从jsp读取xml [英] read xml from jsp

问题描述

让我说我有一个像这样的xml文件"path.xml":

lets say i have an xml file "path.xml" that goes like this:

<paths>
   <path id="first">
      <url>http://blablabla</url>
   </path>
   <path id="second">
      <url>http://blablabla</url>
   </path>
</paths>

我有一个jsp文件，我想从中读取基于id的url. 例如: 我想在jsp文件中编写一些Java代码，例如:字符串path =从xml文件中获取"url"，其中path id ="second".

i have a jsp file from which i want to read url based on the id. for example: i want to write in the jsp file some java code like:String path = get from xml file the "url", where path id = "second".

这在jsp中如何完成?我对使用jsp进行Dom解析不是很有经验

how is this done in jsp? i am not very experienced with Dom parsing in jsp

非常感谢:)

推荐答案

您可以使用

You could use XML Tag Library :

<x:parse doc="path.xml" var="doc" scope="application"/>
<x:out select="$doc/paths/path[id='second']/url"/>
