TS 文件格式用于 Qt Linguist 的描述是通过 DTD presented below, which we include for your convenience. Be aware that the format may change in future Qt releases.
<!-- ! ! Some notes to the DTD: ! ! The location element is set as optional since it was introduced first in Qt 4.2. ! The userdata element is set as optional since it was introduced first in Qt 4.4. ! The vanished message type was introduced first in Qt 5.2. ! --> <!-- ! Macro used in order to escape byte entities not allowed in an xml document ! for instance, only #x9, #xA and #xD are allowed characters below #x20. --> <!ENTITY % evilstring '(#PCDATA | byte)*' > <!ELEMENT byte EMPTY> <!-- value contains decimal (e.g. 1000) or hex (e.g. x3e8) unicode encoding of one char --> <!ATTLIST byte value CDATA #REQUIRED> <!-- ! This element wildcard is no valid DTD. No better solution available. ! extra elements may appear in TS and message elements. Each element may appear ! only once within each scope. The contents are preserved verbatim; any ! attributes are dropped. Currently recognized extra tags include: ! extra-po-msgid_plural, extra-po-old_msgid_plural ! extra-po-flags (comma-space separated list) ! extra-loc-layout_id ! extra-loc-feature ! extra-loc-blank --> <!ELEMENT extra-* %evilstring; > <!ELEMENT TS (defaultcodec?, extra-**, dependencies?, (context|message)+) > <!ATTLIST TS version CDATA #IMPLIED sourcelanguage CDATA #IMPLIED language CDATA #IMPLIED> <!-- The encoding to use in the QM file by default.

If the line is omitted, the location specifies only a file. ! ! location supports relative specifications as well. Line numbers are ! relative (explicitly positive or negative) to the last reference to a ! given filename; each file starts with current line 0. If the filename ! is omitted, the "current" one is used. For the 1st location in a message, ! "current" is the filename used for the 1st location of the previous message. ! For subsequent locations, it is the filename used for the previous location. !
