Question

我正在尝试将一个简单的XML文件转换为CSV文件，当使用显示输出的在线工具时，该部分效果很好。

当我使用基于Java的集成软件通过代码运行文件时，会引发错误；原因：org.xml.sax.SAXParseException：文件的结尾过早。

下面，我包括了输入XML，XSLT和输出（我确定这里不需要显示输出）

我使用XML到CSV的示例作为参考，输出效果很好，我删除了一些不必要的元素/标签，这些元素/标签并没有改变期望的结果

输入：

<?xml version="1.0" encoding="UTF-8"?>
<Results>
   <Row>
      <soldto>000999900</soldto>
      <namelong>long name of company</namelong>
      <postcode>po3stc0d3</postcode>
      <AltVendDesc>some company name</AltVendDesc>
      <prodcode>09060170</prodcode>
      <proddescription>productdescriptionhere</proddescription>
      <billingdoc>0099999990</billingdoc>
      <bdate>20190905</bdate>
      <invqty>12</invqty>
      <CustPrice>7.3700</CustPrice>
      <Gross_inc.batchcharge_>88.4400</Gross_inc.batchcharge_>
      <VenProdCode>AA1234</VenProdCode>
  </Row>
</Results>

代码：

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0"  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
        <?xml-stylesheet type="text/xsl"?>

正如我之前所说，这很好，但是当通过使用Java的集成工具时，出现异常错误。

不幸的是，输入文件无法更改。

更新：尝试发布我的代码时，引号是错误，已更新。

已添加堆栈跟踪

Answer 1

修复了此问题：问题是使用者没有获取文件，因此它实际上什么也没做，而是尝试对其进行转换。

引起原因：org.xml.sax.SAXParseException：文件过早结束
