我有一个我想通过php阅读的xml。文件的形式如下：
myCorpus <- tm_map(myCorpus, stemCompletion,
dictionary = myCorpusCopy, lazy = TRUE)
> tdm <- TermDocumentMatrix(myCorpus, control = list(wordLengths = c(1, Inf)))
Error in UseMethod("meta", x) :
no applicable method for 'meta' applied to an object of class "try-error"
In addition: Warning messages:
1: In mclapply(x$content[i], function(d) tm_reduce(d, x$lazy$maps)) :
all scheduled cores encountered errors in user code
2: In mclapply(unname(content(x)), termFreq, control) :
all scheduled cores encountered errors in user code
问题是它不使用属性。例如，它使用：<?xml version='1.0'?>
<at>
<f>ase
<xx>20160801</xx>
<S>AENE
<G>100000,635</G>
</S>
<I>AAT
<G>171434,245460</G>
<A>103034,12080</A>
<A>103534,15191</A>
</I>
<B>CCF
<G>200000,10000</G>
</B>
<S>GGT
<G>300000,10.4</G>
</S>
<S>HHT
<G>300000,26.4</G>
</S>
</f>
</at>
而不是<S>AENE。
在那种情况下，我没有找到一种方法来获取这些数据：
<S name="AENE"> simplexml_load_string工作正常，但我怎么能拿这个数据呢？ $xml->at->f->S[0]
（并将其放在变量中）。我想要的是能够从xml文件中获取信息。
提前致谢。
答案 0 :(得分：0)
我找到了解决方案。
$xml->f->S[0]
按照我的想法，没有必要在每一行关闭标签。我犯的错误是我在路径中使用了<at>标签。
