java.lang.Objectorg.eclipse.birt.report.model.api.util.XPathUtil
The XPath string helps user locate this element in desing file. It follows a subset of XPath syntax. Each node name indicates the name of the element definition and the 1-based element position in the slot. The position information is only available when the element is in the multicardinality slot.
For example,
type | examples |
element | /report/body/table[3] /library/components/grid/row[1]/cell[2]/label |
slot | /report/body /report/body/* /report/body/table/detail/row[slotName="cells"] |
property | /report/parameters/scalar-parameter[@id="2"]/@name /report/list-property[@name="images"] /report/body/text[@id="19"]/text-property[@name="content"] /report/body/text[@id="19"]/text-property[@name="content"]/@key |
structure (EmbeddedImageHandle/IncludedLibraryHandle/ResultSetColumnHandle) | /report/list-property[@name="images"]/structure[2] /report/list-property[@name="images"]/structure |
It is strongly recommended not to call
getInstance(ModuleHandle, String)
with manually created XPath
string. Much better to use XPath string returned by getXPath(Object)
.
