DOMException: String contains an invalid character

这个错误通常发生在处理XML或HTML文档时，因为这些文档要求遵循特定的字符编码规则。如果遇到无效的字符（如非法的Unicode字符），就会抛出DOMException异常。

解决方法包括：

1. 对输入的字符串进行处理，将无效字符替换或删除。
2. 确认输入的字符串是否符合文档的字符编码规则，如果不符合，需要进行转换。
3. 检查文档是否正确声明了字符编码，如果没有声明，则需要添加声明。

你需要根据具体情况进行调试和处理。

Parses text from the beginning of the given string to produce a date. The method may not use the entire text of the given string.

If you want to parse the text from the beginning of the string to produce a date, you can use the `parse()` method of the `SimpleDateFormat` class along with the `setLenient()` method set to `false`. By default, the `setLenient()` method is set to `true`, which allows for lenient parsing of dates. When set to `false`, it requires strict parsing.

Here's an example:

import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class StringToDateExample {
    public static void main(String[] args) {
        String dateString = "2022-01-01 12:34:56";
        DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");

        try {
            dateFormat.setLenient(false);
            Date date = dateFormat.parse(dateString);
            System.out.println(date);
        } catch (ParseException e) {
            e.printStackTrace();
        }
    }
}

In the above example, we set `setLenient(false)` to enforce strict parsing. The provided date string includes a time component, but since we only specify the format as "yyyy-MM-dd", the time component will not be considered. The parsing will stop at the first encountered invalid character or when the format pattern is satisfied.

Note that if the provided string contains additional characters after the date portion, they will be ignored during parsing.

I hope this helps! Let me know if you have any further questions.
