XML Conversion Services

Professional XML Conversion Services for Document Tagging, Data Transformation and Schema-Compliant Output

We provide expert XML conversion outsourcing solutions for publishers, technology companies, healthcare organisations, government agencies and businesses that need documents converted to XML, data files structured in XML format, content tagged according to specific schemas and XML output validated against defined DTDs or XSD specifications. XML is the structured data format underlying document publishing, system integration, regulatory data submission and electronic data interchange — and correctly structured, schema-compliant XML is the specific outcome that matters.

Our professional offshore XML conversion team in India has extensive experience with document XML schemas (JATS, DITA, DocBook, TEI, custom DTDs), data exchange XML formats (OAGIS, UBL, HL7, SWIFT, custom schemas) and content management XML structures. Every conversion is validated before delivery — schema errors found at delivery are significantly cheaper to fix than errors found after downstream system import.

Both single-document conversion projects and bulk XML processing arrangements for regular content pipelines are fully supported.

Service Overview

Expert XML conversion producing schema-compliant, validated output for every downstream use case

Schema and DTD specification review
Source document structure analysis
Element and attribute mapping development
Manual tagging with systematic review
Schema validation before delivery
Documentation and mapping record

XML conversion quality is determined by schema compliance — not by whether the output looks reasonable, but by whether it validates correctly against the specified schema and produces correct results in the downstream system that consumes it. Errors that look minor in the XML source can cause significant issues downstream: a missing required element fails import validation; an incorrect attribute value type is rejected; a namespace declaration error prevents schema resolution.

We validate every conversion against the specified schema or DTD before delivery, identify and correct all validation errors in the produced XML and document the element mapping decisions made during conversion so your team has a reference for understanding the output structure.

Our India-based XML conversion team serves academic and scientific publishers, healthcare IT companies, legal publishers, enterprise content management operations and government data exchange programmes.

XML Services

Expert XML Conversion Solutions for Every Schema and Use Case

Each XML conversion is built around your specific schema, validated before delivery and documented for downstream use.

Document XML conversion and tagging

We convert document content — from Word, PDF, InDesign, plain text and HTML sources — into structured XML following your document schema specification. Document XML conversion applies the schema's structural elements to the document hierarchy: identifying section levels for section element nesting, distinguishing body content from front matter and back matter, applying inline elements for emphasis, citations, cross-references, defined terms and other inline markup, handling tables and figures with the schema's table and figure models and applying required metadata elements in the header section. For each document type and schema combination, we develop an element mapping document before production so tagging decisions are consistent and reviewable.

Data file XML conversion

We convert structured data files — Excel, CSV, JSON, SQL exports and other structured formats — into XML formatted for data exchange, API consumption, regulatory submission or system import. Data file XML conversion requires mapping source data fields to XML elements and attributes, applying correct namespace declarations, structuring repeating records correctly within the XML document model, handling null and missing values according to the schema's rules and validating the output against the schema or a well-formed XML check for custom formats. For EDI and business data exchange formats, we confirm the specific standard version and profile before conversion.

JATS, DITA and document publishing XML

We convert journal articles, technical documentation and structured publishing content to JATS, DITA and DocBook schemas. JATS conversion covers journal article XML for PubMed and other repository submissions. DITA conversion covers technical documentation structured for content management systems that consume DITA topic architecture. DocBook conversion covers technical books and documentation. Each schema has specific element vocabularies, structural requirements and metadata models that our XML team applies from documented schema knowledge.

XML validation, repair and schema migration

We audit existing XML files for schema compliance, validate against current DTD or XSD specifications, identify and correct validation errors, repair malformed XML and migrate XML structured according to deprecated or outdated schema versions to current schema requirements. XML validation projects are common when XML was produced by older tools using deprecated schema versions, when schema requirements have been updated since the original conversion and when automated XML generation has introduced systematic structural errors that affect downstream processing.

Custom schema XML development

We develop XML structures to custom schema specifications for content management, data interchange and regulatory submission use cases where no standard schema applies. Custom XML development begins from your element and attribute specification, produces a sample XML structure for your technical team's review and validation, refines based on feedback and produces the final validated output. For custom schemas without a formal DTD or XSD, we document the agreed element structure as a reference for ongoing consistency.

How It Works

How we manage XML conversion projects

Source Quality Assessment

Sample of your source files reviewed to determine document type, image quality, language, layout complexity and expected conversion accuracy. Realistic expectations confirmed before work is quoted or committed.

NDA and Secure Setup

NDA before files are shared. For regulated content types — legal, medical, financial — specific handling requirements documented before production begins.

Pilot Conversion

Representative sample converted and returned for your review. Output format, accuracy level, exception handling and source-specific issues confirmed before full production proceeds.

Batch Production with Manual Correction

Full archive converted in defined batches. Manual correction applied throughout production — not as a post-processing step. Correction is systematic and applied to every page, not sampled.

Exception Documentation

Pages where source quality limits achievable accuracy documented specifically with page reference and issue noted. Output validated against target format requirements before delivery.

Delivery with Validation Report

Converted files delivered alongside accuracy summary, exception documentation and — for XML projects — schema validation report confirming compliance before submission to your system or publisher.

Need documents or data converted to validated XML?

Share a sample source document and your schema specification. We convert a free sample section and validate it so you can review element mapping and schema compliance.

Why Outsource to SDES?

Why organisations outsource OCR, PDF and document conversion to SDES India

Source quality assessed upfront — realistic accuracy expectations given, not generic promises
Manual correction applied to every page — never sampling-based review only
Output format tested against your target system before full production
Schema validation included in every XML and structured conversion project
Large archive conversions tracked by coverage and delivered in batches
Exception documentation for pages where source limits achievable accuracy

Automated conversion tools produce output that requires correction. The gap between raw OCR output and reliably accurate, searchable text is significant and source-dependent — it only matters if you account for it. Our process always combines conversion tools with systematic manual review so the output you receive is ready to use rather than ready to correct.

We give clients realistic accuracy expectations based on their actual source files before any project commitment. If your source has characteristics that limit achievable accuracy, we tell you upfront rather than quoting a generic accuracy figure that does not apply to your specific documents.

Quality and Security

Accurate output, handled securely

NDA before any source documents are shared. For legal, financial, medical and personally identifiable content, access is restricted to the conversion team assigned to your project. Source documents are not retained beyond the delivery period.

Manual correction is not sampling-based — every page of output is reviewed against the source before delivery. Pages where source quality prevents reliable conversion are flagged with specific notes rather than delivered with silent errors mixed into the clean output.

For JATS XML and medical publication conversion, output is validated against current PMC schema requirements before delivery. Schema errors are corrected before the file leaves our team. For other XML schemas, validation runs against your specified DTD or XSD.

Client Feedback

What clients say about our XML conversion work

★★★★★

220 journal articles needed JATS XML conversion for PubMed Central. SDES assessed a sample, ran a pilot and validated before production. PMC submission achieved 97% first-pass acceptance. The three needing revision had missing DOI data in our source — SDES flagged this during production, not after submission.

Editorial Production Manager Biomedical Publisher, USA

★★★★★

1,200 mixed PDF financial statements needed consistent Excel extraction. SDES identified the source type distribution, gave us different accuracy expectations for each type and delivered with source type indicated. That transparency let us apply the right level of review to each segment.

Finance Systems Manager Accounting Practice, UK

★★★★★

A 40-year archive of legal correspondence — 28,000 scanned pages — had been digitised without metadata. SDES converted and indexed the full collection in six weeks. OCR correction was applied consistently and indexing was accurate throughout, not just on recent documents.
