  1. POText replacement in WinWord doc using Apache POI
    text
    copied!<p>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.</p> <p>Range object specs: <a href="http://poi.apache.org/apidocs/org/apache/poi/hwpf/usermodel/Range.html#replaceText(java.lang.String" rel="nofollow noreferrer">http://poi.apache.org/apidocs/org/apache/poi/hwpf/usermodel/Range.html#replaceText(java.lang.String</a>, java.lang.String)</p> <p>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.</p> <p>Here's my code: (let's say a.doc just contains "caaaaaaake")</p> <pre><code> 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(); </code></pre> <p>The code executes no problem, but it creates a broken word file. What can I do?</p>
