How To: Write PMXML files

The XML file format supported by Primavera P6 for import and export is known as PMXML.

Writing PMXML files

The sample code below illustrates how to write data to a PMXML file.

JavaC#

package org.mpxj.howto.write;

import org.mpxj.ProjectFile;
import org.mpxj.writer.FileFormat;
import org.mpxj.writer.UniversalProjectWriter;

public class PMXML
{
    public void write(ProjectFile project, String fileName) throws Exception
    {
        new UniversalProjectWriter(FileFormat.PMXML).write(project, fileName);
    }
}

using MPXJ.Net;

namespace MPXJ.Samples.HowToWrite;

public class PMXML
{
    public void Write(ProjectFile project, string fileName)
    {
        new UniversalProjectWriter(FileFormat.PMXML).Write(project, fileName);
    }
}

Writing Multiple Projects

MPXJ supports writing multiple projects to a PMXML file.

JavaC#

package org.mpxj.howto.write;

import org.mpxj.ProjectFile;
import org.mpxj.writer.FileFormat;
import org.mpxj.writer.UniversalProjectWriter;

import java.util.List;

public class PMXML
{   
    public void write(List<ProjectFile> projects, String fileName) throws Exception
    {
        new UniversalProjectWriter(FileFormat.PMXML).write(projects, fileName);
    }
}

using System.Collections.Generic;
using MPXJ.Net;

namespace MpxjSamples.HowToWrite;

public class PMXML
{   
    public void Write(IList<ProjectFile> projects, string fileName)
    {
        new UniversalProjectWriter(FileFormat.PMXML).Write(projects, fileName);
    }
}

Note that when writing multiple projects to a PMXML file, all projects must share the sample ProjectContext. This is normally the case where the projects have been read from the same source.

Using PrimaveraPMFileWriter

If required, the PrimaveraPMFileWriter class can be used directly, which provides access to additional options, as described below.

Baselines

By default baselines are not written to PMXML files. If the ProjectFile instance you are writing contains a baseline, this can be included in the PMXML file by calling the setWriteBaselines method as shown below.

JavaC#

package org.mpxj.howto.write;

import org.mpxj.ProjectFile;
import org.mpxj.primavera.PrimaveraPMFileWriter;

public class PMXMLBaselines
{
    public void write(ProjectFile project, String fileName) throws Exception
    {
        PrimaveraPMFileWriter writer = new PrimaveraPMFileWriter();
        writer.setWriteBaselines(true);
        writer.write(project, fileName);
    }
}

using MPXJ.Net;

namespace MPXJ.Samples.HowToWrite;

public class PMXMLBaselines
{
    public void Write(ProjectFile project, string fileName)
    {
        var writer = new PrimaveraPMFileWriter();
        writer.WriteBaselines = true;
        writer.Write(project, fileName);
    }
}
