案:是的，使用ObjectSpace.此代码使c引用你的类(class)C不引用m:c=nilObjectSpace.each_object{|obj|c=objif(Class===objandobj.name=~/::C$/)}当然这取决于
我的目标是转换表单输入，例如“100兆字节”或“1GB”，并将其转换为我可以存储在数据库中的文件大小(以千字节为单位)。目前，我有这个:defquota_convert@regex=/([0-9]+)(.*)s/@sizes=%w{kilobytemegabytegigabyte}m=self.quota.match(@regex)if@sizes.include?m[2]eval("self.quota=#{m[1]}.#{m[2]}")endend这有效，但前提是输入是倍数(“gigabytes”，而不是“gigabyte”)并且由于使用了eval看起来疯狂不安全。所以，功能正常，
我正在尝试使用ruby和Savon来使用网络服务。测试服务为http://www.webservicex.net/WS/WSDetails.aspx?WSID=9&CATID=2require'rubygems'require'savon'client=Savon::Client.new"http://www.webservicex.net/stockquote.asmx?WSDL"client.get_quotedo|soap|soap.body={:symbol=>"AAPL"}end返回SOAP异常。检查soap信封，在我看来soap请求没有正确的命名空间。任何人都可以建议我
关闭。这个问题是opinion-based.它目前不接受答案。想要改进这个问题？更新问题，以便editingthispost可以用事实和引用来回答它.关闭4年前。Improvethisquestion我想在固定时间创建一系列低音和高音调的哔哔声。例如:在150毫秒时发出高音调的蜂鸣声在151毫秒时发出低音调的蜂鸣声200毫秒时发出低音调的蜂鸣声250毫秒的高音调蜂鸣声有没有办法在Ruby或Python中做到这一点？我真的不在乎输出编码是什么(.wav、.mp3、.ogg等等)，但我确实想创建一个输出文件。
我在我的项目目录中完成了compasscreate.和compassinitrails。几个问题:我已将我的.sass文件放在public/stylesheets中。这是放置它们的正确位置吗？当我运行compasswatch时，它不会自动编译这些.sass文件。我必须手动指定文件:compasswatchpublic/stylesheets/myfile.sass等。如何让它自动运行？文件ie.css、print.css和screen.css已放在stylesheets/compiled。如何在编译后不让它们重新出现的情况下删除它们？我自己编译的.sass文件编译成compiled/t
我想将html转换为纯文本。不过，我不想只删除标签，我想智能地保留尽可能多的格式。为插入换行符标签，检测段落并格式化它们等。输入非常简单，通常是格式良好的html(不是整个文档，只是一堆内容，通常没有anchor或图像)。我可以将几个正则表达式放在一起，让我达到80%，但我认为可能有一些现有的解决方案更智能。 最佳答案 首先，不要尝试为此使用正则表达式。很有可能你会想出一个脆弱/脆弱的解决方案，它会随着HTML的变化而崩溃，或者很难管理和维护。您可以使用Nokogiri快速解析HTML并提取文本:require'nokogiri'h
