Aspose.word for java 请问有通过文档中的内容完成替换且同时锁定其他区域的方法吗

例如
xxxxx[]xxxxx
期望效果
1、转换成 xxxxx___xxxxx
2、xxxxx部分为锁定状态不可编辑 ， ____ 部分为可编辑状态

@chazz, 目前尚不清楚您要实现的目标。 能否请您详细说明，如果可能请提供文档或图片或示例代码？

归档.zip (18.8 KB)

请查看此压缩包，原文档期望通过代码转换为目标文档

同时将文档设置为保护模式，只允许图中区域可编辑

@chazz, 请看这个例子：

String documentName = "原文档.docx";
Document doc = new Document(documentName);

FindReplaceOptions options = new FindReplaceOptions();
options.setReplacingCallback(new FindReplaceHandler());

String stringPattern = "[]";
String replacement = "_____";
doc.getRange().replace(stringPattern, replacement, options);

doc.protect(ProtectionType.READ_ONLY);
doc.save("protected.docx");


static class FindReplaceHandler implements IReplacingCallback {
    public int replacing(ReplacingArgs e) throws Exception {
        Node currentNode = e.getMatchNode();

        // The first (and may be the only) run can contain text before the match,
        // in this case it is necessary to split the run.
        if (e.getMatchOffset() > 0)
            currentNode = SplitRun((Run) currentNode, e.getMatchOffset());

        // This array is used to store all nodes of the match for further removing.
        ArrayList runs = new ArrayList();

        // Find all runs that contain parts of the match string.
        int remainingLength = e.getMatch().group().length();
        while ((remainingLength > 0) &&
                (currentNode != null) &&
                (currentNode.getText().length() <= remainingLength))
        {
            runs.add(currentNode);
            remainingLength = remainingLength - currentNode.getText().length();

            // Select the next Run node.
            // Have to loop because there could be other nodes such as BookmarkStart etc.
            do
            {
                currentNode = currentNode.getNextSibling();
            }
            while ((currentNode != null) && (currentNode.getNodeType() != NodeType.RUN));
        }

        // Split the last run that contains the match if there is any text left.
        if ((currentNode != null) && (remainingLength > 0))
        {
            SplitRun((Run)currentNode, remainingLength);
            runs.add(currentNode);
        }

        Document doc = (Document)e.getMatchNode().getDocument();
        DocumentBuilder builder = new DocumentBuilder(doc);

        Run startRun = (Run) runs.get(0);
        builder.moveTo(startRun);

        // Insert editable text.
        builder.startEditableRange();
        builder.write(e.getReplacement());
        builder.endEditableRange();

        // Removes nodes containing the search string.
        for (Node node : (Iterable<Node>)runs)
        {
            node.remove();
        }

        return ReplaceAction.SKIP;
    }

    private static Run SplitRun(Run run, int position) {
        ((Document) run.getDocument()).stopTrackRevisions();
        Run afterRun = (Run) run.deepClone(true);
        afterRun.setText(run.getText().substring(position));
        run.setText(run.getText().substring((0), (0) + (position)));
        run.getParentNode().insertAfter(afterRun, run);

        return afterRun;
    }
}
