InDesign CS5脚本：如何在导入XML时忽略DTD？

Question

我导入XML到InDesign，我得到这个消息：

The external entity 'blahblah.dtd' cannot be found. Continue to import anyway?

当我再继续导入XML，我得到这个错误信息：

Javascript Error!

Error Number: 103237 Error String: DOM transformation error: Invalid namespace.

Engine: session File: C:\blahblah\blahblah.jsx Line: 259 Source:
obj.doc.importXML(File(xmlDoc));

..问题是，我无法访问DTD，无论如何我都不需要它。

• 那么，有没有一个Extendscript办法忽略的DTD？
• 如果没有，是否有一种方法可以用XSLT忽略DTD？

---

下面是相关代码：

function importXML(xmlDoc, xslt) 
{ 
    with(obj.doc.xmlImportPreferences) 
    { 
     importStyle = XMLImportStyles.MERGE_IMPORT; // merges XML elements into the InDesign document, merging with whatever matching content 
     createLinkToXML = true; // link elements to the XML source, instead of embedding the XML 

     // defining the XSL transformation settings here 
     allowTransform = true; // allows XSL transformation 
     transformFilename = File(xslt); // applying the XSL here 

     repeatTextElements = true; // repeating text elements inherit the formatting applied to placeholder text, **only when import style is merge! 
     ignoreWhitespace = true; // gets rid of whitespace-only text-nodes, and NOT whitespace in Strings 
     ignoreComments = true; 
     ignoreUnmatchedIncoming = true; // ignores elements that do not match the existing structure, **only when import style is merge! 
     importCALSTables = true; // imports CALS tables as InDesign tables 
     importTextIntoTables = true; // imports text into tables if tags match placeholder tables and their cells, **only when import style is merge! 
     importToSelected = false; // import the XML at the root element 
     removeUnmatchedExisting = false; 
    } 

    obj.doc.importXML(File(xmlDoc)); 
    obj.doc.mapXMLTagsToStyles(); // automatically match all tags to styles by name (after XSL transformation) 

    alert("The XML file " + xmlDoc.name + " has been successfully imported!"); 

} // end of function importXML

好，甚至simplier。我们只需要防止交互，然后删除附加的任何dtds：

function silentXMLImport(file) 
{ 
    var doc, oldInteractionPrefs = app.scriptPreferences.userInteractionLevel; 

    if (!(file instanceof File) || !file.exists) 
    { 
     alert("Problem with file : "+file); 
    } 

    if (app.documents.length == 0) 
    { 
     alert("Open a document first"); 
     return; 
    } 

    //Prevent interaction and warnings 
    app.scriptPreferences.userInteractionLevel = UserInteractionLevels.NEVER_INTERACT; 
    doc = app.activeDocument; 
    doc.importXML (file); 

    //Remove any dtd attached to the document 
    doc.dtds.everyItem().remove(); 

    app.scriptPreferences.userInteractionLevel = oldInteractionPrefs; 
} 

//Now import xml 
silentXMLImport (File (Folder.desktop+"/foobar.xml")); 

它在这里工作。

我认为zanegray给了你主要的概念，尽管我认为你过于复杂。 为什么不只是获取xml文件内容，用正则表达式去除tetd dtd声明，然后输出一个新的XML文件，用于输入？

//Open and retrieve original xml file content 
var originalXMLFile = File (Folder.desktop+"/foo.xml"); 
originalXMLFile.open('r'); 
var content = originalXMLFile.read(); 
//Looks for a DOCTYPE declaration and remove it 
content = content.replace (/\n<!DOCTYPE[^\]]+\]>/g , ""); 
originalXMLFile.close(); 
//Creates a new file without any DTD declaration 
var outputFile = new File (Folder.desktop+"/bar.xml"); 
outputFile.open('w'); 
outputFile.write(content); 
outputFile.close(); 

然后，您可以使用此过滤XML为您的导入。

这里是一个XSLT将剥离DOCTYPE声明：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
    <xsl:template match="/"> 
     <xsl:copy-of select="."/> 
    </xsl:template> 
</xsl:stylesheet>
