## Validating PSI-MI 2.5 file with MIF25 XML schema

### Description

The function validates given PSI-MI 2.5 file with MIF25 XML schema provided by the Molecular Interactions Workgroup of HUPO Proteomics Standards Initiative

### Usage

    validatePSIMI25(file,
    schema = system.file("extdata/schemas/MIF25.xsd", package = "RpsiXML"),
    ignore.stderr = TRUE)

### Arguments

`file` | The name or the URL of the file to be validated
`schema` | The schema file of PSI-MI 2.5 file format by default
`ignore.stderr` | Whether to print out errors in the console

### Details

We advice to set "ignore.stderr=FALSE" for the first time of validating. The error number of the file will be printed in the console. When the number is not 0, one can set "ignore.stderr=TRUE" and see the errors produced during the validation.

### Value

The number of errors in validating the file

### Note

This function sofar depends on the tool "xmllint" bundled with libxml2 library. We plan to compile it later to run independent of the tool.
