parsePsimi25Interaction {RpsiXML} | R Documentation

## Parsing PSI-MI 2.5 XML documents into interactions

### Description

The PSI-MI 2.5 XML format is used widely by many repositories to record protein-protein interaction data as well as protein complex data. This functions parse such files into interactions or complexes.

`parsePsimi25Interaction` is the parser for interaction data and `parsePsimi25Complex` is the parser for complex data.

### Usage

    parsePsimi25Interaction(psimi25file, psimi25source, verbose=TRUE)
    parsePsimi25Complex(psimi25file, psimi25source, verbose=FALSE)

### Arguments

`psimi25file` | character, file name or URL of the XML document
`psimi25source` | A supported data repository source, see also `psimi25Source-class`
`verbose` | logical, whether the parsing state should be displayed verbosely.

### Value

`psimi25Interaction` returns a list of `psimi25InteractionEntry` objects, each represents one `entry` in the XML document `psimi25Complex` returns a `psimi25ComplexEntry` objects, representing the complex data from one XML document.
