【问题】

docbook中,已经按照教程,成功的实现了用ant编译默认的webhelp了,现在打算去把此编译环境,加入到我原先自己的一套docbook编译环境中。

当前已经存在了之前可以正常通过xsltproc编译的docbook的xml源码。

其中主文件中xinclude了其他子文件:

<xi:include href="glossary.xml"/>
<xi:include href="ch01_reduced_instruction_set.xml"/>
<xi:include href="reference.xml"/>

接下来,就是去想办法使得此处的ant webhelp得以成功编译:

然后先是去把三个jar:saxon-6.5.5.jar,xercesImpl.jar,xml-apis.jar,都移到对应的文件夹

E:\Dev_Root\docbook\tools\webhelp\extensions

中了,然后修改了原先的build.properties中配置为:

xslt-processor-classpath=E:/Dev_Root/docbook/tools/webhelp/extensions/saxon-6.5.5.jar
xercesImpl.jar=E:/Dev_Root/docbook/tools/webhelp/extensions/xercesImpl.jar
xml-apis.jar=E:/Dev_Root/docbook/tools/webhelp/extensions/xml-apis.jar

然后去按照教程,建立一个build.xml文件,其中内容为:

<project>
  <property name="input-xml" value="arm_vs_mips.xml"/>
  <property name="input-images-dirs" value="images/** figures/** graphics/**"/>
  <property name="output-dir" value="../output/webhelp"/>
  <import file="E:/Dev_Root/docbook/tools/docbook-xsl-ns-1.77.0/webhelp/build.xml"/>
</project>

放到对应的arm_vs_mips的book的src目录:

E:\Dev_Root\docbook\dev\books\arm_vs_mips\src

下,然后在cygwin中,该文件夹下,执行对应的

ant webhelp

结果显示profiling\profile.xsl找不到,然后通过暂时性地,把原build.xml中的:

style="../profiling/profile.xsl">

改为:

style="E:/Dev_Root/docbook/tools/docbook-xsl-ns-1.77.0/profiling/profile.xsl">

而得以继续编译,接着,编译出现错误:

webhelp:

BUILD SUCCESSFUL
Total time: 4 seconds

对应的,倒是可以生成最开始,xinclude之前的那部分内容的,截图如下:

see part webhelp content

接下来,就是去解决,用ant编译webhelp但是出现:

[xslt] Element include in namespace ‘http://www.w3.org/2001/XInclude’ encountered in book, but no template matches.

的错误的问题了。

 

【解决过程】

1.参考:[docbook-apps] Missing Xerces Classpath definition in DocBook XSL 1.77.0 Webhelp Sample

去把

classpath="${xercesImpl.jar}

加入到profile.xsl过程中,即把:

style="E:/Dev_Root/docbook/tools/docbook-xsl-ns-1.77.0/profiling/profile.xsl">

变为:

style="E:/Dev_Root/docbook/tools/docbook-xsl-ns-1.77.0/profiling/profile.xsl" classpath="${xercesImpl.jar}">

然后在去编译看看,结果好像就解决了上述的xinclude的问题了。

 

2.不过,后来又看到上面那个帖子的回复:

Re: [docbook-apps] Missing Xerces Classpath definition in DocBook XSL 1.77.0 Webhelp Sample

又说这个设置不需要在此处加,而只需要在build.properties添加即可,但是我此处的确是已经在build.properties中添加了xercesImpl.jar的配置的。

而且也是其所说的1.8.x,即1.8.4版本的ant啊,但是此处编译的确会出错的。

而通过上述手动加在xslt中,至少是可以避免该问题的,所以,事实证明,还是需要添加classpath="${xercesImpl.jar}到xslt处理过程中的。

 

【总结】

对于docbook中用

ant webhelp

编译webhelp出现:

[xslt] Element include in namespace ‘http://www.w3.org/2001/XInclude’ encountered in book, but no template matches.

的错误的原因为,使用ant中调用xslt时,classpath中没有包含用于处理xinclude的xercesImpl.jar,所以:

解决办法为,把xercesImpl.jar的classpath添加到xslt处理过程中即可。

 

即,把build.xml中的target name="chunk"中的

<xslt 
in="${input-xml}"
out="${xincluded-profiled.xml}"

部分的:

style="E:/Dev_Root/docbook/tools/docbook-xsl-ns-1.77.0/profiling/profile.xsl">

改为:

style="E:/Dev_Root/docbook/tools/docbook-xsl-ns-1.77.0/profiling/profile.xsl" classpath="${xercesImpl.jar}">

就可以使得xercesImpl能够正常处理xinclude的xml文件了。

不过,其后又出现别的"null WrappedRuntimeException 系统找不到指定的文件"方面的错误,关于该错误的折腾结果如下:
