Question

我在Windows 7上设置java_opts -Xmx512M; 该文件大约是15Mb并且在XMLParsing中失败 - 我正在从命令终端执行（它也在groovyConsole中超时） W 7上正确执行同一文件的短版本

BTW Unchanged XML代码可在24秒内在SunOS 64Bit上正确执行。

你能告诉我在Windows 7上可以做些什么吗？

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

附上完整跟踪：

... file existence validated

看起来错误是访问DTD元素而与大文件大小无关。

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)

groovy 32位Windows无法解析大型XML文件
