采用的xml文件为:second.xml
<?xml version="1.0" encoding="gb2312"?>
<!DOCTYPE employee_data [

<!ELEMENT name (#PCDATA)>
<!ELEMENT age (#PCDATA)>
<!ELEMENT sex (#PCDATA)>
<!ELEMENT address (#PCDATA)>
<!ELEMENT E_mail (#PCDATA)>
<!ELEMENT Photo EMPTY>
<!NOTATION jpg SYSTEM "C:\windows\system32\mspaint.exe">
<!ENTITY mm_photo SYSTEM "mm_photo.jpg" NDATA jpg>
<!ATTLIST photo picture ENTITY #IMPLIED>
<!ATTLIST photo sw_tool NOTATION (jpg) #IMPLIED>
]>
<employee_inf>
   <employee_data>

      <E_mail> mlh123caoer@tom.com</E_mail>
      <photo picture="mm_photo" sw_tool="jpg"/>
   </employee_data>
