我正在尝试在XLIFF文件上运行一系列模式。样本:
<trans-unit id="1">
<source> I like "sausages". </source>
<target> J'aime bien les « sausices » </target>
</trans-unit>
<trans-unit id="2">
<source> I like "sausages". </source>
<target> J'aime bien les «sausices» </target>
</trans-unit>
我解析文件,然后在每个目标元素上运行每个模式。
foreach($patterns as $p) {
if (preg_match($p['find'], $tu[0]->target, $dummy)) {
do {
$targetText = $tu[0]->target;
$tu[0]->target = preg_replace($p['find'], $p['repl'], $targetText, -1, $count);
} while ($count);
}
}
例如,我有一个带有图案的数组:
$patterns[1] = array(
'find' => "/[«‹]\K(?!\x{00A0})\s/imu",
'repl' => " "
);
$patterns[2] = array(
'find' => "/[«‹]\K(?!\p{Zs})/imu",
'repl' => " "
);
模式1应与上面的反式单元1匹配,模式2应与反式单元2匹配。模式1工作正常,但如果我运行模式2(仅限或两者),则循环永远不会结束。替换基本上取代了«或<(模式1)之后的正常(断开)空间和狭窄的空间,或者如果根本没有空间(模式1)则插入它。
我想说这个问题与第二个正则表达式有关,但我无法弄清楚该表达式有什么问题。有什么提示吗?

模式与\p{Zs}
不匹配,因此在第二种模式中向先行条件添加
