xml - 如何将 xml 放入 couchDB？

Question

我想这样做: 1. PUT 一个 xml 字符串到 couchdb 服务器。像这样的东西:

curl -X PUT  http://localhost:5984/db/_design/app/_update/echo/h1
-d "<doc><name1>value1</name1><name2>value2</name2></doc>"

1. 在 couchdb 服务器端，我将 xml 字符串解析为 json 对象。
2. 将 json 对象保存为文档。

这可能吗？我该怎么办？

谢谢!

我找到了另一种方法，这里是示例:

1. 创建数据库

   curl -X PUT http://localhost:5984/bookstore

2. 创 build 计文档

   curl -X POST http://localhost:5984/bookstore/_bulk_docs -d @design.doc

design.doc 的内容在哪里:

{"docs":
  [
    {
        "_id": "_design/app",
        "updates": {
            "xml2json": "
              function (doc, req) {
                if(req.query.doc == null) {
                  return [null, \"doc is null!\\n\"];
                }
                var xmlDoc = req.query.doc.replace(/^<\?xml\s+version\s*=\s*([\"'])[^\1]+\1[^?]*\?>/, \"\");
                var html = new XML(xmlDoc);
                if(doc==null) {
                  doc = {};
                  doc._id=html.BookList.BookData.@isbn13.toString();
                  if(doc._id==null||doc._id==\"\") {
                    doc._id=html.BookList.BookData.@isbn.toString();
                  }
                }
                if (doc._id == null || doc._id == \"\") {
                  return [null, \"doc id is null!\\n\"];;
                }
                doc.title = html.BookList.BookData.Title.text();
                doc.longtitle = html.BookList.BookData.TitleLong.text();
                doc.authors = html.BookList.BookData.AuthorsText.text();
                doc.publisher = html.BookList.BookData.PublisherText.text();
                return [doc, \"ok!\\n\"];
              }"
        }
    }
  ]
}

1. 测试_update

   doc=$(cat isbndb.sample); doc="$(perl -MURI::Escape -e 'print uri_escape($ARGV[0]);' "$doc")"; curl -X PUT http://localhost:5984/bookstore/_design/app/_update/xml2json/9781935182320?doc="$doc"

isbndb.sample 的内容是:
