使用Aspose.Words将样式从模板复制到许多文档

Question

I am trying to create a Java “script” such that, given a template and a target document:

• reads all styles defined in the template, both for text and tables
• copies each style onto the target document, replacing the style if it already exists

To summarize, this is what I have come up until now, also based on the API reference for the StyleCollection class :

Document target = new Document(targetPath);
StyleCollection targetStyles = target.getStyles();

for (Style style : source.getStyles()) {
    switch (style.getType()) {
        case StyleType.PARAGRAPH:
        case StyleType.TABLE:
        case StyleType.LIST:
            if (!style.getName().trim().toLowerCase().endsWith("carattere")) {
                String name = style.getName();
                Style copied = styles.addCopy(style);

                switch (style.getType()) {
                    case StyleType.PARAGRAPH:
                        copied.setNextParagraphStyleName(style.getNextParagraphStyleName());
                        // fallthrough

                    case StyleType.CHARACTER:
                    case StyleType.TABLE:
                        copied.setBaseStyleName(style.getBaseStyleName());
                        break;

                    default:
                        break;
                }

                copied.setName(name);
            }
            break;

        default:
            break;
    }
}

target.save(savePath);

As of now, the problems I have identified are the following:

• if I tried using the standard MS Word styles (“Normal”, “Title 1”, …), when they're copied over they get duplicated even using the setName() “trick”
• if I instead use custom style, I have a problem with table styles, in which the text color changes

How do I get a clean copy of all the styles in the document?

if I tried using the standard MS Word styles (“Normal”, “Title 1”, …), when they're copied over they get duplicated even using the setName() “trick”

Please use following sample code snippet, it will help you to get output without style duplication.

Document source = new Document(MyDir + "template.doc");
Document target = new Document(MyDir + "target.doc");

StyleCollection sourceStyles = source.getStyles();
StyleCollection targetStyles = target.getStyles();

System.out.println("SORGENTE = " + sourceStyles.getCount() + " stili");
System.out.println("DESTINAZIONE = " + targetStyles.getCount() + " stili");

for (Style style : sourceStyles) {
    String name = style.getName();
    if (name.endsWith("Carattere")) continue;

    if (style.getType() == StyleType.PARAGRAPH
                            || style.getType() == StyleType.TABLE)
    {
        Style copied = targetStyles.addCopy(style);
        copied.setBaseStyleName(style.getBaseStyleName());

        if (style.getType() == StyleType.PARAGRAPH) {
           copied.setNextParagraphStyleName(style.getNextParagraphStyleName());
        }
        copied.setName(name);
        System.out.println("COPIA STILE " + name + " -> " + copied.getName());
    }
}

target.cleanup();
target.save(MyDir + "output.docx");

if I instead use custom style, I have a problem with table styles, in which the text color changes

Please note Aspose.Words mimics MS Word behavior. If you import the styles from your template to target document using MS Word , it will show same results as Aspose.Words does.
