How to find highlighted text

MS Word has a feature - find text that ‘highlight’ (for example ‘Quickly find highlighted text’, ‘Word: Find highlighted text’). This function finds the most long sequence of highlighted words.

Does Aspose.Words have such feature?

Thank you.

Hi Alexander,


Thanks for your inquiry. Please try using the following code that finds a particular ‘highlighted text’ and increases the size of that text in output document.
<span style=“background-color: rgb(255, 255, 255); font-family: “Courier New”; font-size: 9pt;”>

Hope, this helps.

Hi Awais,


thank you for your answer. But I need to find all highlighted text, not a particular text.
My task is - count of highlighted blocks of text. In MS Word I can find such text by selecting checkbox ‘Highlight’ and leave text box is empty in Find dialog.

Best regards,
Alexander Dyuzhev

The difference in that the Aspose API found ‘Text Text’ sequence as three string, but Word as whole string.
Looks like Aspose API based on internal document markup instead of visual representation.

Hi Alexander,


Thanks for your inquiry. In this case, you can fix this problem by using the following code:
<span style=“background-color: rgb(255, 255, 255); font-family: “Courier New”; font-size: 9pt;”>
<span style=“background-color: rgb(255, 255, 255); font-family: “Courier New”; font-size: 9pt;”>Document doc = <span style=“font-family: “Courier New”; font-size: 9pt; color: rgb(0, 0, 128); font-weight: bold;”>new <span style=“background-color: rgb(255, 255, 255); font-family: “Courier New”; font-size: 9pt;”>Document(<span style=“font-family: “Courier New”; font-size: 9pt; color: rgb(0, 128, 0); font-weight: bold;”>“D:<span style=“font-family: “Courier New”; font-size: 9pt; color: rgb(0, 0, 128); font-weight: bold;”>\<span style=“font-family: “Courier New”; font-size: 9pt; color: rgb(0, 128, 0); font-weight: bold;”>temp<span style=“font-family: “Courier New”; font-size: 9pt; color: rgb(0, 0, 128); font-weight: bold;”>\<span style=“font-family: “Courier New”; font-size: 9pt; color: rgb(0, 128, 0); font-weight: bold;”>input_hl.docx”<span style=“background-color: rgb(255, 255, 255); font-family: “Courier New”; font-size: 9pt;”>);
<pre style=“font-family: “Courier New”; font-size: 9pt;”>doc.joinRunsWithSameFormatting();

int count = 0;
for(Run run : (Iterable) doc.getChildNodes(NodeType.RUN, true)) {
if (run.getFont().getHighlightColor().getRGB() != 0) {
count++;
}
}

System.
out.println(“count:” + count);

Hope, this helps.
