如何将 docx 文件表格单元格中的完整文本获取为单个字符串

我正在尝试使用 docx4j api 获取 java 代码中的 docx 文件表数据。在这里，我试图一次获取每个单元格数据。如何获取该数据。这里我放置具有递归方法调用的代码。

static void walkList1(List children) {
    i=children.size();
    int i=1;
    for (Object o : children) {
        if (o instanceof javax.xml.bind.JAXBElement) {
            if (((JAXBElement) o).getDeclaredType().getName()
                    .equals("org.docx4j.wml.Text")) {
                org.docx4j.wml.Text t = (org.docx4j.wml.Text) ((JAXBElement) o)
                .getValue();
                System.out.println(" 1 1    " + t.getValue());
            }
        }
        else if (o instanceof org.docx4j.wml.R) {
            org.docx4j.wml.R run = (org.docx4j.wml.R) o;
            walkList1(run.getRunContent());
        } else {
            System.out.println(" IGNORED " + o.getClass().getName());
        }
    }
}

I am trying to get the docx file table data in java code using docx4j api.
Here i am trying to get the each cell data at a time .how to get that data..here i am placing my code which have recursive method calls.

static void walkList1(List children) {
    i=children.size();
    int i=1;
    for (Object o : children) {
        if (o instanceof javax.xml.bind.JAXBElement) {
            if (((JAXBElement) o).getDeclaredType().getName()
                    .equals("org.docx4j.wml.Text")) {
                org.docx4j.wml.Text t = (org.docx4j.wml.Text) ((JAXBElement) o)
                .getValue();
                System.out.println(" 1 1    " + t.getValue());
            }
        }
        else if (o instanceof org.docx4j.wml.R) {
            org.docx4j.wml.R run = (org.docx4j.wml.R) o;
            walkList1(run.getRunContent());
        } else {
            System.out.println(" IGNORED " + o.getClass().getName());
        }
    }
}

这部分看起来很可疑：

i=children.size();
int i=1;

第一个必须是可变的静态字段（因为否则你的代码将无法编译），这通常是一个坏主意。第二个是该方法的本地函数，但从未使用过。

如果您尝试将所有内容合并到一个 String 中，我建议您创建一个 StringBuilder 并将其传递给递归调用，例如：

static String walkList(List children) {
    StringBuilder dst = new StringBuilder();
    walkList1(children, dst);
    return dst.toString();
}
static void walkList1(List children, StringBuilder dst) {
    for (Object o : children) {
        if (o instanceof javax.xml.bind.JAXBElement) {
            if (((JAXBElement) o).getDeclaredType().getName()
                    .equals("org.docx4j.wml.Text")) {
                org.docx4j.wml.Text t = (org.docx4j.wml.Text) ((JAXBElement) o)
                .getValue();
                dst.append(t);
            }
        }
        else if (o instanceof org.docx4j.wml.R) {
            org.docx4j.wml.R run = (org.docx4j.wml.R) o;
            walkList1(run.getRunContent(), dst);
        } else {
            System.out.println(" IGNORED " + o.getClass().getName());
        }
    }
}

Also List; 和 JAXBElement 是泛型类型。有什么理由使用原始类型吗？

This part looks suspicious:

i=children.size();
int i=1;

The first must be a mutable static field (because otherwise your code will not compile) which is usually a bad idea. The second is local to the method but is never used.

If you are trying to combine all content into a single String I suggest you create a StringBuilder and pass that to your recursive calls, e.g.:

static String walkList(List children) {
    StringBuilder dst = new StringBuilder();
    walkList1(children, dst);
    return dst.toString();
}
static void walkList1(List children, StringBuilder dst) {
    for (Object o : children) {
        if (o instanceof javax.xml.bind.JAXBElement) {
            if (((JAXBElement) o).getDeclaredType().getName()
                    .equals("org.docx4j.wml.Text")) {
                org.docx4j.wml.Text t = (org.docx4j.wml.Text) ((JAXBElement) o)
                .getValue();
                dst.append(t);
            }
        }
        else if (o instanceof org.docx4j.wml.R) {
            org.docx4j.wml.R run = (org.docx4j.wml.R) o;
            walkList1(run.getRunContent(), dst);
        } else {
            System.out.println(" IGNORED " + o.getClass().getName());
        }
    }
}

Also List<T> and JAXBElement<T> are generic types. Is there any reason to use the raw types?
