徹底解決Eclipse中XML驗(yàn)證速度過慢甚至造成死機(jī)的問題
新建user_catalog.xml
（其中I:/Eclipse/CommonPlugins/DTD/ 目錄下放置各種從網(wǎng)上下載的dtd文件）
如想添加新的dtd文件，修改此配置文件即可。

方法一：將此文件直接放在 D:\Eclipse\workspace\.metadata\.plugins\org.eclipse.wst.xml.core\目錄
下，eclipse 自動(dòng)識(shí)別。
方法二：手動(dòng)導(dǎo)入此文件，菜單 myeclipse->preferences->MyEclipse->Files and Editors->XML->xml catalog
選擇 user specified entries 點(diǎn) Add->Next Catalog 添加user_catalog.xml
