Question

我正在尝试将书签替换为值。

peer channel join block_name.block

我能够将书签替换为值，但它与书签文本的格式（字体系列，字体大小，颜色等）不一样。

任何人都可以提供一些建议。

如前所述，我相信这是您的确切用例，官方存档链接 help请着重使用 Node styleNode 复制样式信息。

    /**
     * Replace the text - if any - contained between the bookmarkStart and
it's
     * matching bookmarkEnd tag with the text specified. The technique used
will
     * resemble that employed when inserting text after the bookmark. In
short,
     * the code will iterate along the nodes until it encounters a matching
     * bookmarkEnd tag. Each node encountered will be deleted unless it is
the
     * final node before the bookmarkEnd tag is encountered and it is a
     * character run. If this is the case, then it can simply be updated to
     * contain the text the users wishes to see inserted into the document.
If
     * the last node is not a character run, then it will be deleted, a new
run
     * will be created and inserted into the paragraph between the
bookmarkStart
     * and bookmarkEnd tags.
     *
     * @param run An instance of the XWPFRun class that encapsulates the
text
     * that is to be inserted into the document following the bookmark.
