c# - 如何解析这部分XML

Question

我是 XML 的新手，对解析此类文件有疑问:

XML 文档:

<?xml version="1.0" encoding="UTF-8"?>
<ISBNdb server_time="2005-07-29T02:41:22">
    <BookList total_results="1" page_size="10" page_number="1" shown_results="1">
        <BookData book_id="law_and_disorder" isbn="0210406240">
            <Title>Law and disorder</Title>
            <TitleLong>Law and disorder: law enforcement in television network news</TitleLong>
            <AuthorsText>V. M. Mishra</AuthorsText>
            <PublisherText publisher_id="asia_pub_house">New York: Asia Pub. House, c1979.</PublisherText>
            <Details    dewey_decimal="302.2/3"
                        dewey_decimal_normalized="302.23"
                        lcc_number="PN4888"
                        language="eng"
                        physical_description_text="x, 127 p. ; 22 cm."
                        edition_info=""
                        change_time="2004-10-19T23:52:56"
                        price_time="2005-07-29T02:06:41" />
        </BookData>
    </BookList>
</ISBNdb>

我将如何获得 ISBN 编号 <BookData book_id="law_and_disorder" isbn="0210406240">从文件的这一部分？下面是我用来解析的 C#:

C#解析代码

 XmlNodeList nodes = doc.DocumentElement.SelectNodes("/ISBNdb/BookList");
            List<Book> books = new List<Book>();

            foreach (XmlNode node in nodes)
            {
                Book book = new Book();

                book.author = node.SelectSingleNode("BookData/AuthorsText").InnerText;
                book.title = node.SelectSingleNode("BookData/Title").InnerText;
                book.ISBN = node.SelectSingleNode("BookData").LastChild.ToString();

                books.Add(book);

                addInfo(book.author, book.title, book.ISBN);
            }

我知道有不同的“节点”，例如“标题”和“详细信息”。但是，我不明白如何从节点“标签”本身获取信息。非常感谢任何澄清，并随时纠正我不正确的“定义”

谢谢!

Answer 1

book.ISBN = node.SelectSingleNode("BookData").Attributes["isbn"].Value;

isbn 是 BookData 的一个属性，而不是 child (即 Title)
