PHP-XML: How do I modify text value of a given target
Question
<?xml version="1.0" encoding="utf-8" ?>
<xliff>
<body>
<trans-unit id="NFDBB2FA9-tu4" xml:space="preserve">
<source xml:lang="en">He</source>
<target xml:lang="id">He</target>
</trans-unit>
<trans-unit id="NFDBB2FA9-tu5" xml:space="preserve">
<source xml:lang="en">She</source>
<target xml:lang="id">She</target>
</trans-unit>
</body>
<body>
<trans-unit id="NFDBB2FA9-tu6" xml:space="preserve">
<source xml:lang="en">They</source>
<target xml:lang="id">They</target>
</trans-unit>
<trans-unit id="NFDBB2FA9-tu7" xml:space="preserve">
<source xml:lang="en">We</source>
<target xml:lang="id">We</target>
</trans-unit>
</body>
</xliff>
how do I modify value of <target> of trans-unit id="NFDBB2FA9-tu7" or any other?
done this but empty on the print_r and don't know what's next
$dom = new \DOMDocument();
$dom->load("my.xlf");
$root = $dom->documentElement;
$xliffBodies = $root->getElementsByTagName("body")->item(0);
foreach ($xliffBody as $body) {
$el = $body->getElementsByTagName("trans-unit");
print_r($el);
}

The code below is using a string representation of the original XML file ( my.xlf ) for convenience - change the loadXML for load to load your file.
If you use an XPath expression you can target these elements directly - though here I targeted the trans-unit node initially before selecting the child node - target
<?php
$strxml='<?xml version="1.0" encoding="utf-8" ?>
<xliff>
<body>
<trans-unit id="NFDBB2FA9-tu4" xml:space="preserve">
<source xml:lang="en">He</source>
<target xml:lang="id">He</target>
</trans-unit>
<trans-unit id="NFDBB2FA9-tu5" xml:space="preserve">
<source xml:lang="en">She</source>
<target xml:lang="id">She</target>
</trans-unit>
</body>
<body>
<trans-unit id="NFDBB2FA9-tu6" xml:space="preserve">
<source xml:lang="en">They</source>
<target xml:lang="id">They</target>
</trans-unit>
<trans-unit id="NFDBB2FA9-tu7" xml:space="preserve">
<source xml:lang="en">We</source>
<target xml:lang="id">We</target>
</trans-unit>
</body>
</xliff>';
$dom=new DOMDocument;
$dom->loadXML($strxml);
$xp=new DOMXPath($dom);
$xp->registerNamespace('xml','http://www.example.com');
$col=$xp->query( '//xliff/body/trans-unit' );
if( $col && $col->length ){
foreach( $col as $node ){
$target=$xp->query('target',$node)->item(0);
$target->nodeValue='banana';
}
}
printf('<textarea cols=50 rows=10>%s</textarea>',$dom->saveXML());
?>
A simple edit - change the target value to the word banana yields:
The original snippet of XML is a little different from the actual XML in that there are namespace declarations which mean you need to adopt a slightly different approach. More Information on Namespaces
The default namespace needs to be used in the query, like so:
<?php
$id='NFDBB2FA9-tu26';
$file='my.xlf';
$dom=new DOMDocument;
$dom->load( $file );
$xp=new DOMXPath( $dom );
# We need to use this in the XPath query - this could be almost anything but best kept short!!
$xp->registerNamespace('f','urn:oasis:names:tc:xliff:document:1.2');
# Not essential to declare the following when simply querying against the default namespace
$xp->registerNamespace('okp','okapi-framework:xliff-extensions');
$xp->registerNamespace('its','http://www.w3.org/2005/11/its');
$xp->registerNamespace('itsxlf','http://www.w3.org/ns/its-xliff/');
$xp->registerNamespace('xml','http://www.example.com');
# note how each portion of the XPath expression uses our namespace prefix..
$col=$xp->query( '//f:xliff/f:file/f:body/f:trans-unit[@id="'.$id.'"]/f:target' );
if( $col && $col->length ){
foreach( $col as $node ){
$node->nodeValue='Big Bold Brave Banana';
}
}
printf('<textarea cols=180 rows=40>%s</textarea>',$dom->saveXML());
?>
