使用 Apache POI 替换 WinWord 文档中的文本

我需要替换 WinWord 文档中的某些文本。问题是，我使用replaceText函数在Range上进行的任何文本替换都会创建一个损坏的WinWord文件，除非替换字符串和替换字符串的长度完全相同。我们将处理动态内容，所以这是行不通的。

范围对象规格： http:// poi.apache.org/apidocs/org/apache/poi/hwpf/usermodel/Range.html#replaceText(java.lang.String, java.lang.String)

ReplaceText 函数有一个可选的第三个参数， int，指定某种偏移量。我想这可能是解决方案，但参数甚至无法处理负值，这使得很难或不可能进行替换，除非偏移量 (replacement.length() -然而，我可能需要它是负数。无论如何，如果其他两个参数长度不相等，文档中似乎没有任何内容暗示需要此偏移参数

。（假设 a.doc 仅包含“caaaaaaake”）

      String inputFilename = "C:\\\a.doc"; 

      String outputFilename = "C:\\b.doc";
      POIFSFileSystem fs = null;
      FileInputStream fis = new FileInputStream(inputFilename);
      fs = new POIFSFileSystem(fis);

      HWPFDocument doc = new HWPFDocument(fs);

      Range range = doc.getRange();
      range.replaceText("caaaaaaake", "piiiie");


      FileOutputStream fos = new FileOutputStream(outputFilename);
      doc.write(fos);

      fis.close();
      fos.close();

代码执行没有问题，但它创建了一个损坏的 word 文件。我能做些什么？

原文

I need to replace certain text in a WinWord document. The problem is, any text replacement I do on a Range with the replaceText function creates a broken WinWord file unless the replacement and replaced strings are both the exact same length. We will be dealing with dynamic content, so this will not do.

Range object specs:
http://poi.apache.org/apidocs/org/apache/poi/hwpf/usermodel/Range.html#replaceText(java.lang.String, java.lang.String)

The replaceText function has an optional third parameter, an int, to specify some sort of offset. I thought maybe this could be the solution, but the param can't even handle a negative value, which makes it hard or impossible to do a replacement unless the offset (replacement.length() - replaced.length()) is positive. However, I may need it to be negative. Anyhow, nothing in the docs would seem to imply that this offset param is needed if the two other params aren't equal length.

Here's my code:
(let's say a.doc just contains "caaaaaaake")

      String inputFilename = "C:\\\a.doc"; 

      String outputFilename = "C:\\b.doc";
      POIFSFileSystem fs = null;
      FileInputStream fis = new FileInputStream(inputFilename);
      fs = new POIFSFileSystem(fis);

      HWPFDocument doc = new HWPFDocument(fs);

      Range range = doc.getRange();
      range.replaceText("caaaaaaake", "piiiie");


      FileOutputStream fos = new FileOutputStream(outputFilename);
      doc.write(fos);

      fis.close();
      fos.close();

The code executes no problem, but it creates a broken word file.
What can I do?
