XML. com. Combining Stylesheets with Include and Import. November 0. 1, 2. The xsl: include and xsl: import instructions give. XSLT stylesheets programmatically. In XSLT, the xsl: include and. This. modular approach also makes it possible to share parts of a. Customizing an existing stylesheet without actually editing. The xsl: include instruction is similar to the. The XSLT processor replaces it with the contents of the. For example, the. In other words, everything between its xsl: stylesheet. XSLT - <template> XSLT - <value-of> XSLT - <for. This template rule has a pattern that identifies <student. The following XSLT template is used to find the factorial of a given number. Example: suppose I have A, B1, B2, C1, C2, C3. ZVON > References > XSLT Reference: Intro / Search / ZVON : Go to standard Element: <call-template> attributes. Unlike. the include mechanisms offered by some programming languages. There's no limit to the levels of inclusion that. The xsl: include element can go anywhere you want in a. Putting an xsl: include instruction inside another. XSLT <xsl:call-template> Element Complete XSLT Element Reference. Call a template named 'description' when the processor finds a car element: <xsl:template match='car'> <xsl. Call xslt template with parameter. I have this xslt: <xsl:template name='dumpDebugData'> <xsl. The example above is simple. A large, complex stylesheet like the. Doc. Book files into HTML (see Norm Walsh's Doc. Book XSL. stylesheet) uses xsl: include on a larger scale. Of the 6. 2. XSLT instructions in version 1. Using xsl: include doesn't change XSLT's approach to. If the XSLT. processor can't find one template that is more specific than another. Using. xsl: include does increase the chance of this error happening. The xsl: import instruction is similar to xsl: include. For. example, the following makehtml. XSLT. processor to import the inlines. The syntax is nearly. Both. makehtml. 2. The. XSLT processor will add emphasis element nodes to the result. Thus the XSLT. processor knows that when it finds a template rule with the same match. For a more industrial- strength demonstration of the difference. I use to create HTML versions of this. Because I'm using the Doc. Book DTD, I use the aforementioned Doc. Book stylesheets by. Norm Walsh, but I wanted to make various changes to my own copy of the. For example, Norm's stylesheets italicize all. I want emphasized text within. XML documents stand. I just zipped up all the stylesheet files and unzipped them. The complete main stylesheet that I now use to. HTML version of this column looks like the following.< xsl: stylesheet xmlns: xsl=. Here. are two of the edited xsl: template elements: < !- - (db. Mods. xml excerpt) - ->. When you download the Doc. Book. stylesheet, it has a template rule with a pattern of . Because the. db. Mods. Taking these revisions from my Linux notebook to my Windows. I just bring the db. XSL Transformations (XSLT)This specification defines the syntax and semantics of XSLT, which is a. XML documents into other XML documents. XSLT is designed for use as part of XSL, which is a stylesheet language. XML. In addition to XSLT, XSL includes an XML vocabulary for specifying. W3. C's role in making the. Recommendation is to draw attention to the specification and to promote its. This enhances the functionality and interoperability. Web. The list of known errors in this specification is available at http: //www. REC- xslt- 1. 99. Comments on this specification may be sent to xsl- editors@w. Thus this specification is a definition of the syntax. XSLT namespace. A transformation expressed in XSLT describes rules for transforming a. In constructing the result tree, elements from the source tree can be. A transformation expressed in XSLT is called a stylesheet. A template can contain elements that specify literal. Instructions can select and process. Note that elements are only processed when they have been selected. However, only. one template rule will be applied. The method for deciding which template. XSLT allows a. simplified syntax for such stylesheets (see . The current node is. Only a few instructions change the current node. This version of XSLT does not define a. Elements from the XSLT namespace are recognized only in the. The complete list of XSLT- defined. Instead, any extension must be in a. However, XSLT stylesheets are free to use any. URI of the XSLT namespace. An element from the XSLT namespace may have any attribute not from the. XSLT namespace, provided that the expanded- name of the. URI. Thus, an XSLT processor is always free to ignore such attributes. URI. Such attributes can provide, for example, unique. It is an error for an element from the XSLT namespace to have attributes. URIs (i. e. Thus, an XSLT processor is always free to ignore. URI. Such elements can. For example< html xsl: version=. When the. xsl: version attribute is not equal to 1. Thus, a literal. result element used as a stylesheet cannot contain top- level elements. In some situations, the only way that a system can recognize that an XML. XSLT processor as an XSLT stylesheet is. XML document itself. For example. < xsl: stylesheet version=. The xsl: include