xml - 来自命令行的 Saxon-HE 9.6 的换行符分隔输出

Question

有没有办法在 Saxon-HE 9.6 的多个匹配节点上获取换行符分隔的输出？

我使用这个名为 saxon-lint 的包装器:

#!/bin/bash

java -cp /path/to/saxon9he.jar net.sf.saxon.Query -s:"$2" -qs:"$1" !method=text

示例:

文件.xml

<house_pet_hazards>
  <hazard type="cleanup">
    <name>hairballs</name>
    <guilty_party species="cat">Dilly</guilty_party>
    <guilty_party species="cat">Nameless</guilty_party>
    <guilty_party species="cat">Katie</guilty_party>
  </hazard>
</house_pet_hazards>

命令行:

$ saxon-lint '/house_pet_hazards/hazard/guilty_party' file.xml

输出:

DillyNamelessKatie

预期输出:

Dilly
Nameless
Katie

编辑

I've found a semi-working solution by searching google hardly 提出的 Michael Kay ，所以我写了这个包装器:

#!/bin/bash

xpath="$1"
[[ -s $2 ]] && file="$(readlink -f "$2")" || file=/dev/stdin

java -cp saxon9he.jar net.sf.saxon.Query -qs:"for \$x in doc('file://$file')$xpath
return (data(\$x),text{'
'})" !method=text

输出:

$ saxon-lint "/house_pet_hazards/hazard/guilty_party" /tmp/file.xml
Dilly
Nameless
Katie

但是我发现的问题是，当我使用路径的时候

house_pet_hazards/hazard/guilty_party

我得到错误

Error on line 1 column 37 
  XPST0003 XQuery syntax error near #...p/file.xml')house_pet_hazards/#:
    expected "return", found name "house_pet_hazards"
Static error(s) in query

或

./house_pet_hazards/hazard/guilty_party

我收到错误:

Error on line 1 column 37 
  XPST0003 XQuery syntax error near #... doc('file:///tmp/file.xml')./#:
    expected "return", found "."
Static error(s) in query

当然，只需将您的查询字符串更改为:

-qs:"string-join(/house_pet_hazards/hazard/guilty_party,'
')"

您也可以缩短到 //guilty_party 的路径。

Cygwin 中的示例 bash 脚本:

[/cygdrive/c/apps/SaxonHE9-6-0-3J]
==> cat saxon-lint.bsh
#!/bin/bash.exe

java -cp saxon9he.jar net.sf.saxon.Query -s:$2 -qs:"string-join($1,'
')" !method=text

[/cygdrive/c/apps/SaxonHE9-6-0-3J]
==> ./saxon-lint.bsh //guilty_party so.xml
Dilly
Nameless
Katie
