You can adjust any of these Settings in your PHP code, too, so don't worry if you're not sure (for example, if you set portrait-mode document layouts here, you can still create landscape documents).
您可以在您的PHP代码中调整这些设置中的任意一个，如果无法确定也无需担心(例如，如果您在此处设置的是像模式文档布局，您仍然可以创建景观文档)。
They let you do things like format your code and organize imports automatically when you save your document. To configure save actions.
在保存文档时，保存操作将允许自动执行格式化代码及组织导入之类的操作。
The problem with this approach is that it requires your handler code to always know where the parser is in the document, and to interpret the components appropriately.
这个方法存在的问题是，它需要处理程序代码始终知道解析器位于文档的哪个位置，并需要它正确地解释组件。
By so closely reflecting the document structure, it creates a tight coupling between your application code and that structure.
通过如此贴实地反映文档结构，该方法使应用程序代码和文档结构之间紧密耦合。
Your code often needs to walk through things item by item, whether it's a list, a file, or an XML document.

To try this, you can put the form on a Web site, then save the code in Listing 14 as an HTML document on your desktop.
要尝试此操作，您可以把该表单放到Web站点中，然后把清单14中的代码另存为桌面上的HTML文档。
If you're working with a stable document structure defined by a Schema or DTD, and the structure suits your application's needs, code generation is probably the best approach.
如果使用由Schema或DTD定义的稳定文档结构，并且该结构适合应用程序的需要，则代码生成方法可能是最佳方法。
If the core of your application is processing an XML document, the XML Code framework constructed by JBind may make it very easy to use.
如果应用程序的核心是处理XML文档，则使用由JBind构造的“XML代码”框架可能非常简单。
So while you work directly with SAXParserFactory in your code, JAXP might use Apache Xerces behind the scenes to handle the actual parsing of a document.
因此虽然在代码中直接使用SAXParserFactory,JAXP必须在幕后使用ApacheXerces来处理真正的文档解析。
Then, you can use the XML to SQL wizard to unit test the XML document for validity before writing your code that will use the XMLToSQL run time library.
同时，您也可以在编写使用XMLToSQL运行时库的代码之前通过XMLToSQL向导进行XML文档的单元测试。
Starting the project from within Visual Studio.net loads Excel or Word along with your Office document, and runs your code as necessary.
