I am using Docx4J to modify docx templates and put values in place of placeholders in the template that are predefined.

so far, i had been successful in finding and replacing paragraphs and texts, tables, images etc. But i am not yet successful in finding Header and/or Footer elements of the document.

I am using 

WordprocessingMLPackage wordMLPackage =
WordprocessingMLPackage.load(new java.io.File(inputfilepath));
wordMLPackage.getMainDocumentPart();

to search for elements in the template.

对于您的应用程序，您可以在第 145 行模仿https://github.com/plutext/docx4j/blob/master/src/main/java/org/docx4j/model/datastorage/BindingHandler.java中的代码

https://github.com/plutext/docx4j/blob/master/src/main/java/org/docx4j/model/fields/merge/MailMerger.java在第 124 行采用了类似的方法

这就是我设法替换页脚上的键持有者的方法（在 Java 中，没有 XML）。我缺少的是：

JaxbXmlPart part = (JaxbXmlPart) relationshipPart.getPart(r);

来自JasonPlutext提到的源代码MailMerger.java，在第 410 行中说明。所以谢谢JasonPlutext！

public static void replaceElementFromFooter(WordprocessingMLPackage template, String nameplace, String placeholder, String newValue) throws Docx4JException {
    List<Object> result = new ArrayList<Object>();

    RelationshipsPart relationshipPart = template.getMainDocumentPart().getRelationshipsPart();

    List<Relationship> relationships = relationshipPart.getRelationships().getRelationship()

    for (Relationship r : relationships) {

        if (r.getType().equals(nameplace)) {

            JaxbXmlPart part = (JaxbXmlPart) relationshipPart.getPart(r);

            List<Object> texts = getAllElementsFromObject(part.getContents(), Text.class);

            replaceTextElement(texts, placeholder, newValue);
        }

    }

    return result;
}

private static List<Object> getAllElementsFromObject(Object obj, Class<?> toSearch) {
    List<Object> result = new ArrayList<Object>();

    if (obj instanceof JAXBElement) {
        obj = ((JAXBElement<?>) obj).getValue();
    }

    if (obj.getClass().equals(toSearch)) {
        result.add(obj);
    } else if (obj instanceof ContentAccessor) {
        List<?> children = ((ContentAccessor) obj).getContent();
        for (Object child : children) {
            result.addAll(getAllElementFromObject(child, toSearch));
        }
    }
    return result;
}

private static void replaceTextElement(List<Object> texts, String placeholder, String newValue) {
    for (Object element : texts) {
        Text textElement = (Text) element;

        if (textElement.getValue().contains(placeholder)) {
            String replacedValue = textElement.getValue().replaceAll(placeholder, newValue);
            textElement.setValue(replacedValue);
        }

    }
}

如果您在 XML 中搜索和替换，您可以使用：

String xpath = "//w:r[w:t[contains(text(), 'placeholder')]]";
List<Object> list = wordMLPackage.getHeaderFooterPolicy().getDefaultHeader().getJAXBNodesViaXPath(xpath, false);
list.addAll(wordMLPackage.getHeaderFooterPolicy().getDefaultFooter().getJAXBNodesViaXPath(xpath, false));

该列表包含占位符所在的所有节点。之后就可以用我这里解释的方法获取占位符的类型（文字、图片...）（适用于文字但很容易适应）： replace_placeholder
