时髦的 32 位 Windows 无法解析大型 XML 文件

Question

我在Windows 7 java_opts-Xmx512M上设置;该文件大约是 15Mb，并且在 XML 中失败 - 我从命令终端执行（它在 groovyConsole 中也超时）同一文件的短版本在 W 7 上正确执行

顺便说一句，未更改的XML代码在24秒内在SunOS 64位上正确执行。

• 你能告诉我我可以在 Windows 7 上做什么吗？

代码片段：

import groovy.util.XmlParser
import javax.xml.xpath.*
import groovy.time.*
inpXMLFile='c:/EnvFiles/CCC.xml'
entry=new File("$inpXMLFile")
assert   entry.exists()
println " ... file existence validated"
...
def node= new XmlParser().parse( new File( inpXMLFile ) ) // Line 23 
// .... the rest of the script

附有完整跟踪：

... file existence validated

Answer 1

看起来错误正在访问 DTD 元素，与大文件大小无关。

java.net.ConnectException: Connection timed out: connect
com.sun.org.apache.xerces.internal.impl.XMLEntityManager.startDTDEntity

您有两种选择：1. 您可以删除或注释掉 XML 文件中的 DTD 引用和实体，或者2. 禁用在 XMLParser（格式）上解析 DTD 和外部实体。

def parser = new XmlParser()
parser.setFeature("http://apache.org/xml/features/nonvalidating/load-dtd-grammar", false)
parser.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false)
