System.out.println(io.getMessage());
} catch (JDOMException jdomex) {

[/code]

仍是有錯？有在想是不是沒安裝JDOM與設定路徑？

目前將http://jdom.org/dist/binary/

的jdom-1.1.2.zip擋下載了。

可以請教一下怎麼安裝與設定路徑嗎？

感激不盡<(_ _)>]]> https://forum.andowson.com/posts/preList/570/1199.page https://forum.andowson.com/posts/preList/570/1199.page GMT [code=java; first-line:13]File xmlFile = new File("C:\\JAVA_WORK\\test3.xml");[/code]
第19行改為
[code=java; first-line:19]List list = rootNode.getChildren("ROW");[/code]
即可正常輸出您要的結果。

至於jdom-1.1.2.jar檔的安裝或設定其實主要是要設定在CLASSPATH這個環境變數上，例如您可以將jdom-1.1.2.zip解壓縮，然後將jar檔複製到於C:\JAVA_WORK\lib目錄下，然後在CLASSPATH中加入C:\JAVA_WORK\lib\jdom-1.1.2.jar。]]> https://forum.andowson.com/posts/preList/570/1200.page https://forum.andowson.com/posts/preList/570/1200.page GMT

懇請指點一下，謝謝<(_ _)>]]> https://forum.andowson.com/posts/preList/570/1201.page https://forum.andowson.com/posts/preList/570/1201.page GMT http://caterpillar.onlyfun.net/Gossip/JavaEssence/WhatClasspath.html

先弄清楚什麼是CLASSPATH後，這個問題您應該就可以自行處理了。]]> https://forum.andowson.com/posts/preList/570/1202.page https://forum.andowson.com/posts/preList/570/1202.page GMT
