README

TMX 1.4b parser and writer for the OpenCAT Framework.

Converts between TMX files and TranslationUnit objects. Used by opencat/translation-memory for import and export. You can also use it standalone for TMX manipulation.

Installation

composer require opencat/tmx

Requires ext-dom, ext-libxml, and ext-xmlreader.

Reading TMX files

DOM mode — small files (up to ~10,000 TUs)

use CatFramework\Tmx\TmxReader;

$reader = new TmxReader();
$units = $reader->read('memory.tmx');  // returns TranslationUnit[]

foreach ($units as $unit) {
    echo $unit->sourceLanguage . ' → ' . $unit->targetLanguage . PHP_EOL;
    echo $unit->source->getPlainText() . PHP_EOL;
    echo $unit->target->getPlainText() . PHP_EOL;
}

Streaming mode — large files (100k+ TUs)

Uses XMLReader internally; yields one TranslationUnit at a time without loading the full document into memory.

foreach ($reader->stream('large-memory.tmx') as $unit) {
    // process $unit — only one TU is in memory at a time
    $tm->store($unit);
}

Writing TMX files

use CatFramework\Tmx\TmxWriter;
use CatFramework\Core\Model\TranslationUnit;

$writer = new TmxWriter();
$writer->write($units, 'exported.tmx');  // $units is TranslationUnit[]

Inline code support

TMX inline elements are mapped to InlineCode objects:

TMX element	InlineCode type	Notes
`<bpt>`	`OPENING`	Begin paired tag (bold open, link open, etc.)
`<ept>`	`CLOSING`	End paired tag
`<ph>`	`STANDALONE`	Standalone placeholder (line break, etc.)
`<it pos="begin">`	`OPENING`, isolated	Isolated tag (tag boundary crossed a TU)
`<it pos="end">`	`CLOSING`, isolated	Isolated tag

The i attribute is used as the InlineCode::$id pairing key (equivalent to XLIFF's rid).

Language matching

The srclang attribute on the <header> determines which <tuv> is the source. Matching is:

Exact case-insensitive match ("en-US" == "EN-US")
Prefix match (srclang="en" matches xml:lang="en-US")
First <tuv> if no match

TMX file structure

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE tmx SYSTEM "tmx14.dtd">
<tmx version="1.4">
  <header srclang="en-US" .../>
  <body>
    <tu tuid="1" creationid="translator@example.com" creationdate="20240101T120000Z">
      <prop type="x-domain">Legal</prop>
      <tuv xml:lang="en-US"><seg>Source text.</seg></tuv>
      <tuv xml:lang="fr-FR"><seg>Texte cible.</seg></tuv>
    </tu>
  </body>
</tmx>

<prop> elements are stored in TranslationUnit::$metadata. The creationid attribute maps to TranslationUnit::$createdBy.
