    <p>I am trying to build a E pub Reader. I am able to highlight the user selected text and i am getting the x path of that particular selected text. After that i am trying to build a function which takes x path as parameter and show the user selected text by changing background color. but its not working. </p> <p>Code:-</p> <pre><code>function uiWebview_restoreSelection() { var selectionDetails = "/HTML[1]/BODY[1]/DIV[1]/text()[1]|910|/HTML[1]/BODY[1]/DIV[1]/text()[1]|930"; //alert("selectionDetails"+selectionDetails); if (selectionDetails != null) { selectionDetails = selectionDetails.split(/\|/g); alert("selectionDetails" + selectionDetails); if (typeof window.getSelection != 'undefined') { var selection = window.getSelection(); selection.removeAllRanges(); var range = document.createRange(); var selectionDetails0 = selectionDetails[0]; alert("selectionDetails0" + selectionDetails0); selectionDetails0 = selectionDetails0.replace(/\//g, "/h:"); selectionDetails0 = selectionDetails0.replace("h:t", "t"); alert("selectionDetails0" + selectionDetails0); var selectionDetails2 = selectionDetails[2]; alert("selectionDetails2" + selectionDetails2); selectionDetails2 = selectionDetails2.replace(/\//g, "/h:"); selectionDetails2 = selectionDetails2.replace("h:t", "t"); alert("selectionDetails2" + selectionDetails2); range.setStart(document.evaluate(selectionDetails0, document, nsResolver, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue, Number(selectionDetails[1])); range.setEnd(document.evaluate(selectionDetails2, document, nsResolver, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue, Number(selectionDetails[3])); document.designMode = "on"; var newSpanMark = document.createElement("span"); document.execCommand("HiliteColor", false, "red"); range.insertNode(newSpanMark); document.designMode = "off"; } } } </code></pre> <p>Please suggest for the above problem.</p> <p>Thanks in Advance</p>

    3. COSo for my understanding: in this case you would like to highlight the characters 910 through 930 of the text node given by the XPath expression? Could you tell us what your code is doing exactly now, that is what incorrect result does it yield?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
