[GitHub] [echarts] minren118 opened a new issue, #18192: [Bug] 使用getDataURL方法获取svg文本时，当有<符号时，没进行转义破坏了xml文档结构
minren118 opened a new issue, #18192:
URL: https://github.com/apache/echarts/issues/18192
### Version
5.3
### Link to Minimal Reproduction
_No response_
### Steps to Reproduce
当使用getDataURL对图表进行svg文本输出时，发现ECharts没有对特殊的符号如<进行转义再输出，导致导出的svg文本出错。
浏览器打开会显示这样的标识，实际的内容没法渲染出来。
实际内容如下：因<破坏了xml文档结构。
当转义后，就正常了。
<text dominant-baseline="central" text-anchor="start" style="font: normal normal 14px Microsoft YaHei" x="30" y="7.5" transform="translate(85 520)" fill="#333"><5</text>
### Current Behavior
未对导出的字符串进行转义。
### Expected Behavior
需要对导出的字符串包含特殊字符时，转义后再输出。
### Environment
```markdown

**TITLE**
[Bug] When using the getDataURL method to get svg text, when there are < symbols, it is not escaped and destroys the xml document structure
**BODY**
### Version
5.3
### Link to Minimal Reproduction
_No response_
### Steps to Reproduce
When using getDataURL to output the svg text of the chart, it is found that ECharts does not escape and re-output special symbols such as <, resulting in an error in the exported svg text.
When the browser opens, it will show such a logo, and the actual content cannot be rendered.
The actual content is as follows: the XML document structure is broken by <.
When escaped, it is normal.
<text dominant-baseline="central" text-anchor="start" style="font: normal normal 14px Microsoft YaHei" x="30" y="7.5" transform="translate(85 520)" fill="#333"><5</text>
### Current Behavior
The exported string is not escaped.
### Expected Behavior
If you need to include special characters in the exported string, escape it before output.
### Environment
```markdown
- OS:
- Browser:
- Framework:
```
