Skip DOCTYPE line and prefix for namespace

mrame · October 20th, 2009, 04:06 AM

I'm using xslt 2.0 and saxon 9.I'm processing an xml database from my xslt script. The xml files contains DOCTYPE declaration with a dtd path, where the dtd may not be present. Also the parent element does not contain the namespace declaration for a prefix (ce - ce:display) present in child element (ce:display).Due to these two issues, I get errors. Is there any way to skip the DOCTYPE line and namespace missing error?Any idea is appreciated.

You can't make the XML parser ignore the DTD entirely, but you can use an EntityResolver to make it use a different "dummy" DTD. The EntityResolver that most people use is the one that comes with Oasis catalogs.

If there's a namespace declaration missing, that's a much tougher problem. It means your document isn't well-formed XML, and Saxon (in fact, XSLT processors generally) can only handle well-formed XML input. There are many benefits in designing your application to use XML as the format for passing data from one component to another, and you lose all these benefits if you try to pass ill-formed XML. So you need to fix the root cause of this problem.

I will fix those errors and try the transformation part. Thank you.

I tried to create a catalog.xml file which contains the local path for the DTD.
Then I tried to run the below line from DOS command line:
java -cp C:\saxonsa9-1-0-6j\saxon9.jar;resolver.jar -Dxml.catalog.files=catalog.xml net.sf.saxon.Transform -r:org.apache.xml.resolver.tools.CatalogResolver -x:org.apache.xml.resolver.tools.ResolvingXMLReader -y:org.apache.xml.resolver.tools.ResolvingXMLReader -xsl:Lali_graphic.xsl -s:MAIN.xml -o:fig.xml
While doing so I get errorr:
"Exception thrown by URIResover: Malformed URL (E:/42021891/main.xml)(base xsl file name): unknown protocol: e
input xsl:
Same error occurs for both the below lines:
<xsl:variable name="graphics" select="document('E:/42021891/main.xml')//ce:link"/>
<xsl:variable name="stripin" select="document('E:/42021891/main.xml')//mml:math"/>
Input E:/42021891/main.xml:
<?xml version="1.0" encoding="utf-8"?><!DOCTYPE chapter PUBLIC "-//ES//DTD book DTD version 5.3.0//EN//XML" "book530.dtd" [<!ENTITY fx1 SYSTEM "fx1" NDATA IMAGE>]><chapter><info><ce:link locator="fx1"/><ce:link locator="fx3"/><mml:math altimg="si1.gif"><mml:mtext>to check</mml:mtext></mml:math>
Catalog file:
<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog " prefer="public">
<group>
<public publicId="-//ES//DTD book DTD version 5.3.0//EN//XML" uri="E:/spiina1004z/Technology/BPR/TechUtilities/DTD/07-Book530/book530.dtd"/>
</group>
</catalog>
Is there anything I'm missing or doing wrong? Any help is appreciated.

You need to get out of the habit of using Windows filenames in places where the specs require a URI or URL. Some software permits this, but in general, it's against the rules and some software will rightly reject it.

Use file:///e:/my/file/name

You are simply great. Many thanks Mike. I will follow the global rule for file path in future. Thanks again.
