Coldfusion 捕获特定的文本字符串并从XML中删除文本字符串

我试图找出如何在下面的XML描述中只显示|和|之间的单词。例如，“网络”或“视频游戏”这个词

我试过这个，但是因为每个单词的长度不同，所以我没有成功。而且，我也不能摆脱|

<cfoutput>#Right(thefeed2.rsschannel.eachresult.resultnumber[x].metadata.xmlAttributes.v, 10)#</cfoutput>

#对（offeed2.rsschannel.eachresult.resultnumber[x].metadata.xmldattributes.v，10）#

我还试图做一个相反的任务——过滤掉|和|之间的单词，这样它就不会显示。换句话说，以第一个项目为例，显示整个描述，减去“web”或“视频游戏”一词

我已经试过了，但同样的问题是，我只想过滤掉描述，在|和|之间没有单词

<cfoutput>#left(thefeed2.rsschannel.eachresult.resultnumber[x].metadata.xmlAttributes.v, 500)#</cfoutput>

#左（offeed2.rsschannel.eachresult.resultnumber[x].metadata.xmldattributes.v，500）#

所以我的问题是

1：如何从description元素中提取|和|之间的单词

2：在数字1的另一个例子中，如何删除描述中|和|之间的单词

顺便说一下，“offeed2”就是我所说的XML提要

是否总是只有两个

|

符号？如果是这样，您可以使用

GetToken

查找值

<cfset Mystring = GetToken(variable,1,'|') />

GetToken

将变量视为一个带有分隔符

|

---

要删除单词，可以使用

replace（variable，Mystring，”）

要使用regex和REreplace（）。示例（cfscript中）：

(一)

(二)

---

regex

\\\\\\\\\

将匹配以

开头和结尾的任何文本。对于字符串操作，总是后退一步寻找模式来帮助您获得创造性。例如，CFMLs的“列表”概念带来了一些乐趣。更高级的用户总是直接使用正则表达式，但如果您刚刚开始，这肯定是一个高级主题。我立刻认出您的字符串是一个由管道（|）分隔的列表。您还可以看到，句子是由空格分隔的单词列表。下面是一些代码

 //set your string to something
 <cfset myString = "thefeed2.rsschannel.eachresult.resultnumber[x].metadata.xmlAttributes.v" />
//now let's treat the phrase as a list, we'll get position 2 of the list.
<cfset myWord = listGetAt(myString,2,'|');
//assuming you don't want the pipes in the clean string, let's just do a fast replace once
<cfset cleanString = replace(myString,"|#myWord#|","") />
//if you do want the pipes then you'll need a regex (a more advanced topic)
<cfset cleanStringWithPipes = rereplace(myString,"(\|)[ A-Za-z0-9]+(\|)","\1\2") />

//将字符串设置为
//现在让我们把这个短语当作一个列表，我们将得到列表的第2位。
谢谢，第二个代码运行得很好！我相信第一个是完全相同的，只是文本的替换。我可能解释得很糟糕，但对于第一个，我想提取并显示单词，而不是替换它。例如，我想显示单词“web”或“VideoGames”，并删除描述中的其余文本，以提取匹配的文本。另外，
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\/code>可能比
\\\\\\\\\\\\/code>更有意义。很酷，我以前从未听说过GetToken，非常有趣！我尝试了以下方法，但它删除了“web”一词，而不是描述的其余部分。我做错了什么#GetToken（offeed2.rsschannel.eachresult.resultnumber[1].metadata.xmlAttributes.v，1，“|”）#我建议您向沙盒大师请教：甜心，谢谢，这非常有效！！！我的词在|和|中给出了一个词，而cleanString给出了一个没有这个词的好的、干净的字符串！不要
重新替换（myString），“（\）[A-Za-z0-9]+（\）”，“\1\2”）
-这很愚蠢。如果你这样做的话，只需重新替换（myString，\\\[A-Za-z0-9]+\\\\\\”，“\\\\\”）
。愚蠢还是可怕？我应该听从自己的建议，退后一步。
origString = thefeed2.rsschannel.eachresult.resultnumber[x].metadata.xmlAttributes.v;
newString = REreplace(origString, "\|.*\|", "");

 //set your string to something
 <cfset myString = "thefeed2.rsschannel.eachresult.resultnumber[x].metadata.xmlAttributes.v" />
//now let's treat the phrase as a list, we'll get position 2 of the list.
<cfset myWord = listGetAt(myString,2,'|');
//assuming you don't want the pipes in the clean string, let's just do a fast replace once
<cfset cleanString = replace(myString,"|#myWord#|","") />
