java填充wordxml格式,java xml转成word文档格式

要填充 Word XML 格式，你可以使用 Java 中的 Apache POI 库。下面给出一个简单的示例代码：

import java.io.File;
import java.io.FileOutputStream;

import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.xmlbeans.XmlCursor;
import org.apache.xmlbeans.XmlObject;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTAltChunk;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTP;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTTbl;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTTblPr;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTTblWidth;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.STTblWidth;

public class WordXMLFiller {

    public static void main(String[] args) throws Exception {
        // Load the Word XML template
        XWPFDocument doc = new XWPFDocument(new File("template.xml"));

        // Find the placeholder text you want to replace
        String placeholder = "Hello, {name}!";
        XWPFParagraph paragraph = findParagraph(doc, placeholder);

        // Replace the placeholder text with your own text
        String name = "John Doe";
        replaceText(paragraph, placeholder, name);

        // Save the filled-in Word XML document to disk
        FileOutputStream out = new FileOutputStream("output.xml");
        doc.write(out);
        out.close();
        doc.close();
    }

    private static XWPFParagraph findParagraph(XWPFDocument doc, String text) {
        for (XWPFParagraph paragraph : doc.getParagraphs()) {
            if (paragraph.getText().contains(text)) {
                return paragraph;
            }
        }
        return null;
    }

    private static void replaceText(XWPFParagraph paragraph, String oldText, String newText) {
        String text = paragraph.getText();
        int start = text.indexOf(oldText);
        int end = start + oldText.length();
        if (start != -1) {
            XmlCursor cursor = paragraph.getCTP().newCursor();
            cursor.toStartToken();
            cursor.toNextSibling();
            XmlObject object = cursor.getObject();
            if (object instanceof CTP) {
                CTP ctp = (CTP) object;
                ctp.setTArray(0, ctp.getTArray(0).replaceFirst(oldText, newText));
            } else if (object instanceof CTTbl) {
                CTTbl tbl = (CTTbl) object;
                CTTblPr tblPr = tbl.getTblPr();
                if (tblPr == null) {
                    tblPr = tbl.addNewTblPr();
                }
                CTTblWidth tblWidth = tblPr.getTblW();
                if (tblWidth == null) {
                    tblWidth = tblPr.addNewTblW();
                    tblWidth.setType(STTblWidth.AUTO);
                }
                CTAltChunk altChunk = tbl.addNewAltChunk();
                altChunk.setRid("rId1");
            }
        }
    }
}

此外，如果你想将 XML 转换为 Word 文档格式，可以使用 Apache POI 中的 `XWPFDocument` 类来创建一个新的文档，并使用 `XWPFParagraph` 类创建段落，使用 `XWPFRun` 类创建文本运行。以下是一个示例代码：

import java.io.File;
import java.io.FileOutputStream;

import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;

public class XMLToWordConverter {

    public static void main(String[] args) throws Exception {
        // Load the XML data
        String xml = "<root><text>Hello, world!</text></root>";

        // Create a new Word document
        XWPFDocument doc = new XWPFDocument();

        // Create a new paragraph
        XWPFParagraph paragraph = doc.createParagraph();

        // Create a new run with the text from the XML
        XWPFRun run = paragraph.createRun();
        run.setText(getTextFromXML(xml));

        // Save the Word document to disk
        FileOutputStream out = new FileOutputStream("output.docx");
        doc.write(out);
        out.close();
        doc.close();
    }

    private static String getTextFromXML(String xml) throws Exception {
        // Parse the XML document and extract the text
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = factory.newDocumentBuilder();
        Document doc = builder.parse(new InputSource(new StringReader(xml)));
        XPath xpath = XPathFactory.newInstance().newXPath();
        return (String) xpath.evaluate("/root/text", doc, XPathConstants.STRING);
    }
}
