篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了xml解析开始标记期望R相关的知识,希望对你有一定的参考价值。
我不太了解xml,但我需要读取这个文件,以便R可以使用它。但是,始终存在错误“文档为空,期望开始标记,未找到<”。但我看不出错误的根源。这是xml文件:

答案
我将你的代码复制到RStudio中,用单引号括起来并将其分配给一个对象,“doc”
doc <- '<?xml version="1.0" encoding="UTF-8"?>
<MappingTest xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://sourceforge.net/projects/alevin/ ./Alevin.xsd" xmlns="http://sourceforge.net/projects/alevin/" name="AdvSubgraphTestGenerator2">
<TestGenerator className="tests.generatorTests.AdvSubgraphTestRunner"/>
<ScenarioResult>
<ScenarioParameter name="Waxman_alpha" value="0.4"/>
余数在这里省略
然后以下似乎很好:
test <- htmlTreeParse(doc, useInternal = TRUE)
你想用类似的东西检索doc的一些元素吗?
xpathSApply(doc, "xpath expression", xmlValue, trim = TRUE)
另一答案
标准XML Parser将检查<
作为第一个字符。有可能XML以非标准方式创建,可能具有隐藏字符作为第一个。您将无法在编辑器中看到它打开。
在这种情况下,尝试使用标准文件读取API读取文件的第一个字符,并尝试将字符打印到int
#Scala
import scala.io.Source
val file = Source.fromFile("filename.xml")
file.hasNext match {
case true => println(s"Character int :${file.next.toInt}")
case false => println(s"Empty File")
}
> Character int :65279
这实际上是零宽度不间断空间。
