To parse tables from XML documents using GroupDocs.Parser, follow these easy steps in your Java environment:
// Load the input document with Parser that includes table elements
try (Parser parser = new Parser("input.xml"))
{
// Verify that the document type allows table recognition
if (!parser.getFeatures().isTables()) {
System.out.println("Add logic for files that don’t support tables");
return;
}
// Define rules for interpreting table structure
TemplateTableLayout layout = new TemplateTableLayout(
java.util.Arrays.asList(new Double[]{50.0, 95.0, 275.0, 415.0, 485.0, 545.0}),
java.util.Arrays.asList(new Double[]{325.0, 340.0, 365.0, 395.0}));
// Set parameters to extract tables
PageTableAreaOptions options = new PageTableAreaOptions(layout);
// Run table extraction on the loaded document
Iterable<PageTableArea> tables = parser.getTables(options);
// Process each extracted table from the result
for (PageTableArea t : tables)
{
}
}

Beyond reading tables, GroupDocs.Parser supports capturing plain text, visual elements, embedded metadata, and structured objects to enhance document processing tasks.
Support for extracting tables from standard document types like PDF, Word, Excel, and HTML with high accuracy.
Retrieve table data from spreadsheets, documents, and reports while preserving the structure and alignment.
Control layout detection, manage headers and footers, and fine-tune extraction with flexible configuration options.
This example shows how to extract and loop through table content in an Excel (XLSX) file using GroupDocs.Parser.
// Initialize Parser with the Excel file
try (Parser parser = new Parser("input.pdf"))
{
// Exit if table extraction isn’t supported for this document
if (!parser.getFeatures().isTables())
{
return;
}
// Apply rules to locate table layout
TemplateTableLayout layout = new TemplateTableLayout(
java.util.Arrays.asList(new Double[]{50.0, 95.0, 275.0, 415.0, 485.0, 545.0}),
java.util.Arrays.asList(new Double[]{325.0, 340.0, 365.0, 395.0}));
// Configure settings for table extraction
PageTableAreaOptions options = new PageTableAreaOptions(layout);
// Invoke the extraction process
Iterable<PageTableArea> tables = parser.getTables(options);
// Loop over all parsed table structures
for (PageTableArea t : tables)
{
// Iterate over each row within the table
for (int row = 0; row < t.getRowCount(); row++)
{
// Process each cell in the current row
for (int column = 0; column < t.getColumnCount(); column++)
{
// Access and read the current cell's content
PageTableAreaCell cell = t.getCell(row, column);
if (cell != null)
{
// Output the textual value of each table cell
System.out.print(cell.getText());
System.out.print(" | ");
}
}
}
}
}
