eXist-db中XSL-FO文件的验证错误（使用Jing和Jaxp）

时间：2016-03-02 12:08:43

标签： xsl-fo exist-db

我正在基于eXist-db在我的应用程序中密集测试pdfs的制作。验证方案非常简单：

let $doc := xmldb:document('/db/apps/my-app/data/test.fo')
let $grammar := xmldb:document('/db/apps/my-app/resources/catalogs/fop.xsd')
let $validator1 := validation:jaxp-report($doc, false(), $grammar)
let $validator2 := validation:jing-report($doc, $grammar)
return
    ($validator1, $validator2)

结果1：

<report>
    <status>invalid</status>
    <namespace>http://www.w3.org/1999/XSL/Format</namespace>
    <duration unit="msec">135</duration>
    <message level="Error" line="1" column="95">cvc-elt.1.a: Cannot find the declaration of element 'fo:root'.</message>
</report>

结果2：

</report>

服务器的控制台：

[Fatal Error] :-1:-1: Premature end of file.

我无法追踪问题所在。但是，pdf是通过FOP顺利生成的。我检查了所有文件的mime类型，试图返回文档，语法，结果，但它总是向控制台抛出相同的内容。

我使用的是eXist 3.0.RC1

答案 0 :(得分：2)

这个具体问题已于2010年https://github.com/relaxng/jing-trang/commit/db858d18a8c7e6e525bd5df25b1054b7f8d26e95修复;在eXist-db中，旧的20091111版本仍在使用中。

我显然错过了@georgebina一直在维护代码库;我将尝试更新eXist-db 3.0版本的JAR文件。

我提交https://github.com/eXist-db/exist/issues/965作为提醒我。

请注意

[Fatal Error] :-1:-1: Premature end of file.

是与撒克逊有关的问题，与Jing无关。
