除了上面的示例，您还可以尝试使用linq到xml

见下文。

    var str = @"<ALEXA VER='0.9' URL='google.com/' HOME='0' AID='='>

<SD TITLE='A' FLAGS='DMOZ' HOST='google.com'> 
<TITLE TEXT='Google                             '/> 
<ADDR STREET='' CITY='' STATE='' ZIP='' COUNTRY='' />
<CREATED DATE='15-Sep-1997' DAY='15' MONTH='09' YEAR='1997'/>
<PHONE NUMBER='unlisted'/>
<OWNER NAME='unlisted'/>
<EMAIL ADDR='dns-admin@google.com'/>
<LANG LEX='en'/>
<LINKSIN NUM='704402'/>
<SPEED TEXT='1581' PCT='48'/>
<REVIEWS AVG='4.5' NUM='524'/>
<CHILD SRATING='0'/>
<ASSOCS>
<ASSOC ID='googlecom'/></ASSOCS>
</SD>

<KEYWORDS>
<KEYWORD VAL='Mountain View'/>
</KEYWORDS><DMOZ>
<SITE BASE='google.com/' TITLE='Google' DESC='Enables users to search the Web, Usenet, and images. Features include PageRank, caching and translation of results, and an option to find similar pages. The companys focus is developing search technology.'>
<CATS>
<CAT ID='Top/Computers/Internet/Searching/Search_Engines/Google' TITLE='Search Engines/Google' CID='374822'/>
<CAT ID='Top/Regional/North_America/United_States/California/Localities/M/Mountain_View/Business_and_Economy/Industrial/Computers_and_Internet' TITLE='Industrial/Computers and Internet' CID='625367'/>
<CAT ID='Top/World/Arabic/إقليمـي/الشرق_الأوسط/السعودية/تجارة_و_أقتصاد/كمبيوتر_و_إنترنت/محركات_بحث' TITLE='كمبيوتر و إنترنت/محركات بحث' CID='204954'/>
<CAT ID='Top/World/Français/Informatique/Internet/Recherche/Moteurs_de_recherche/Google' TITLE='Moteurs de recherche/Google' CID='247347'/>
</CATS>
</SITE>
</DMOZ>
<SD>
<POPULARITY URL='google.com/' TEXT='1'/>
<REACH RANK='1'/>
<RANK DELTA='+0'/>
</SD>
</ALEXA>";

    var item = XElement.Parse(str);

    var subSet = item.Elements("SD");

    var actualItem =  subSet.Where(x => x.Element("POPULARITY") != null).First();

    var value = actualItem.Element("POPULARITY").Attribute("TEXT").Value;

希望这可以帮助

Answer 2

像这样的东西：

XmlDocument doc = new XmlDocument();
doc.LoadXml( @"<SD> <POPULARITY URL=""google.com/"" TEXT=""1""/> <REACH RANK=""1""/> <RANK DELTA=""+0""/> </SD> ");

XmlNode root = doc.FirstChild;

Debug.WriteLine(root["POPULARITY"].Attributes["TEXT"].InnerXml);

Answer 3

你可以试试：

XmlDocument doc = new Xmldocument(); 
doc.Load(stringWithYourXml);

XmlNode node = doc.SelectSingleNode("/SD/POPULARITY");
var val = node.Attributes["TEXT"].Value
