nodejs elementtree npm xml解析

Question

我想解析下面的示例XML文件，以獲取一些數據。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> 

從我需要得到所有配置文件（配置文件1，PROFILE2 ...），然後爲每個配置文件的標題標籤，我需要得到它的文本內容，此XML文件。我想才達到服用點是這樣的：下面

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

例如是預期的輸出：

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

我能夠得到的ID。但無法獲取標籤的文字內容。下面是我的代碼：

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

你可以得到這樣的文字：

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

但我也將重構代碼有點不多次調用.findall這樣的：

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

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

 
\t console.log(profile.get('id')); 
 
\t console.log(profile.find('title').text); 
 
}

希望這有助於。
