[R] xmlEventParse returning trimmed content?

[Johannes Graumann]

Hello,

I wrote the function below and have the problem, that the "text" bit returns 
only a trimmed version (686 chars as far as I can see) of the content under 
the "fetchPeaks" condition.
Any hunches why that might be?

Thanks for pointer, Joh

xmlEventParse(fileName,
    list(
      startElement=function(name, attrs){
	if(name == "scan"){
	  if(.GlobalEnv$ms2Scan == TRUE & .GlobalEnv$scanDone == TRUE){
	    cat(.GlobalEnv$scanNum,"\n")
	    MakeSpektrumEntry()
	  }
	  .GlobalEnv$scanDone <- FALSE
	  .GlobalEnv$fetchPrecMz <- FALSE
	  .GlobalEnv$fetchPeaks <- FALSE
	  .GlobalEnv$ms2Scan <- FALSE
	  if(attrs[["msLevel"]] == "2"){
	    .GlobalEnv$ms2Scan <- TRUE
	    .GlobalEnv$scanNum <- as.integer(attrs[["num"]])
	  }
	} else if(name == "precursorMz" & .GlobalEnv$ms2Scan == TRUE){
	  .GlobalEnv$fetchPrecMz <- TRUE
	} else if(name == "peaks" & .GlobalEnv$ms2Scan == TRUE){
	  .GlobalEnv$fetchPeaks <- TRUE
	}
      },
      text=function(text){
	if(.GlobalEnv$fetchPrecMz == TRUE){
	  .GlobalEnv$precursorMz <- as.numeric(text)
	  .GlobalEnv$fetchPrecMz <- FALSE
	}
	if(.GlobalEnv$fetchPeaks == TRUE){
	  .GlobalEnv$peaks <- text
	  .GlobalEnv$fetchPeaks <- FALSE
	  .GlobalEnv$scanDone <- TRUE
	}
      }
    )
  )
