It means "reading" the XML file/string and getting its content according to the structure, usually to use them in a program.
它的意思是“读取”XML 文件/字符串并根据结构获取其内容，通常是在程序中使用它们。
For example if you have this XML fragment:
例如，如果您有这个 XML 片段：
<root>
<node1>value1</node1>
<node2>value2</node2>
</root>
you may want to use these values in a data structure:
您可能希望在数据结构中使用这些值：
ClassRoot:
node1: string
node2: string
so that, in the end:
所以，最后：
Object goofy = ClassRoot.new
parse(xml, goofy)
puts(goofy)
yelds something like:
发出类似的声音：
goofy[node1='value1'; node2='value2']
There are many ways of doing so, like DOM or SAX. You might want to investigate XSLTand xpathas well, according to your needs.

Usually some information is stored in xml documents. In order to use this information in your program you have to parse it - read line by line or node by node and fetch pieces of information.
通常一些信息存储在xml文件中。为了在您的程序中使用此信息，您必须对其进行解析 - 逐行或逐节点读取并获取信息片段。

An XML parser converts an XML document into an XML DOM object - which can then be manipulated with a JavaScript.
XML 解析器将 XML 文档转换为 XML DOM 对象 - 然后可以使用 JavaScript 对其进行操作。
