问题标签 [xml2js]

使用 xml2js nodejs 模块，我设法使用以下代码从（大！）xml文档中提取；

这个“有效”，结果的一小部分摘录如下；

但我现在想做的是从中提取一些信息。

特别是，我想知道列表中出现了多少次，例如“vehicle_id”的条目。

然后我可以将它用于我测试的其他部分。

任何帮助将不胜感激。

谢谢

我在解析 XML 文件时遇到问题。我想删除带有 \t\n 等字符的字符串。

XML 文件： http: //ftp.thinkimmo.com/home/immoanzeigen24/immo.xml

清洁值：

我试着用我在网上找到的很多正则表达式来清理它——但值总是如下所示：

我在向对象添加键时遇到了一些麻烦，如下所示：

以下是 console.logs 的结果 ：

我担心这个问题与异步调用有关，但我对为什么第一个console.log()工作正常感到困惑。如果是异步问题，我该如何解决？

我试图弄清楚如何将属性添加到数组元素

Error: Invalid character in name尝试从对象构建以下 XML 时出现错误。

这是我的对象

我也试过用引号括起来的名字

完全剥离属性声明会产生所需的 XML，但显然会遗漏所需的属性

我正在尝试使用 XML2JS 循环遍历 nuxt 中的 API，然后循环遍历数据以在 html 文件中显示它。

它在控制台记录时工作，但它没有在 HTML 中循环。它没有任何错误，只是空白，没有在 html 中显示任何内容。

JSON：

任何帮助将不胜感激，如果您需要我提供更多信息，请告诉我。

谢谢。

当 xml 元素被捆绑时，一些顺序会丢失。

例如，我正在阅读的 xml 具有如下元素：

可以有任意数量的<w> something </w>条目和 0 个或多个<k>something</k>条目以及 0 个或多个<q> something </q>条目。

但我需要保持解析中的顺序。当我使用以下代码时：

我得到：

我想要的是

ETC

有什么方法可以维护这些信息的顺序吗？

我正在通过 API 解析一些数据，我的解析代码如下所示，

这是我的解析器代码，但我仍然收到控制台错误
core.js:4197 ERROR Error: Uncaught (in promise): TypeError: Cannot read property 'Parser' of undefined TypeError: Cannot read property 'Parser' of undefined

所以我的问题是代码有什么问题？当我返回一个承诺时，我还能做什么？我正在返回一个新的承诺，然后我调用了解析器，那么我怎么会出错呢？谁能帮我？

我正在尝试使用 xml2js 库解析 XLIFF 文件。一切正常，但如果我有类似的东西：<source>Welcome to <x id="INTERPOLATION" equiv-text="{{ title }}"/> my friend</source>我会得到[{"_":"Welcome to my friend","x":[{"$":{"id":"INTERPOLATION","equiv-text":"{{ title }}"}}]}]. 我基本上失去了句子部分的顺序。我希望得到一个由 3 个部分组成的数组：

但相反，我得到：

如果我再次尝试重新创建字符串，我会得到<source>Welcome to my friend<x id="INTERPOLATION" equiv-text="{{ title }}"/></source>

知道如何用这个 XML 解析器或其他任何方法来解决它吗？

我正在尝试通过使用输入浏览本地机器来读取 XML 文件。

这是我的代码

在这里，我使用的确切路径仍然无法读取文件并出现此错误。

类型错误：fs__WEBPACK_IMPORTED_MODULE_3__.readFile 不是函数

我有一个返回 XML 响应的服务。我正在使用 xml2JS 将 XML 解析为 JSON。XML 看起来像 -

解析 JSON 后看起来像 -

键“children”可以有一条记录或多条记录。当键“children”有一个记录时，解析器将类型作为对象，当有多个记录时，它变成一个数组，据我所知，这是 xml2JS 解析器的工作方式。根据我的要求，我希望这个键是一个数组，不管它有多少记录。此外，这是一个数组，它可以嵌套到第 n 级，并且键“children”应该是一个对象数组，总是。搜索“儿童”：{ . 我希望这是“孩子”：[

这是一个示例响应。可以有多个类似的实例。任何人都可以帮助解决这个问题吗？
