Xslt writing attributes
New tests may be added from time to time, and contributions are welcome. It will walk down the tree and do nothing else, i.
The XSLT default rules simply copy all contents to the output. This XPath abbreviation for self::node gives you the value of the current node -- in this case, the attribute value.

Other features from XPath 3. It is important to understand that the XSLT processor always works within a given context. Documentation on how to run tests is available within the test suite. However, after that ode start-tag and before the xsl:apply-template element that shows where to put the poem element's contents, it also outputs two new child elements of this ode element: an author element and a year element. It will walk down the tree and do nothing else, i. If text is available in a node or attributes, text is copied. In more easy terms, XPath allows to you precisely define what XML element s or attribute s "you are talking about". The rule of the root element is also the last one be finished since it must deal step-by-step with everything that is found inside!!! This month we'll look at how to convert attributes to result tree elements, how to grab attribute values for more general use, how to test attribute values for specific values, and how to define groups of attributes for easier re-use in multiple places in the result tree.
An xsl:if element that only has a node name as the value of its test attribute is testing whether that node exists or not; in the example, the first xsl:if element tests whether the para element has a flavor attribute.
Bob DuCharme Once an XML document is read into a source tree, where an XSLT stylesheet can get a hold of it, there's a lot that the stylesheet can do with the source document's attribute values.
Note how this attribute name is in the plural; the value can list more than one attribute set as long as spaces separate the names and all the names represent existing xsl:attribute-set elements.
The only incompatibilities with XSLT 2.
Status of this Document This section describes the status of this document at the time of its publication. If you forget to write a rule for a tag or misspelled tag names this will happen The hue attribute takes its value from the color attribute value of the input thnad attribute. The number attribute has the contents of the thnad element's amount child as its value. It will walk down the tree and do nothing else, i. The following style sheet has the same effect as the previous one, but it uses xsl:element elements instead of literal result elements. The result of applying this stylesheet to the short source document shown earlier shows each attribute's name and value. When its first template rule sees a poem element, it outputs its contents with xsl:apply-templates and surrounds those contents with ode tags, effectively renaming the element from poem to ode.
W3C's role in making the Recommendation is to draw attention to the specification and to promote its widespread deployment. The following XSLT style sheet demonstrates this. Surround one or more of these xsl:value-of elements with an xsl:element element or with the tags of a literal result element that is, an element from outside the XSLT namespace that an XSLT processor will pass to the result tree unchanged and you'll add a new element to the result tree whose content was an attribute value in the source tree.
In case - and this is a very rare situation - you need to output an opening tag that you cannot close in the same template, then you are in trouble.
The result of applying this stylesheet to the short source document shown earlier shows each attribute's name and value. When its first template rule sees a poem element, it outputs its contents with xsl:apply-templates and surrounds those contents with ode tags, effectively renaming the element from poem to ode.
The pos attribute makes a function call and does a little math with it to create its result value: it adds 6 to the value of the element node's position within its parent node.

The following style sheet has the same effect as the previous one, but it uses xsl:element elements instead of literal result elements. Another important aim is to improve the modularity of large stylesheets, allowing stylesheets to be developed from independently-developed components with a high level of software engineering robustness. This is a Recommendation of the W3C. The result of applying this stylesheet to the short source document shown earlier shows each attribute's name and value. These links are indicated visually by a superscript identifying the target specification: for example XP30 for XPath 3. Testing for Attribute Existence and for Specific Attribute Values Sometimes, when an attribute is optional for a particular element, you want to test whether it was specified or not. Because the para element doesn't have one, the string "There is a font attribute" does not show up in the result. This is why you will see your XML contents lumped together in case you forgot to write templates.