element has an. URI reference identifying the. For example, if stylesheet B includes. A, stylesheet C includes stylesheet. A, and stylesheet D includes both stylesheet. B and stylesheet C, then A will be. D twice. An. xsl: stylesheet element in the import tree is defined to have. The import tree will have a separate. NOTE: If xsl: apply- imports is used (see . However, an XSLT. Two forms of embedding. XSLT stylesheet may be textually embedded in a non- XML resource. XML document. other than as the document element. To facilitate the second form of embedding, the. ID attribute that. NOTE: In order for such an attribute to be used with the XPath id function, it must. DTD as being an ID. The following example shows how the xml- stylesheet processing. In particular, it may have text. When written out. XML output method (see . The. XSLT processor may use the public identifier to generate a URI for the entity. URI specified in the system identifier. As in. XML, a whitespace character is #x. D or #x. A. An ancestor element of the text node has an xml: space. Otherwise, the text node is stripped. The xml: space attributes are not stripped from the tree. NOTE: This implies that if an xml: space attribute is. For stylesheets, the set of whitespace- preserving element names consists. Category: top- level- element - -> < xsl: strip- spaceelements = tokens /> < !- -. Category: top- level- element - -> < xsl: preserve- spaceelements = tokens /> For source documents, the set of whitespace- preserving element names is. If. an element name matches a Name.

It. finds an employee's department and then processes the group. The first table is filled with domestic sales while the second. For example, given a source document. For example. < xsl: template match=. This may present a denial of service. Conflict Resolution for Template Rules. It is possible for a source node to match more than one template rule. The. template rule to be used is determined as follows: First, all matching template rules that have lower import precedence than the matching. Next, all matching template rules that have lower priority than the. The value of this. Number with an optional. When an. xsl: for- each element is instantiated, the current template rule. The value of. the name attribute is a QName, which is. The created element node will have the. XSLT namespace. The created element node will also have a copy of the namespace nodes that. XSLT namespace URI. XSL/Transform), a namespace URI declared. The namespace bound to each of the prefixes is. This applies to: the namespace URI in the expanded- name of a literal result element.

Instantiating the xsl: copy element creates a copy. This is used. only when copying element nodes. The root node is treated specially because the root node of the result. If a stylesheet defines the. It also assumes that if more than one such element. In. addition, xmlns attributes are not interpreted as attribute. XML Namespaces. Recommendation to do this. The following example creates an img result element from a. The value attribute contains an expression. For example. the following example numbers a sorted list: < xsl: template match=. The following attributes control how the. The level attribute specifies what levels of the source. The default is. single. The count attribute is a pattern that specifies what. If there is no such ancestor, it constructs an empty list. Preceding siblings has the. When level=. Preceding siblings has the same meaning here as with the. When level=. If the from attribute. The list of numbers is then converted into a string using the attributes. This is. intended for a document that contains a sequence of chapters followed by a. Chapters are numbered 1, 2, 3; appendices. A, B, C; sections in chapters are numbered 1. A. 1, A. 2, A. 3.< xsl: template match=. The numbers are integers greater than 0. The. attributes are all optional. The main attribute is format. A format token A generates the sequence A B C .. Future versions. of XSLT may provide additional attributes to provide control over these. The select attribute is required. The. xsl: if instruction provides simple if- then conditionality; the. Conditional. Processing with xsl: if< !- - Category. Content: template - -> < /xsl: if> The xsl: if element has a test attribute, which. The content is a. In the following example, the names in a group of names. It consists of a sequence of xsl: when elements. The content of. the xsl: when and xsl: otherwise elements is a. If no. xsl: when element is true, and no xsl: otherwise. The following example enumerates items in an ordered list using arabic. For each node to be processed. The resulting object is converted to a string as if by a call to the. The default. value of the select attribute is ., which will. This string serves as a sort key for the node. For. example, if lang=. The default value is. NOTE: It is possible for two conforming XSLT processors not to sort. There are two elements that. The difference is that the value specified on the. Both xsl: variable and xsl: param have a required. A result tree fragment is treated equivalently to a node- set. However, the operations permitted on a. In particular, it is not.
