34 checks available
| Check | Severity | Description |
|---|---|---|
| template-match-are-you-confusing-variable-and-node | warning | A variable name is used bare as a node selector. Use $name syntax to reference the variable. |
| template-match-blank-nested-if | warning | A nested xsl:if inside another xsl:if is prohibited. Combine conditions with 'and' into a single xsl:if. |
| template-match-can-use-abbreviated-axis-specifier | warning | Verbose axis specifiers child::, attribute::, or parent::node() are used. Replace them with the node name alone, @, or .. respectively. |
| template-match-empty-content-in-instructions | warning | An instruction element such as xsl:for-each, xsl:if, or xsl:when has no content. Add content or remove the empty element. |
| template-match-function-template-complexity | warning | The function or template contains more than 50 XSLT elements. Split it into smaller, focused units. |
| template-match-function-template-is-not-child-of-stylesheet | error | 'xsl:function' or 'xsl:template' are used in the wrong places. Use 'xsl:function' and 'xsl:template' as child nodes of 'xsl:stylesheet'. |
| template-match-function-use-in-xslt-1 | error | 'xsl:function' is declared in XSLT version 1.0. Use a named template or upgrade the stylesheet version to 2.0 instead. |
| template-match-incorrect-use-of-boolean-constants | warning | Boolean constants 'true' and 'false' are non-empty strings, not booleans. Use true() and false() instead. |
| template-match-missing-id-in-stylesheet | warning | The '@id' attribute is missing in the 'xsl:stylesheet' element. Declare it to specify the unique identifier explicitly. |
| template-match-missing-version-in-stylesheet | warning | The '@version' attribute is missing in the 'xsl:stylesheet' element. Declare it to specify the stylesheet version explicitly. |
| template-match-monolithic-design | warning | The stylesheet contains only one template or function. Extract logic into separate, focused templates. |
| template-match-name-starts-with-numeric | warning | A variable, function, or template name starts with a digit, which is invalid in XPath. Rename it to start with a letter. |
| template-match-not-creating-element-correctly | warning | xsl:element is used with a static name. Use a literal result element instead. |
| template-match-not-using-output | error | The xsl:output instruction is missing. Declare it to specify the serialization format explicitly. |
| template-match-not-using-schema-types | warning | No built-in Schema types are used in XSLT 2.0 mode. Declare variable types with xs:string, xs:integer, or similar. |
| template-match-null-output-from-stylesheet | warning | The root template contains only variable declarations and produces no output. Add instructions that write to the result tree. |
| template-match-output-method-xml | warning | xsl:output declares method='xml' while the root template generates HTML elements. Change the method to 'html'. |
| template-match-setting-value-of-variable-incorrectly | warning | A variable is assigned via a nested xsl:value-of instead of the select attribute. Use select syntax instead. |
| template-match-short-names | warning | A variable, function, or template has a single-character name. Use a descriptive name that reveals intent. |
| template-match-starts-with-double-slash | warning | The match attribute of xsl:template starts with //, which scans the entire document tree. Use a more specific pattern. |
| template-match-stylesheet-has-no-templates | error | The stylesheet has no xsl:template elements and produces no output. Add at least one template. |
| template-match-too-many-small-templates | warning | The stylesheet has 10 or more templates with fewer than 3 child elements. Merge related small templates to reduce fragmentation. |
| template-match-unsorted-imports | warning | The 'xsl:import' elements are not sorted alphabetically by '@href'. Sort imports to improve readability. |
| template-match-unused-function-template-parameter | warning | A parameter is declared but never referenced in the function or template body. Remove it or use it. |
| template-match-unused-function | warning | A stylesheet function is never called in any match or select expression. Remove it or call it. |
| template-match-unused-named-template | warning | A named template is never invoked via xsl:call-template. Remove it or call it. |
| template-match-unused-variable | warning | A variable is declared but never referenced by $name in the stylesheet. Remove it or use it. |
| template-match-use-choose-without-otherwise | warning | xsl:choose has no xsl:otherwise branch. Add xsl:otherwise to handle unmatched cases explicitly. |
| template-match-use-double-slash | warning | The match attribute of xsl:template contains //, which triggers a full document scan. Use a more specific path. |
| template-match-use-node-set-extension | warning | The node-set() extension function is unnecessary in XSLT 2.0. Query the variable directly without it. |
| template-match-use-single-option-for-choose | warning | xsl:choose contains only one xsl:when branch. Replace it with xsl:if. |
| template-match-using-disable-output-escaping | warning | disable-output-escaping='yes' is set, which produces implementation-defined output. Use xsl:copy-of or literal elements instead. |
| template-match-using-namespace-axis | warning | The namespace:: axis is deprecated in XSLT 2.0. Use fn:in-scope-prefixes() and fn:namespace-uri-for-prefix() instead. |
| template-match-using-not-outermost-stylesheet | error | xsl:stylesheet is nested inside another element. It must be the outermost element of the document. |
