XSLからテキスト、 'fmt'の等価物

Question

テキストをプレーンテキストファイルに含む<paragraph>タグを持つXML文書を処理しています。奇妙な場所で線が折れることがあり、時には長すぎることもあります。私は単純にapply-templateアクションを実行し、いくつかの改行を追加する段落のテンプレートを持っています。 （正規化された幅にテキストの流れをrewraps）UNIX「FMT」コマンドに似た段落内

（テキストを再フォーマットする方法はあります）後に適用され、テンプレートが他を処理する機会を持っています段落内のタグ（太字、emなど）

また、プレーンテキスト文書のブロック引用で通常行うように、各改行された行をインデントする方法はありますか？

Answer 1

一つの簡単な解決策は次のようにFXSLからstr-split-to-linesテンプレートを使用することです。この：

Dec. 13 — As always for a presidential inaugural, security and surveillance were 
extremely tight in Washington, DC, last January. But as George W. Bush prepared to 
take the oath of office, security planners installed an extra layer of protection: a 
prototype software system to detect a biological attack. The U.S. Department of 
Defense, together with regional health and emergency-planning agencies, distributed 
a special patient-query sheet to military clinics, civilian hospitals and even aid 
stations along the parade route and at the inaugural balls. Software quickly 
analyzed complaints of seven key symptoms — from rashes to sore throats — for 
patterns that might indicate the early stages of a bio-attack. There was a brief 
scare: the system noticed a surge in flulike symptoms at military clinics. 
Thankfully, tests confirmed it was just that — the flu.
