我正在尝试从预定义列表中获取多个网页。 这是代码:
<?xml version="1.0" encoding="UTF-8"?>
<config>
<script>
<![CDATA[
String[] codes = new String[] {"18","21","24","25","26"};
SetContextVar("codes", codes);
]]>
</script>
<loop item="link">
<list>
<var name="codes" />
</list>
<body>
<var-def name="webpage">
<html-to-xml>
<http url="${sys.fullUrl('http://www.someurl.com/',link)}"/>
</html-to-xml>
</var-def>
</body>
</loop>
</config>
,错误是“变量赋值:代码:无法将org.webharvest.runtime.variables.ListVariable分配给java.lang.String”
我在这里缺少什么?
答案 0 :(得分:1)
请尝试这个例子:
<config>
<var-def name="Codes">
<![CDATA[<Codes>]]>
<![CDATA[<Code>]]>18<![CDATA[</Code>]]>
<![CDATA[<Code>]]>21<![CDATA[</Code>]]>
<![CDATA[<Code>]]>24<![CDATA[</Code>]]>
<![CDATA[<Code>]]>25<![CDATA[</Code>]]>
<![CDATA[</Codes>]]>
</var-def>
<loop item="CodesLoop" index="i">
<list>
<xpath expression="//Code/text()">
<var name="Codes"/>
</xpath>
</list>
<body>
<file action="write" path="D:\ABC\${CodesLoop}.txt" charset="UTF-8">
<template>${CodesLoop}</template>
</file>
</body>
</loop>
</config>
