nodejs elementtree npm xml解析

Question

我正在尝试解析下面的示例XML文件，从中获取一些数据。下面是XML文件：

<Benchmark xmlns="http://checklists.nist.gov/xccdf/1.1" xmlns:xsi="www.w3.org/2001/XMLSchema-instance" id="SAP-HANA" resolved="1" xml:lang="en-US">
 <status date="2016-03-17">draft</status>
 <title xmlns:xhtml="http://www.w3.org/1999/xhtml" xml:lang="en-US">Guide to the Secure Configuration of SAP HANA</title>
 <version>0.1.28</version>

 <Profile id="profile1">
    <title xmlns:xhtml="http://www.w3.org/1999/xhtml" xml:lang="en-US">text1</title>
    <select idref="This is rule 1" selected="true"/>
    <set-value idref="ssfs_master_key_timeout">20</set-value>
 </Profile> 

 <Profile id="profile2">
    <title xmlns:xhtml="http://www.w3.org/1999/xhtml" xml:lang="en-US">text2</title>
    <select idref="this is rule1" selected="true"/>
    <select idref="this is rule1" selected="true"/>
    <select idref="this is rule1" selected="true"/>
 </Profile>
</Benchmark>

从这个XML文件中，我需要获得所有的配置文件(profile1、profile2...)然后，对于每个配置文件的title标记，我需要获取其文本内容。我正在尝试实现这样的东西：

for all profile in XML{
    get its attribute "id".
    get its <title> tag's text content.
}

例如，以下是预期输出：

profile1
text1
profile2
text2  // but in my code, it is always coming text1. I am not aware of, how to place [i] 

我能拿到身份证。但不能获得其标签的文本内容。下面是我的代码：

var fs = require('fs'); 
var et = require('elementtree'); 
var XML = et.XML;
var ElementTree = et.ElementTree;
var element = et.Element;
var subElement = et.SubElement;

var data, etree;

data = fs.readFileSync('my.xml').toString();
etree = et.parse(data);
var length = etree.findall('./Profile').length;
for (var i = 0; i < length; i++) {
    console.log(etree.findall('./Profile')[i].get('id'));
    console.log(etree.findtext('./Profile/title'));  // dont know, where to place [i]

//  var profile = etree.findall('./Profile')[i].get('id');
//  console.log(etree.findtext('./Profile'[@id=’profile’]'/title'));

    //console.log(etree.findall('./Profile'[i]'/title'));
    //console.log(list[i]);
}

Answer 1

你可以像这样得到文本：

console.log(etree.findall('./Profile')[i].find('title').text);

但我也会对代码进行一点重构，以避免像下面这样多次调用.findall：

​

var profiles = etree.findall('./Profile');

for (var i = 0; i < profiles.length; i++) {
	var profile = profiles[i];

	console.log(profile.get('id'));
	console.log(profile.find('title').text);
}

​

希望这能有所帮助。
