You can read CSV file with this tool and serialize it to XML.

blocks|key|1862386|text|我有一个用于处理CSV和平面文件的开源框架。也许它值得一看：JFileHelpers。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1862387|使用该工具包，您可以使用bean编写代码，如下所示：|1862388|@FixedLengthRecord()

I have an opensource framework for working with CSV and flat files in general. Maybe it's worth looking: <a href="http://jfilehelpers.com" rel="noreferrer" title="JFileHelpers">JFileHelpers</a>.

With that toolkit you can write code using beans, like:

<pre><code>@FixedLengthRecord()
public class Customer {
 @FieldFixedLength(4)
 public Integer custId;

 @FieldAlign(alignMode=AlignMode.Right)
 @FieldFixedLength(20)
 public String name;

 @FieldFixedLength(3)
 public Integer rating;

 @FieldTrim(trimMode=TrimMode.Right)
 @FieldFixedLength(10)
 @FieldConverter(converter = ConverterKind.Date, 
 format = "dd-MM-yyyy")
 public Date addedDate;

 @FieldFixedLength(3)
 @FieldOptional
 public String stockSimbol; 
}
</code></pre>

and then just parse your text files using:

<pre><code>FileHelperEngine&lt;Customer&gt; engine = 
 new FileHelperEngine&lt;Customer&gt;(Customer.class); 
List&lt;Customer&gt; customers = 
 new ArrayList&lt;Customer&gt;();

customers = engine.readResource(
 "/samples/customers-fixed.txt");
</code></pre>

And you'll have a collection of parsed objects.

Hope that helps!

blocks|key|1862201|text|我不明白你为什么要这么做。这听起来就像是货物狂欢节的编码。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1862202|将CSV文件转换为XML不会增加任何价值。您的程序已经在读取CSV文件，因此争论您需要XML是行不通的。|1862203|另一方面，读取CSV文件、对值执行某些操作，然后序列化到XML确实有意义(当然，就像使用XML也有意义一样……;))，但是您应该已经有了一种序列化到XML的方法。|1862204|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

I don't understand why you would want to do this. It sounds almost like cargo cult coding.

Converting a CSV file to XML doesn't add any value. Your program is already reading the CSV file, so arguing that you need XML doesn't work.

On the other hand, reading the CSV file, doing something with the values, and then serializing to XML does make sense (well, as much as using XML can make sense... ;)) but you would supposedly already have a means of serializing to XML.

blocks|key|2076219|text|最大的不同是，JSefa引入的是它可以将java对象序列化为CSV/XML/etc文件，并可以反序列化为java对象。而且它是由注释驱动的，这让你可以很好地控制输出。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2076220|JFileHelpers看起来也很有趣。|2076221|entityMap|0|LINK|mutability|MUTABLE|url|http://jsefa.sourceforge.net/index.html^0|7|5|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]]|C|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@]|C|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]]]

The big difference is that <a href="http://jsefa.sourceforge.net/index.html" rel="noreferrer">JSefa</a> brings in is that it can serialize your java objects to CSV/XML/etc files and can deserialize back to java objects. And it's driven by annotations which gives you lot of control over the output. 

JFileHelpers also looks interesting.

You can do this exceptionally easily using Groovy, and the code is very readable. 

Basically, the text variable will be written to <code>contacts.xml</code> for each line in the <code>contactData.csv</code>, and the fields array contains each column.

<pre><code>def file1 = new File('c:\\temp\\ContactData.csv')
def file2 = new File('c:\\temp\\contacts.xml')

def reader = new FileReader(file1)
def writer = new FileWriter(file2)

reader.transformLine(writer) { line -&gt;
 fields = line.split(',')

 text = """&lt;CLIENTS&gt;
 &lt;firstname&gt; ${fields[2]} &lt;/firstname&gt;
 &lt;surname&gt; ${fields[1]} &lt;/surname&gt;
 &lt;email&gt; ${fields[9]} &lt;/email&gt;
 &lt;employeenumber&gt; password &lt;/employeenumber&gt;
 &lt;title&gt; ${fields[4]} &lt;/title&gt;
 &lt;phone&gt; ${fields[3]} &lt;/phone&gt;
 &lt;/CLIENTS&gt;"""
}
</code></pre>

blocks|key|1862256|text|据我所知，没有现成的库可以为您完成这项工作，但是要生成一个能够从CSV转换为XML的工具，您应该只需要编写一个粗糙的CSV解析器，并将JDOM+(或您选择的XML+Java库)与一些胶水代码连接起来。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1862257|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

As far as I know, there's no ready-made library to do this for you, but producing a tool capable of translating from CSV to XML should only require you to write a crude CSV parser and hook up JDOM (or your XML Java library of choice) with some glue code.

blocks|key|2076180|text|Daniel+Parker还提供了一个很好的库ServingXML，它能够将几乎任何纯文本格式转换为XML语言或将其转换回来。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2076181|您的示例可以在here中找到:它使用CSV文件中字段的标题作为XML元素名称。|2076182|entityMap|0|LINK|mutability|MUTABLE|url|http://servingxml.sourceforge.net/|1|http://servingxml.sourceforge.net/examples/index.html#d62e305^0|N|A|0|0|7|4|1|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]]|C|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@$A|U|B|V|1|W]]|C|$]]|$1|F|3|-4|5|6|7|X|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|O]]]]

The example for your case can be found <a href="http://servingxml.sourceforge.net/examples/index.html#d62e305" rel="noreferrer">here</a>: It uses heading of field in CSV file as the XML element name.

Jackson processor family has backends for multiple data formats, not just JSON. This includes both XML (<a href="https://github.com/FasterXML/jackson-dataformat-xml" rel="nofollow">https://github.com/FasterXML/jackson-dataformat-xml</a>) and CSV (<a href="https://github.com/FasterXML/jackson-dataformat-csv/" rel="nofollow">https://github.com/FasterXML/jackson-dataformat-csv/</a>) backends.

Conversion would rely on reading input with CSV backend, write using XML backend. This is easiest to do if you have (or can define) a POJO for per-row (CSV) entries. This is not a strict requirement, as content from CSV may be read "untyped" as well (a sequence of <code>String</code> arrays), but requires bit more work on XML output.

For XML side, you would need a wrapper root object to contain array or <code>List</code> of objects to serialize.

I had the same problem and needed an application to convert a CSV file to a XML file for one of my projects, but didn't find anything free and good enough on the net, so I coded my own Java Swing CSVtoXML application.

If not, you can easily code your own like I did; The source code is inside the jar file so modify it as you need if it doesn't fill your requirement.

Is there an existing application or library in Java which will allow me to convert a <code>CSV</code> data file to <code>XML</code> file? 

The <code>XML</code> tags would be provided through possibly the first row containing column headings.

Java lib or app to convert CSV to XML file?

JSON

Java

在Java中是否有一个现有的应用程序或库可以让我将CSV数据文件转换为XML文件？XML标记可能通过包含列标题的第一行提供。
