值 "name" 和 "surname" 未读取 apache poi
The value "name" and "surname" aren't read apache poi
我的目的是读取文件 docx 并获取此文本“#name#”和“#surname#”并将值更改为另一个随意文本：
这是我的 docx 文件：
我这样做：
XWPFDocument docx = new XWPFDocument(OPCPackage.open("..."));
for (XWPFParagraph p : docx.getParagraphs()) {
List<XWPFRun> runs = p.getRuns();
if (runs != null) {
for (XWPFRun r : runs) {
String text = r.getText(0);
if (text != null && text.startsWith("#") && text.endsWith("#")) {
text = text.replace("#", "new ");
r.setText(text, 0);
}
}
}
}
for (XWPFTable tbl : docx.getTables()) {
for (XWPFTableRow row : tbl.getRows()) {
for (XWPFTableCell cell : row.getTableCells()) {
for (XWPFParagraph p : cell.getParagraphs()) {
for (XWPFRun r : p.getRuns()) {
String text = r.getText(0);
if (text != null && text.startsWith("#") && text.endsWith("#")) {
text = text.replace("#", "new ");
r.setText(text,0);
}
}
}
}
}
问题是我的代码读取了 docx 文件中的所有标签，但没有读取标签“#surname#”和“#name”。谁能帮帮我？
从你的屏幕截图来看，“#name#”和“#surmane#”似乎不直接在文档正文中，而是在绘图中（例如文本框或形状）。 XWPFDocument.getParagraphs 或 .getTables 或 apache poi 中的任何其他高级方法均未涵盖此类元素。所以你的主要问题是你的代码根本没有遍历包含你的文本的段落。
从文档正文中真正获取所有段落的唯一方法是使用 XmlCursor 直接从 XML 中选择所有 w:p 元素。
下面的代码显示了这一点。它使用 XmlCursor 遍历文档正文中的所有 XWPFParagraphs 并在找到时替换文本。
对于替换过程，我更喜欢 中显示的 TextSegment 替换方法。这是必要的，因为即使包含的段落被遍历，由于格式、拼写检查或任何其他奇怪的原因，文本可能会在不同的文本运行中分开。 Microsoft Word 知道将文本奇怪地分成不同文本行的近乎无限的理由。
