xml-config中配置的是每个pdf对应的xml,下边是参数的dtd文档说明
tablepage是xml的root节点,有且只有一个
tablepage的子节点为title和tables
<!ELEMENT tablepage (title,tables)>
//tablepage下可以有多个table,多个table用tables包裹,其子节点用有且只有一个trs
<!ELEMENT tables (table)>
//table子节点能且只能是trs
<!ELEMENT table (trs)>
//table下可以有多个tr,多个tr用trs包裹
<!ELEMENT trs (tr)>
//tr子节点能且只能是tds
<!ELEMENT tr (tds)>
//tds子节点能且只能是td
<!ELEMENT tds (td)>
<!ELEMENT td (text)>
//包含文件,其中file只得是xml-config下的文件路径,不包含xml-config,但要包含.xml后缀,file不能为空.
//被包含文件不能有根节点tablepage
