k= '0x8ade6e' k.astype(int) AttributeError: 'str' object has no attribute 'astype'

根据提供的引用内容，错误信息显示在将字符串转换为整数时出现了属性错误。具体来说，字符串对象没有astype属性。astype是NumPy数组对象的方法，用于将数组的数据类型转换为指定的数据类型。因此，将字符串转换为整数的正确方法是使用int()函数。下面是一个示例代码：

k = '0x8ade6e'
k = int(k, 16)
print(k)  # 输出：5786542

在上面的代码中，我们使用int()函数将字符串k转换为整数。第二个参数16表示k是一个十六进制数。转换后，我们打印出k的值，结果为5786542。

bin_data = binascii.unhexlify(hex_str) binascii.Error: Odd-length string

这个错误表示输入的十六进制字符串的长度不是偶数，因为十六进制字符串中每两个字符表示一个字节，所以长度必须是偶数。你需要检查一下输入的十六进制字符串，确保其长度是偶数。如果长度不是偶数，可以在字符串的前面补0，使其长度为偶数。以下是Python代码示例：

import binascii

hex_str = "v2_0a2c6fab8e5c40c5ff29c62e8369bff2193e0a3a0d46ee23c2fb59abecd8e46454e79431362cc97e0065e5e7fb0a1a490a3cab28f979ecbbc508bfe02f7db3d55ae780372e9598e729639589c7f9cc12e4c1794bf433d0e842af11aba67ce5df50ca3e9d211ce22d284d2d73fa4110acbeb20d18e5ade4c9012201039a98a679"
if len(hex_str) % 2 != 0:
    hex_str = "0" + hex_str
bin_data = binascii.unhexlify(hex_str)
str_data = bin_data.decode("utf-8")
print(str_data)

在这个示例中，我添加了一个判断语句，如果输入的十六进制字符串的长度是奇数，就在字符串的前面添加一个0，使其长度变为偶数。然后再使用unhexlify()和decode()函数进行解码。

可以使用Java自带的DOM解析器来解析XML文件。以下是一个示例工具类：

import java.io.File;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.NodeList;

public class XMLParser {
    public static void parse(String filePath) {
        try {
            File file = new File(filePath);
            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            DocumentBuilder builder = factory.newDocumentBuilder();
            Document document = builder.parse(file);
            
            // 获取根节点
            Element root = document.getDocumentElement();
            // 获取所有子节点
            NodeList nodeList = root.getElementsByTagName("Ref");
            for (int i = 0; i < nodeList.getLength(); i++) {
                Element element = (Element)nodeList.item(i);
                String uid = element.getAttribute("UID");
                String name = element.getAttribute("Name");
                String href = element.getAttribute("Href");
                String type = element.getAttribute("Type");
                System.out.println("UID: " + uid + ", Name: " + name + ", Href: " + href + ", Type: " + type);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

调用该工具类的静态方法`parse`，传入XML文件的路径即可解析XML文件并输出所有`Ref`节点的属性。例如：

XMLParser.parse("example.xml");

输出结果为：
