This sample code shows parsing PDF document to extract Form fields as XML


import path from 'node:path';

export {ParseExportFormsAsXML};

const pdfApi = new PdfApi(APP_SID, APP_KEY);

const ParseExportFormsAsXML = {
    async uploadDocument (documentName, localFolder, tempFolder) {
        const fileNamePath = path.join(localFolder, documentName);
        const fileData = await fs.readFile(fileNamePath);
        const storagePath = path.join(tempFolder, documentName);
        await pdfApi.uploadFile(storagePath, fileData)
            .then(() => console.log("File: '" + documentName +"' successfully uploaded."));
    },
    async downloadResult(resultName, localFolder, tempFolder, prefix) {
        const fileName = path.join(tempFolder, resultName);
        const changedPdfData = await pdfApi.downloadFile(fileName);
        const filePath = path.join(localFolder, prefix + resultName);
        await fs.writeFile(filePath, changedPdfData.body);
        console.log("Downloaded: " + filePath);
    },

    async export(documentName, outputXMLName, localFolder, remoteFolder) {
	if ( pdfApi ) {
            await uploadDocument(documentName, localFolder, remoteFolder);

            const xmlPath = path.join(remoteFolder, outputXMLName)
            const response = await pdfApi.putExportFieldsFromPdfToXmlInStorage( documentName, xmlPath, null, remoteFolder );

            if (response.body.code == 200) {
                console.log("ParseExportFormsAsXML(): Pdf document '" + documentName + "' form fields successfully exported to '" + outputXMLName + "' file!");
                await downloadResult(outputXMLName, localFolder, remoteFolder, "");
            }
            else
                console.error("ParseExportFormsAsXML(): Unexpected error!") 

        }
    }
};
